One hundred days ago, I stepped into the role of CEO at pinkRF. 

It’s been intense, at times messy, often energizing, and above all, clarifying. These first months are never about having all the answers. They’re about asking the right questions, listening carefully, and starting to make a few key decisions. 

This is a reflection on what I’ve seen so far, what surprised me, and where we’re heading. 

When I joined pinkRF, it was clear that the company had something special. 

The team has spent years working on solid-state RF energy, solving problems that are far from trivial. What stood out to me early on was not just the technical depth, but how often customers rely on that expertise to solve challenges they couldn’t solve elsewhere. 

At the same time, the broader market is shifting. 

Electrification is accelerating. Sustainability is no longer optional. And many of the systems currently in use, especially magnetron-based ones, are starting to show their limits. 

That combination creates a real opportunity. 

But I’ve seen before that having the right ingredients is not enough. What matters is whether you can turn that into something scalable and repeatable. 

In the beginning, I deliberately slowed myself down. 

It is tempting as a new CEO to come in and start changing things immediately. But in most cases, you first need to understand what is really going on beneath the surface. 

So I spent a lot of time talking. With the team, with customers, with partners. 

Some things confirmed my expectations. Others did not. 

What became very clear is that pinkRF has a rare level of technical capability. What impressed me most was not just the knowledge itself, but the way people approach problems. There is a strong sense of ownership, curiosity, and pride in getting things right. 

At the same time, I also saw the friction that comes with working in a very R&D driven way. Projects that are hard to scale, priorities that compete, and a lot of knowledge that is not always translated into repeatable products. 

That tension is not a weakness. But it does need to be addressed. 

One of the clearest conclusions from these first 100 days is simple: we need to move from being primarily R&D driven to becoming more product led. 

That sounds simple, but in practice it is a significant shift. 

It means making choices. Not doing everything. Deciding where we standardize, where we customize, and where we say no. 

It also means taking what we already do well, our core RF technology and control, and turning it into platforms that can be used again and again, instead of starting from scratch each time. 

We have made a conscious decision to move in that direction. Not overnight, but step by step. 

A simple example of this shift came up early on.

In one of my first customer discussions, we were asked to support a highly customized solution, something we are very capable of doing. In the past, we would likely have approached it as a one off development. 

Instead, we challenged ourselves. Can this be part of a broader platform? 

That changed the conversation internally. Rather than solving just that one problem, we started defining a solution that could be reused across multiple customers with similar needs. It required more upfront thinking, and not everyone was immediately comfortable with it. But it is exactly the kind of discipline we need if we want to scale. 

Through discussions with customers and partners, a few areas keep coming back. 

Plasma applications are growing fast, especially in semiconductor and advanced material processes. 

Industrial heating is another area where the shift toward more controllable and efficient energy solutions is clearly underway. 

In many of these cases, customers are dealing with legacy systems that are becoming harder to maintain and less predictable in performance. 

What I have learned is that the conversation is often not just about power. 

It is about control. 

We are often asked about efficiency or performance, and those are important. 

But what matters more in practice is how a system behaves over time, in real conditions. 

Does it adapt when the process changes? Does it stay stable? Does it reduce the need for manual intervention?

This is where our focus on intelligent RF control comes in. 

Instead of treating the generator as a fixed output device, we see it as something that continuously adjusts, learns, and optimizes during operation. 

It is a more complex approach, but it is also where we see the most value for customers. 

Technology alone does not scale. Organizations do. 

And ultimately, it comes down to people. What gives me confidence is the team we have today. People who go deep technically, but are also open to change and willing to challenge how we work. That combination is not easy to find. 

As we grow, we are looking for more people who want to be part of that journey. People who enjoy solving complex problems, but who also want to see their work translated into real products used in the field. 

Over the past months, we have started putting more structure in place. Not to slow things down, but to make sure we can move faster in a consistent way. 

We are becoming clearer about where we focus, which opportunities we pursue, and how we bring solutions to market. 

We are also working on how we collaborate internally. Creating more ownership, reducing unnecessary complexity, and making it easier for teams to execute. 

This is still work in progress. And it will take time to get right. 

If the first 100 days were about understanding and aligning, the next phase is about execution. 

We will not get everything right immediately. That is part of building something real. 

But we are clearer now on what matters 

• where we want to play 

• how we differentiate 

• and what we need to build to get there 

The shift toward solid state RF is happening. The question is not if, but how fast and how well it can be implemented in real applications. 

Our role is to make that transition easier, more reliable, and more impactful for the people who depend on these systems every day. 

Personally, I am excited about what we are building, not because it is easy, but because it is meaningful and has real potential. 

And that is what makes this journey worth it. 

If you enjoy working at the intersection of deep technology and real world applications, and you want to help shape how solid state RF is applied in industry, we would like to hear from you. 

In an era where industrial processes demand greater precision, lower costs, and smarter energy use, one question keeps coming across sectors from food processing to plasma technology: how do we do more with less? At pinkRF, we’ve been answering that question for years — not with incremental improvements, but with a fundamental rethinking of what RF technology can deliver. 

This article explores how pinkRF is redefining efficiency in industrial, heat-demanding solutions. Along the way, we will answer one of the most common questions we hear from engineers and system designers: what is the efficiency of the RF generator? 

For decades, the dominant technology powering RF energy applications was the magnetron — a microwave tube that, while powerful, comes with serious limitations. The main pain point of the magnetron is its limited ability to adjust output power, especially in a changing environment. It’s a brute-force way of heating, and its output power degrades over time, requiring expensive maintenance and replacement in industrial applications. pinkRF 

This degradation is not just a maintenance headache; it is an efficiency problem. Every time a magnetron drifts from its optimal operating point, energy is wasted, processes become inconsistent, and product quality suffers. For industries where margins are tight and precision is critical, this is simply not good enough. 

Solid-state RF energy uses transistor technology to generate powerful RF fields, the same technology that has powered our mobile telephone networks. pinkRF This shift from vacuum tube to semiconductor isn’t just a technical upgrade; it represents an entirely new philosophy of energy delivery. 

In contrast to ordinary energy sources like convection heaters or magnetrons, solid-state RF energy offers unprecedented control and energy range, with considerable advantages in terms of system performance, size, and weight. pinkRF 

At pinkRF, we have built our entire product line around this principle. Our generators are not simply more efficient versions of older technology — they are smarter, more adaptable, and designed to integrate seamlessly into the complex, dynamic environments of modern industrial and scientific applications. 

This is one of the most important questions any engineer asks when evaluating RF systems, and it deserves a precise answer. 

In the context of RF generators, efficiency refers to how effectively the system converts input electrical power into usable RF output power to be delivered to the load. A low-efficiency generator wastes energy as heat, creates thermal management challenges, and increases operating costs. A high-efficiency generator maximizes the useful energy transfer while minimizing losses. 

pinkRF’s solid-state RF power generators are high-efficiency systems that offer a broad range of control for energy delivery, while also improving the reliability and durability of the RF energy source. pinkRF Unlike magnetrons, which operate at a fixed frequency and degrade in performance over time, pinkRF solid-state generators maintain consistent output across their operational lifetime. 

But efficiency at pinkRF means more than a single percentage number on a datasheet. It encompasses: 

• Generator efficiency — maximizing the ratio of RF output power to electrical input power, minimizing wasted heat and losses throughout the signal chain. 
• Process efficiency — delivering energy efficiently into the load enables a better process control, improved yields, a smaller footprint, and faster or higher throughput pinkRF in real-world applications. 
• Control efficiency — vector mode providing high accuracy and high-resolution control for all RF attributes of the generated signal, including frequency, level, phase and PWM modulation. pinkRF  

This multi-dimensional view of efficiency is what separates pinkRF from legacy RF providers. 

One of the most underappreciated aspects of efficiency in RF systems is control resolution. A generator that can only adjust power in large steps wastes energy between those steps — delivering either too much or too little power to the process. 

pinkRF’s solid-state microwave generators allow power to be easily adjusted in 1-W steps and are capable of pulse mode power control. pinkRF This granular control means processes can be tuned to their exact energy requirements, eliminating overshoot and waste. 

Furthermore, they integrate real-time device monitoring and fully automated operation with a user-friendly control panel, enabling easy process set-up and control. pinkRF Real-time monitoring means inefficiencies can be detected and corrected instantly — before they affect output quality or waste energy. 

Efficiency shouldn’t come at the cost of flexibility. pinkRF has designed its systems to scale to meet any demand without sacrificing performance. 

Supporting 300W, 500W, 1000W, 6kW and 10kW, pinkRF’s solid-state microwave generators are compact, and highly reliable, providing continuous wave power for ISM frequencies at 27MHz, 434 MHz, 915MHz, and 2.45GHz. pinkRF And when higher power is needed, it is possible to combine the generators to higher power levels such as 12kW, 20kW, 36kW, and beyond. 

This modular scalability means customers invest in exactly the power they need today, with a clear, efficient path to expand tomorrow. 

At pinkRF, we understand that a highly efficient generator is only part of the equation. Integrating it correctly into your system is what unlocks its full potential. 

pinkRF’s RF Energy System Design Services help customers improve system performance and provide advice on individually tailored generator configurations, applicator and designs, identifying system bottlenecks and weaknesses. pinkRF Our engineers co-develop solutions with OEM teams from concept to final product, ensuring that efficiency gains on paper translate into efficiency gains in practice. 

According to pinkRF’s founder Klaus Werner, the new generation of solid-state RF integrated circuits offers unprecedented control, efficiency, and reproducibility pinkRF — and our mission is to help every customer unlock all three. 

So, how is pinkRF redefining efficiency in RF solutions? By approaching it from every angle: 

• Technology — solid-state generators that outperform and outlast legacy magnetron-based systems 

• Control — 1-W resolution, real-time monitoring, and vector-mode precision 

• Scalability — modular architecture from 300W to 36kW and beyond 

• Expertise — end-to-end system design support that ensures efficiency is realised in the real world 

• Longevity — solid-state RF power is very robust and barely degrades over time pinkRF, meaning the efficiency you buy on day one is the efficiency you have on day one thousand 

Efficiency in RF is not just a spec. It’s a promise. And at pinkRF, it’s one we keep. 

The new MPG10kS solid-state RF generator delivers the same efficiency as magnetrons — with unmatched precision, reliability, and control. Where magnetrons wear out, solid-state keeps performing.
