In high-frequency systems where precision and stability are paramount, the rotary vane attenuator (RVA) remains a vital tool. Used across industries ranging from aerospace and defense to telecommunications and scientific research, the RVA enables fine control of signal levels without compromising performance. In this blog, we take a closer look at the history, applications, and…
As featured in Everything RF A RF (radio frequency) phase shifter, sometimes known as a phase changer, is a two-port device that varies the phase angle of the transmitted output signal with respect to the input signal. The ideal phase shifter would have very low insertion loss through the device, a near perfect impedance match…
Working in collaboration with CleanEarth Energy, their case study details our new Solar PV system installation and how we came to be working together.

As featured in the IMS Edition of Microwave Journal Being able to change the signal power of an RF system is a fundamental need. There are many reasons why it is preferable to attenuate the signal close to the source. When developing and testing a new product, it is often useful to bring the…
Over the last 6 months our ‘Future Waveguide’ blog series has featured many discussions about the impact waveguide has in our daily lives over several different sectors. As we bring this series to a close, we reflect on how modern life would not be possible without the presence of waveguide technology. Since the widespread use…
As with most technology, waveguide has been no exception to a miniaturisation over the years caused by a constant drive for higher frequencies. This is due to the benefits discussed in the first post of our blog series about waveguide’s future markets. However, to still achieve a useable power within these millimetric designs a higher…
As featured in Everything RF Communication links from antenna often use dual polarization as it allows a doubling of the information capacity of a wireless channel. Circularly polarized waves can offer better propagation with reduced fading and multipath losses because it is possible to receive all orientations of the signal. Signals propagating in rectangular…
The constant increase in frequency used to receive and transmit data has not just led to an increase in transfer speeds, but also greater bandwidths and the density of connections in a single area. An example of this technology now in use is commercial 5G systems which are now comparable to traditional wired systems, allowing…
As featured in EE Times Europe – Robert Huntley As RF components are crucial in any satellite, we asked Flann Microwave CEO Ian Burnage what changes the company has observed. As a child born in the mid-fifties, I watched in awe the first live transatlantic television broadcast between the U.S. and the U.K. via the…
Ever since the late 1800s, waveguide technology has played a key role in the development of our modern world. From the rapid development and standardisation during World War II with the uses of RADAR, to the microwave backhaul links in the 1950 to 60s, and more recently mobile cell networks, the world would be a…
