RVA Rotary Vane Attenuator

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…

A Review of Passive Waveguide Phase Shifters

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…

Exhibiting at Space-Comm Expo London

After completing a successful 1st day at Space-Comm Expo, Day 2 is now well underway. If you didn’t get a chance to meet our Technical Sales Engineer, Steve Horner yesterday, make sure to stop by Stand E33 where he will be happy to discuss how we can help with your waveguide requirements for SATCOM &…

Flann’s Waveguide Switch delivers the industry’s highest frequency model reaching 330 GHz

Waveguide Switches are an important part of RF networks and systems, and as many sectors continue to move higher in frequency, the demand for these critical instruments remains present but with new challenges surrounding manufacturability and performance. Overcoming these challenges, our new waveguide switch range has now been extended in frequency to 330 GHz (WG32/WR3.4),…
