Achieving RVA-Like Flatness in Compact Waveguide Attenuators

As featured in everything RF Depending on the use case, cost, and performance requirements, there are a variety of waveguide-based attenuator designs suited for different applications. If a flat attenuation response across the frequency band is required, then a rotary vane attenuator (RVA) is the preferred option with a direct relationship between vane angle and…
