Power equalizer is often used to adjust the output power of traveling wave tubes (TWT) or high power solid state amplifiers. Traditionally, a power equalizer is composed of coaxial line with electromagnetic wave absorber or microstrip line with resistance in resonance circuit. However, those structures only adapt to microwave frequency band. In this article, a millimeter wave power equalizer is fulfilled by waveguide resonant cavity with electromagnetic wave absorber. The measured results and the simulated results show a very good agreement. © 2008 Wiley Periodicals, Inc.
