Abstract

An 18-30 GHz harmonic reject filter has been designed using a distributed prototype. The aspect ratio of the coupled suspended stripline structure is chosen to equalize the even- odd-mode electrical lengths when considering the open-end effects, The measured insertion loss is about 1 dB in the passband and more than 40 dB rejection up to twice the center frequency.
