Fix-tuned and actively tunable waveguide band-stop filters at millimeter wave frequencies were demonstrated. The fix-tuned waveguide was measured to have up to 70 dB of isolation for the rejection band and less than 2 dB of insertion loss for the pass band. The center of the stop band for the waveguide using InP HBV EMXT surfaces was tuned from 31 to 36.3 GHz with 0 to 10 Volts of dc bias. The results indicate that with optimized design, high performance tunable millimeter-wave filters with adjustable center frequency and bandwidth can be realized.
