WR-28 Waveguide Compact Bandpass Filter

SWF-30302313-28-B1-C is a Ka band iris resonance based compact bandpass filter with a passband center frequency of 30 GHz and rejection frequency at 60 GHz. It is designed for any oscillator with an output waveguide of WR-28 with a UG-599/U flange pattern to pass the fundamental frequency at 30 GHz and reject the second harmonic at 60 GHz. The nominal insertion loss of the filter at 30 GHz is 0.5 dB and the rejection at 60 GHz is 13 dB. This filter can be used with Eravant’s Ka band volume production oscillator with model number SOL-30312-28-G1 to suppress the second harmonic content at 60 GHz.
