WR-12 Waveguide Lowpass Filter

SWF-75379340-12-L1 is an E band waveguide lowpass filter with a passband of 50 to 75 GHz and a rejection frequency from 79 to 110 GHz. Due to the corrugated design of the WR-12 waveguide, the filter also has a low side rejection frequency from DC to 47 GHz. As such, this filter can also be accepted as a bandpass filter. The filter provides a nominal insertion loss of 2.2 dB across its passband and a typical rejection of 40 dB. Since the high end cutoff frequency can be changed by modifying the design, custom designs can be offered under different model numbers.
