Description
Waveguide low power precision fixed attenuator 42WPFA-10_Cu, operating from 18 to 26.5GHz, has a 10dB nominal attenuation and low VSWR 1.05:1. 42WPFA-10_Cu covers the WR42 full waveguide band and comes with two flanges FBP220(UBR220). It can handle 0.5W continuously and 0.5KW peak power. The A-INFO's waveguide low power precision fixed attenuator is manufactured with a high precision machining process to ensure high quality and ruggedness. They are ideal for radar antenna systems, laboratory test set-ups, microwave radio, satellite communications, and other applications requiring low insertion loss, and low return loss. Various attenuation values are available under different model numbers. Different flange types may be available in stock, and please contact us to inquire further.
