Description
Waveguide low power precision fixed attenuator 12WPFA-40_Cu, operating from 60 to 90GHz, has a 40dB nominal attenuation and low VSWR 1.10:1. 12WPFA-40_Cu covers the WR12 full waveguide band and comes with two flanges FUGP740(UG-387/U). It can handle 0.2W continuously and 0.03KW 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.
