Description
General purpose waveguide fixed attenuator 187WFA-30, operating from 3.95 to 5.85GHz,has a 30dB attenuation at the center frequency and low VSWR 1.15:1. 187WFA-30 covers the WR187 full waveguide band and comes with two flanges FDP48(UDR48). It can handle 8W continuously and 8KW peak power.The A-INFO's general purpose waveguide 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.
