Description
Waveguide high power precision fixed attenuator 229WPFA4000-30, operating from 3.3-4.9GHz,has a 30dB nominal attenuation and low VSWR 1.05:1. 229WPFA4000-30 covers the WR229 full waveguide band and comes with two flanges FDP40(UDR40). It can handle 4000W continuously and 2000KW peak power. The A-INFO's waveguide high 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. Different flange types may be available in stock, and please contact us to inquire further.
