Description
Waveguide variable attenuator 28WVA-20_Cu, operating from 26.5-40GHz,has a 0.2dB insertion loss, low VSWR 1.20:1, and up to 20dB nominal attenuation. 28WVA-20_Cu covers the WR28 full waveguide band and comes with two flanges FBP320(UBR320). It can handle 1W continuously and 1KW peak power. The variable attenuator has a precision micrometer allowing for repeatable attenuation settings. The A-INFO's waveguide variable attenuator is manufactured with a high precision machining process to ensure high quality and ruggedness. The variable attenuator is an ideal component of equipment in waveguide systems where broadband attenuation is required. 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.
