Description
Waveguide high directional coupler WCHB-XX type 28WCHB-40_Cu, operating from 26.5 to 40GHz, has a 40dB coupling. 28WCHB-40_Cu covers the WR28 full waveguide band and comes with three flanges FBP320(UBR320). The coupling port is on H-plane bend. It can handle 110W continuously and 50KW peak power. The A-INFO's waveguide high directional coupler 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.
