Description
Waveguide loop coupler WHHCx-XX type 137WHHCSM-40, operating from 5.85 to 8.2GHz, has a 40dB coupling. and SMA Male connector on coupling output. 137WHHCSM-40 covers the WR137 full waveguide band, and the flange of waveguide WR137 is FDP70(UDR70). It can handle 3000W continuously and 1100KW 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.
