Description
Waveguide bandpass filter 28LB-BP-37000-40000, operating from 37 to 40GHz, has a 1dB insertion loss and low VSWR 1.50:1 in the passband. The filter has a minimum rejection value of 30dB from 10 to 36GHz, and a minimum rejection value of 60dB from 41 to 45GHz. 28LB-BP-37000-40000 covers the WR28 sub waveguide band and comes with two flanges FBP320(UBR320). It can handle 20W continuously and 5KW peak power. The A-INFO's waveguide band filter 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, low return loss, and high rejection. Additional lengths and different flange types may be available in stock, and please contact us to inquire further.
