Description
Waveguide low pass filter 42LB-LP-18000-26500, operating from 18 to 26.5GHz, has a 0.7dB insertion loss and low VSWR 1.35:1 in the passband. The filter has a minimum rejection value of 40dB from 36 to 66.25GHz. 42LB-LP-18000-26500 covers the WR42 full waveguide band and comes with two flanges FBP220(UBR220). It can handle 35W continuously and 0.3KW peak power. The A-INFO's waveguide low 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.
