Cavity Duplexer Filters ISM Band

Dec. 10, 2009

Model AD2412-2462D246 from Anatech Electronics is a cavity duplexer designed for applications in the unlicensed 2.4-GHz Industrial-Scientific-Medical (ISM) band. Band 1 covers 2401 to 2423 MHz while band 2 passes signals from 2451 to 2473 MHz. Performance in both bands includes better than 75-dB isolation, less than 1.7-dB passband insertion loss, and better than 15-dB return loss. The 50-Ohm duplexer will handle up to 25 W CW input power and is designed for operating temperatures from -10 to +60 deg. C. The compact component measures 6.75 x 4 x 1.75 in., and uses Type-N female connectors.
