The model AD850-931D202 cavity duplexer from Anatech Electronics is designed for filtering cellular transmit and receive signals within the same unit. It provides two passbands, from 806 to 824 MHz and from 902 to 905 MHz, with better than 85-dB isolation and more than 20-dB return loss. The insertion loss is less than 1.5 dB for both passbands, with power-handling capability of 100 W. The passband ripple is less than 0.2 dB. The cavity duplexer, which measures only 382 x 257 x 85 mm, is supplied with Type N female connectors. The duplexer is designed for operating temperatures from -40 to +70 deg. C.
