Duplexer architecture

The Aprisa XE duplexer designs use 5 or 6 pole band-pass inter-digital cavity filters to give the best protection from interfering signals.

Typical insertion loss is less than 1.5dB and there is over 80dB isolation between transceiver and receiver ports.

Duplexer options are available for every transmit receive split used for fixed links below 3 GHz, including duplexers for difficult band plans with very narrow transmitter to receiver spacing.

All duplexers use transmission zeros in the filters to provide better close-in attenuation to interfering signals.
