2.5 Duplexer

The task of the duplexer is to isolate uplink from downlink, i.e. isolate transmit path from
receive path. The pass bandwidth of the duplexer is the entire width of the uplink band and
the downlink band.

Two frequency - dependent versions of the MOR701B Power are available:

Id - No

UL frequency

DL frequency
