4x3-1, 2, 4 Reverse Configuration Module with Auxiliary Reverse RF
Injection Description
The 4x3-1,2,4 Reverse Configuration Module with auxiliary reverse RF injection
combines reverse inputs from Ports 4 and 5/6 and routes them to Transmitter 4; it
also routes reverse inputs from Port 1 to Transmitter 1 and from Ports 2/3 to
Transmitter 2. An RF signal from an external source can optionally be injected at
Ports 3/6 and coupled with the reverse RF input from Port 1 and routed to
Transmitter 1.
The following diagram shows how this module functions.
