4x3-1, 3, 4 Reverse Configuration Module with Auxiliary Reverse RF
Injection
Signals from the left side of the amplifier (Ports 1 and 2/3) are combined and routed
to a reverse transmitter (XMTR 1). Signals from Port 4 are routed to XMTR 3. Signals
from Ports 5/6 are routed to XMTR 4. An RF signal from an external source can
optionally be injected at Ports 3/6 and coupled with the reverse RF inputs from
Ports 2/3 and 1 and routed to XMTR 1.
Install modules as follows:

Transmitter dedicated to Ports 1/2/3 in XMTR 1

Transmitter dedicated to Port 4 in XMTR 3

Transmitter dedicated to Port 5/6 in XMTR 4
The following diagram illustrates reverse path signal flow in this module.
