2.1.4.2.5. Crossguide Coupler (Unit 2 A1 A3 A2 DC1)
The Crossguide Coupler provide a point of connection for sampling the power of the transmit
burst before it reaches the circulator.

2.1.4.2.6. 3-Port Circulator (Unit 2 A1 A3 A2 HY1)
The function of the circulator is to provide isolation from the output of the circulator (port 2) and
the input of the circulator (port 1). This isolation safeguards the receiver components from a
mismatch occurring which may damage the ceramic output window. The third port (port 3)
provides a connection point for the TR Limiter (Unit 2 A1 A3 A2 V1) to protect the critical low
power receiver components from the higher power of the transmit signal.
