RF IN-A/RF IN-B
Connector:
Impedance:
Note: If input power from RF_IN is lower than the rated input value, the output power will be
lower than the rated output power accordingly. This is because the PA has a fixed gain. If the
input level from RF_IN is higher than the rated value, it will result in RF output distortion and
performance deterioration. If the output power is higher than the preset FWD threshold, it may
trigger the current-limiting function. The PA will enter the auto-protection mode, and there will
be reduced RF output or even no RF output.
RF_OUT
Connector:
Impedance:
Note: RF_OUT must be connected with a load with proper impedance, otherwise the PA will
enter the auto-protection mode and there will be in no or reduced RF output.

Connected to the REMOTE (RS232) port of exciter A (with an
RS232-to-485 adapter), which is used for control and
communication between the PA and the exciter A.
DB9-M
Connected to REMOTE (RS232) port of exciter B (with an
RS232-to-485 adapter), which is used for control and
communication between the PA and the exciter B.
