Note:
RFA1160/4-(ZP)-PO versions must not be operated CW for extended periods.
This version includes Thermistor protection that will reduce the transistor gain as the
dissipation increases. The optimum Duty cycles range is 10-20%
Duty cycle MUST BE controlled via the RF_gate input to J6. Duty cycling the RF input only is
insufficient. The RF_gate (TTL high) should be applied 40usec prior to the active RF signal
pulse input and should terminate with the RF input. (see below)

Bulkhead LED indicator,
RED indicates that the 24Vdc is ON, and the thermal interlocks are valid.
If the 24V supply is ON and the LED is OFF, check the AOD thermal interlock signal.
