An external control and monitor unit may be used to operate the
SSPA ODU series amplifiers. Control and status signals are
accessed via a 32 pin interface connector or an IrDA Interface.
Operating Modes
There are three amplifier operating modes:
•
Standby
•
Transmit ON
•
Fault
Standby Mode
In this mode, the SSPA is ready for main voltage to be applied.
Transmit ON Mode
When transmit is enabled (applied to the SSPA) RF input
signals are amplified.
Fault Mode
Summary Fault
This mode exists anytime a condition detrimental to the SSPA is
detected by the power supply fault detection circuitry. Any of
the following conditions trip the fault detection circuitry:
