•
Reverse power protection fault—The RF OUT connector is disabled to
protect the device from the power being driven back into the RF OUT
connector.
•
I/Q overvoltage protection fault—The I/Q input terminals exceed the
maximum voltage, therefore the I/Q input terminals are disabled to protect
the device.
•
Thermal shutdown—The device temperature exceeds the maximum
operating temperature. The RF subsection of the device is powered off.
