SSPBMg-C400-BRE
2.2.4 HPA A
SSEMBLY
The HPA Assembly amplifies the RF signal from the Up-Converter Assembly to a power level
sufficient for transmission. Integral to this module are three HPA stages and a power conditioner
board. Other functionality includes internal power conditioning and overtemperature shutdown.
2.2.5 C
ONTROLLER
B
OARD
All of the controls, input/output communication and the decision-making, with the exception of
the critical module-level decision are performed by the micro-controller within the Up-
Converter. The Controller Board provides through the System Control interface:
•
Fault detection and indication
•
Forward RF power monitoring and indication (optional)
•
Temperature monitoring and indication
•
ON/OFF transmit switching
•
Change in the unit’s address
An ALARM will be triggered when the internal temperature of the SSPB exceeds 70
°
C. The
SSPB will continue to operate in this condition.
A FAULT signal will be sent to the user if any one of the following occurs:
•
Phase-locked loop oscillator within the synthesizer is out of lock.
•
The baseplate temperature exceeds 85
°
C
•
Any of the RF devices fails
In case of over-temperature (>85
°
C), the SSPB will automatically restart when its internal
temperature decreases to 60 °C.
