5.4.1 Description
This amplifier is a Class A, fan cooled, 80W power amplifier in the frequency range 851 to 866MHz,
built into a 4U standard rack space unit. The fan-cooled amplifier is provided with an improving
linearity pre-distortion type correction circuit to give improved Output Intermodulation Intercept Point
(OIP3) and is housed in an aluminium case having an Iridite NCP finish. SMA connectors are used for
the RF input and output ports.
The amplifier has a 2 x NC-X connectors for the power supply and a Current Fault Alarm Function via
2 x 9-way D connectors (pins 1 & 2/amplifier). The unit operates from a 24V –Ve ground power
supply.
