Model 3000W1000B
4 Rev A
1.5.3 Model 3000W1000B Driver Amplifier/500 Watt Amplifier
Interconnection
•
RF outputs from the controller/driver amplifier to the 500 watt amplifier inputs are located at the rear of
the unit.
•
RF outputs from the 500 watt amplifiers to the RF inputs of the four 12-way power combiners located in
the controller cabinet.
NOTE: The coaxial cables between the inputs and outputs of the driver and the outputs of the 500 watt
amplifiers to the Inputs of the 12-way combiner are phase matched. Do not alter the coaxial
cables length or substitute other coaxial cables for them. The outputs of the sub-amplifiers will
not combine properly, if these coaxial cables are not matched in phase, this will cause low power
output and cause additional stress to be placed on the sub-amplifiers and the final combiner.
•
Fiber optic system control cables link each 500 watt amplifier to the driver amplifier for system control
signals and fault reporting.
•
9-pin sub-miniature D cable assemblies link each 500 watt power amplifier to the driver for overdrive
sense and interlock protection.
NOTE: Fiber optic and 9-pin subminiature D cables must be in place for the amplifier to operate.
