2.3.15.6 4-way Hybrid Combiner with Reject Loads
The 4-way,
90 deg., balanced (hybrid) combiner is used to combine the output of the four (4)
HPA’s in each HPA sub-system HPA set. The 4-way hybrid combiner is connected to each HPA
RF output using 7/8” blind mate connectors.
Two (2) low power reject loads (with heat sinks) are used to terminate unwanted signals after
the first combining stage.
A high power reject load (with heat sink) is used to terminate unwanted signals after the final
combining stage.
Temperature sensors are mounted to the reject load heat sinks, allowing the TSC to monitor
the temperature of each reject load and prevent overheating.
