C-Band HPA Redundancy Switch



This is a well designed C-Band HPA Redundancy Switch assembly that is ideal for situations where the two C-Band  HPAs are of different power. Each HPA output is controlled via variable attenuators , ensuring that when the automatic transfer is made the standby HPA has been pre-calibrated and is putting out at the same power level as the primary amplifier.

The two attenuators shown in the photograph can be locked into position after the HPAs output has been tested.
