High power amplifier operating point determination apparatus and method for satellite communications system
A high power amplifier operating point determination apparatus and method determines an operating point of a high power amplifier for satellite communications system. For the purpose, the apparatus employs a DC voltage converting block in a channel amplifier located at a front-end of the high power amplifier, which couples an output power of the channel amplifier and converts the coupled output power to a DC voltage. Accordingly, in a ground monitoring center, before satellite launching, there are mapped the output power value of the high power amplifier and the DC voltage level of the channel amplifier per each command step assigned to an FGM or an ALC mode. After the satellite launching, it is possible to detect the operating point and the output power level of the high power amplifier based on mapped results by using the DC voltage level as telemetry information.
