Smart power combiner

摘要

A power-combined amplifier and method are provided. In one aspect, the power-combined amplifier and method overcome problems associated with decreased output power efficiency caused by phase mismatch between constituent amplifiers.

主权项

1. A power-combined amplifier, comprising:
first and second constituent amplifiers each having a respective power output; a power combiner electrically connected to the power outputs of the first and second constituent amplifiers, the power combiner having an output configured to deliver the combined power outputs of the constituent amplifiers and having a respective isolated termination for each of the first and second constituent amplifiers; and at least one detector operably connected to the isolated terminations of the first and second constituent amplifiers and configured to measure a load excitation at each of the isolated terminations.
