    摘要: A method and apparatus (100) is for providing self adjustment of a multistage radio frequency power amplifier (RFPA) (200). The apparatus (100) includes a transmit input stage (150) and a controller (110). Included in the multistage RFPA (200) are N RFPA stages (201) coupled in parallel to an N-way RF splitter (210) and to an N-way RF combiner (220), and a power sense stage (225) which generates a forward power sense signal (167). Each of the N RFPA stages (210) includes an adjustable power amplifier (PA) (300). The controller (110) optimizes a gain match and a phase match of the multistage RFPA (200) by adjusting signals which are coupled to each adjustable PA (300). The adjustments are made in response to the forward power sense signal (167) while the controller (110) controls the test input stage (150) which generates a predetermined test signal (155).
