HIGH FREQUENCY POWER AMPLIFIER

摘要

PROBLEM TO BE SOLVED: To solve a problem of an interference caused by a noise generated by an automatic power control circuit. SOLUTION: A ground 17e of an automatic power control circuit 17 of a high-frequency power amplifying apparatus is connected to a ground 13c of a power amplifier 13 via an inductive reactance element 18 preventing frequency outputted from the power amplifier 13. This prevents a noise generated by the automatic power control circuit 17 from interfering the power amplifier 13. COPYRIGHT: (C)2003,JPO
