MATCHING CIRCUIT FOR TRANSISTOR AND HIGH FREQUENCY POWER AMPLIFIER

摘要

PROBLEM TO BE SOLVED: To provide a matching circuit for a transistor(TR) that adjusts an object frequency among frequencies of a broad band by using the same board without changing the configuration of strip lines of a printed circuit board. SOLUTION: The matching circuit consists of a plurality of split strip lines S2-S5 that are connected to an input side or an output side of a high frequency TR formed on printed circuit board PB and provide an inductive component and of connection members R1-R7 that interconnect a plurality of the strip lines to obtain the length of the strip lines providing an object frequency.
