摘要： A high frequency power amplifying device has two amplifying lines. Each amplifying line has a configuration in which a plurality of amplifying stages are connected in cascade having two source voltage terminals, of which one is connected to the first amplifying stage of one amplifying line and to the remaining amplifying stages of the other amplifying line, and the other, to the first amplifying stage of the latter amplifying line and to the remaining amplifying stages of the former amplifying line. An air core coil with a low D.C. resistance, formed by spirally winding a copper wire of about 0.1 mm in diameter, is connected in series between the final amplifying stage of each amplifying line and the source voltage terminal. Since there is no signal leak in each amplifying line from the final amplifying stage to the first amplifying stage and the D.C. resistance of the air core coil is low, oscillation margin can be improved. The air core coil is inexpensive, and accordingly can contribute to the cost reduction of the high frequency power amplifying device. Air core coils are fed by a bulk feeder and mounted over a module substrate.
