Power amplifier of transistor circuit used for amplifying high frequency signal, has electrical supply conduit which is provided vertical to plane of circuit board on which transistors are arranged

摘要

The amplifier (1-1) has a planar circuit board on which a transistor (2-1-2-n) is arranged to which radio frequency signal is supplied. The input (21-1-21-n) of the transistor is supplied with the strengthened radio frequency signal, when the output (22-1-22-n) of transistor is reset. The electrical supply conduit is connected with the input and the output of the transistor. The electrical supply conduit is provided vertical to the plane of the circuit board on which transistors are arranged.
