Abstract

PURPOSE:To facilitate the impedance matching between a external antenna terminal and the antenna output of a high impedance of a whip antenna or the like, by using an impedance converting circuit to convert this antenna output to a low impedance. CONSTITUTION:The antenna output of a high impedance is inputted to the circuit of a high input impedance, for example, a source follower circuit. Since the AC impedance between the source and the earth cannot be lowered in the circuit, the circuit is connected to an emitter follower circuit of high input impedance and low output impedance through a coupling capacitor 7.
