Filed: 1992-03-30
Abstract: PURPOSE:To perform the integration of the whole demodulation circuit. CONSTITUTION:A radio signal of high frequency band area received by an antenna 11 and via an amplifier circuit 12 and a first BPF 13 of wideband characteristic is converted to a signal of first IF band by using a signal with prescribed frequency by a first local oscillation circuit 31.
