Abstract

PURPOSE:To realize a miniature and low-priced transceiver with SSB reception make possible by supplying a signal equivalent to the local subcarrier of an intermediate frequency signal to a mixer. CONSTITUTION:Corresponding to mixing circuits 31 and 32 of mixer 3, oscillating circuits 41 and 42 of local oscillator 4 are provided and signal generator 5 outputs a signal which contains the local carrier of the output intermediate frequency signal of mixer 3 and a double-frequency wave. At the time of the reception of a SSB wave, the signal from generator 5 is supplied to mixing circuit 32 via matching circuit 61 and switch 62. In mixing circuit 32, respective outputs of mixing circuit 31, local oscillating circuit 42 and generator 5 are mixed together so as to extract the 2nd needed intermediate-frequency component from the output component containing USB and LSB through BPF7. Consequently, an AM wave and SS wave can be both received.
