Claims

[Scope of utility model registration request]

In a synthesizer type multi-band receiving device, a front end and a demodulation circuit are provided corresponding to each band, and a control voltage is provided corresponding to each band and is output from the synthesizer in a time-division manner corresponding to each band. and a sample-and-hold circuit that sample-holds each of the signals and supplies the output as a tuning side control voltage to the corresponding front end.
