とを特徴とした多バンド受信機。 A mixer circuit that converts the frequency of an input signal using a local oscillation circuit, an intermediate frequency circuit that limits the intermediate frequency pass band width of the output of this mixer circuit, a frequency discriminator that discriminates this output, and a frequency discriminator that smoothes the output of the frequency discriminator. A multi-band receiver comprising a frequency control circuit that changes the oscillation frequency of the local oscillation circuit using the DC voltage obtained by the above, and is characterized in that the intermediate frequency pass band width is widened for a predetermined time when the power is turned on and when switching bands. Receiving machine.
