機。 an antenna unit that receives a remote control signal, a high frequency amplifier that amplifies the remote control signal received by the antenna unit, and a surface acoustic wave local oscillator that outputs a local oscillation signal;
a mixer that takes as input signals the remote control signal from the high frequency amplifier and the local oscillation signal from the surface acoustic wave local oscillator and forms an intermediate frequency signal by mixing these; and the intermediate frequency signal from the mixer. a super-re-biopsy wave circuit that detects a low-frequency control signal by super-re-biopsy-waves a signal; a low-frequency filter that selectively passes the low-frequency control signal from the super-synthetic wave circuit; A remote control receiver comprising: a low frequency amplifier that amplifies a frequency control signal; and a load control section that performs control when the low frequency control signal that has passed through the low frequency amplifier is input.
