Abstract:
1. A receiver device, comprising: a first signal processor section converting an incoming radio frequency signal to a lower frequency; a reception strength sensor section sensing a signal strength of the radio frequency signal; a second signal processor section carrying out a process on a signal from the first signal processor section to improve demodulation precision; a demodulator section demodulating a signal from the second signal processor section; and a power control section controlling power supply to circuits in the second signal processor section according to a result of sensing by the reception strength sensor section, wherein: the second signal processor section includes: a gain regulator circuit gain-regulating the signal from the first signal processor section; and an amplifier circuit amplifying a signal from the gain regulator circuit; and the power control section suspends power supply to the gain regulator circuit and the amplifier circuit while the result of the sensing does not meet a predetermined condition, and starts power supply to the gain regulator circuit and the amplifier circuit when the result of the sensing comes to meet the predetermined condition.
