摘要： An oscillator unit is configured such that a frequency adjustment unit of a synthesizer used by a controller is smaller than a frequency variation tracking capability of a demodulator connected to an output side of a frequency converter. This structure successfully combines the temperature compensation control of an oscillator unit and the receiving process of a high-frequency receiving device. Accordingly, an oscillator unit with large temperature coefficient is applicable to high-frequency receiving devices.

摘要： The demodulator in the receiving module of the invention supplies a signal produced based on a signal level detected by a first detector to a second amplifier as an amplification degree adjustment signal. With this arrangement, when a second receiver works, an AGC voltage supplied to the second receiver is already close to an ultimately converging certain value. The AGC voltage supplied to the second receiver is thus stabilized in its value, from the value close to the ultimately converging certain value to the certain value. Accordingly, a time period required from the second receiver starts working until the AGC voltage supplied to second amplifier ultimately converges into the certain value is shortened.

摘要： A receiver according to the present invention includes a first receiving (RCV) quality detector and a second RCV quality detector connected before a combining unit. The second RCV quality detector determines a quality of a signal output from at least one of a first receiving unit and a second receiving unit by a method different from that of the first RCV quality detector. A controller allows the receiver to operate in a single receiving mode when a determination result of the second RCV quality detector is not better than a predetermined level regardless of a determination result of a determination result of the first RCV quality detector not being a predetermined level. When the receiver passes in an area where the receiver cannot receive a broadcast signal, the determination result of the second RCV quality detector is not better than the predetermined level. In response, the controller allows the receiver to operate in the single receiving mode, thereby reducing power consumption of the receiver.
