RECEIVING DEVICE AND RECEIVING METHOD

摘要

At least one distributor that distributes a high-frequency signal received by an antenna; and a high-frequency processing unit that outputs a received signal obtained by mixing the high-frequency signal distributed by the distributor with a local oscillator frequency generated by a local oscillator that includes a voltage-controlled oscillator are included. Furthermore, a control unit that, when executing a local oscillator frequency search to investigate a correspondence between a control voltage applied to the voltage-controlled oscillator and the local oscillator frequency of the voltage-controlled oscillator, sets to a dormant state parts constituting the local oscillator that are uninvolved in operation of the local oscillator frequency search is included.
