Received-signal gain control apparatus and radio communication apparatus

摘要

A gain control part controls a gain varying part such that the gain of a received signal corresponds to the input level of the received signal in a first control mode and controls the gain varying part so as to fix the gain of the received signal in a second control mode. A setting part sets the gain control part in the first control mode in a communication state and sets the gain control part in the second control mode in a standby mode.
