Intermittent operation receiver |
摘要 |
A direct conversion type FSK receiver has an intermittent reception mode and includes a detecting and holding device in a low frequency unit and a gain control device in a high frequency unit. The receiver starts a reception operation in response to an intermittent reception control signal and controls the gain of the high frequency unit based on the detection of the received signal strength level before an interval of time during which the receiver receives a signal transmitted for the receiver and maintains the controlled gain for that interval of time. As a result, the receiver has reduced reception disturbance, which disturbance is due to intermodulation occurring when a large input signal is received.
