Power saving arrangement for a radiotelephone

摘要

The radiotelephone of the invention includes a receiver front end (12) for amplifying a received signal and converting the amplified received signal into a first intermediate-frequency signal, an intermediate-frequency demodulator (13) for converting the first intermediate-frequency signal into a second intermediate-frequency signal to demodulate it and for producing an RSSi signal indicative of strength of the received input signal and a power limitation portion (17 or 18) for limiting power supply to the receiver front end (12) to save consumption power of the receiver when the RSSi signal exceeds a predetermined reference voltage.
