Abstract

A portable radio telephone comprises a receiver section including at least an RF amplifier and a first frequency mixer. The telephone also comprises a battery which supplies a first voltage to the receiver section when the telephone is in portable use. When the telephone is mounted on a vehicle, a vehicle battery applies a second voltage which is higher than the first voltage, to the RF amplifier and to the frequency mixer. By this higher voltage supply, the intermodulation characteristic and reception sensitivity of the receiver section can be improved in the vehicle-mounted use. On the other hand, battery saving can be achieved by the lower voltage supply in the portable use.
