ABSTRACT:
A method and a device for increasing the battery life of a battery in a handheld radio transmitter/receiver are disclosed. The disclosed method comprises the steps of rectifying radio-frequency waste energy which is not radiated from an antenna to produce a direct current and directing that current back to the battery of the handheld radio transmitter/receiver. The disclosed device comprises an amplifier for amplifying a transmit signal and sending the transmit signal to an antenna. The disclosed device also comprises an isolator for diverting energy reflected from the antenna and a rectifier for rectifying that diverted energy to produce a direct current which is supplied back to the battery of the handheld radio transmitter/receiver.
