Abstract:
A radio transceiver having a receive mode and a transmit mode, said radio transceiver comprising:transmitter means having an output thereof for connection to an antenna circuit to transmit a signal when said radio transceiver is in said transmit mode,receiver means having an input thereof for connection to said antenna circuit to receive a signal when said radio transceiver is in said receive mode;first means for activating and de-activating said transmitter means, said first means including a controllable voltage source, said transmitter means having power level controlled by a voltage of the voltage source;transistor means for activating and de-activating said receiver means; andcontrol means connected to said first means and transistor means such that:when said radio transceiver is in said receive mode, said first means, responsive to said control means, de-activates said transmitter means and said transistor means, responsive to said control means, activates said receiver means; andwhen said radio transceiver is in transmit mode, said first means, responsive to said control means, activates said transmitter means and said transistor means, responsive to said control means de-activates said receiver means.
