1. A boost converter for use in a transceiver to generate an output voltage that is greater than a voltage available to the boost converter, the boost converter comprising:

  • an inductor adapted to couple at a first end of the inductor to a power supply;

    a switch that is adapted to couple a second end of the inductor to the return of the power supply when the switch is closed;

    a diode coupled at the anode to the second end of the inductor;

    a capacitor coupled to a cathode of the diode and adapted to couple to the return of the power supply, the capacitor adapted to maintain an output voltage;

    a microprocessor for monitoring the output voltage, wherein the microprocessor generates a pulse width modulated signal in response to the output voltage; and

    a gate coupled to the pulse width modulated signal and to a pulse train, the gate producing a modulated pulse train, the gate further coupled to the switch such that the modulated pulse train can be used to control the switch and move the output voltage to a target voltage.
