  • Switched capacitor load compensator
    Patent number: 5319800
    Abstract: In a radio transceiver (11) including a voltage controlled oscillator (VCO) (24) having an output for coupling to a switchable load (32, 30), a switch (42) couples a compensating load (44) to the output of the VCO when the switchable load is in an off state. The compensating load has an impedance that compensates for the decoupling of the load impedance from the output of the VCO, thus avoiding frequency pull problems. In a further aspect of the invention a voltage variable capacitor (100) is used as the switch.
