<p>BATTERY SAVING FREQUENCY SYNTHESIZER ARRANGEMENT An arrangement for reducing the amount of battery supplied power to a high frequency synthesizer. The phaselocked loop section of the synthesizer is periodically disconnected from the battery supplied power. In order to prevent substantial drift of the phase-locked loop during such power interruption, means are provided for maintaining a control signal on the VCO associated with the loop that maintains the VCO frequency. By minimizing the frequency drift, the loop can be re-locked in a short period of time following each power interruption.</p> |
