Claims

[Scope of utility model registration request]

A voltage controlled oscillator, a divider that distributes the output of the oscillator and supplies a part to the frequency divider in the phase-locked loop, and a phase comparison between the output of the frequency divider and the output of the reference frequency generator to calculate the error voltage. a phase comparator for supplying the voltage controlled oscillator;
A PLL that provides other distributed outputs of the distributor to a transmitter/receiver, etc.
1. A PLL synthesizer device, characterized in that the distributor is constituted by a star-connected resistor network.
