Abstract

PURPOSE: When a phase control loop is formed by sending the output of voltage-control-type oscillator to the frequency converter, the value of Q of the crystal vibtator of the oscillator is made lower, thereby expanding the range of pulled-in frequency while the temperature-stability of the frequency is being maintained.
