Abstract
PURPOSE:To provide another phase synchronous loop within phase synchronous loop which equips voltage control type oscillator to secure a small-size circuit of highly stepmultiplex type. As a result, a compact and simple-structure synthesizer of more than 1G Hz high frequency can be obtained.
