    Abstract: The circuit transimits and receive high-frequency signal used by the oscillator of the portable radio device for short-distance. The circuit comprises the oscillator (1) generating the oscillation signal of 10.2 MHz; the dividing device for a reference signal (fR) of 12.5 KHz; the phase comparator (3) comparing a reference signal (fR) with a feedback signal (fV); the loop after-effect device (4) transforming the phase margin voltage to the DC voltage; the voltage control oscillator (5) generating the frequency (fO), 35.7-41.2 MH; the transpose dividing device (6) inputted by a feedback signal (fO) using the output of a voltage control oscillator (5); the dividing controller (9) to control dividers (6-8) and the channel selecting device (10).
