Abstract

PURPOSE: To constitute a receiver of superior frequency stability whose reception frequency is variable at random intervals by frequency-dividing the output of the 2nd PLL circuit and then by supplying a mixture of the division output and the output of the 1st PLL circuit to the 1st PLL circuit.
CONSTITUTION: An arrival signal from antenna 1 as converted into an intermediate frequency by frequency mixer 4 with the output of oscillator 5 of the 1st PLL circuit 28. The output of oscillator 11 of the 2nd PLL circuit 29, on the other hand, is divided by M at frequency divider 10, the output of which is supplied to via low- pass filter 9 and mixed with part of the output of oscillator 5 by frequency mixer 8, whose output is frequency-divided by programmable counter 18 and phase-compared to the output of reference frequency generating circuit 17 by phase comparator 20, thereby applying the output to varactors 6 and 3. Dividing-ratio setting circuits 21 and 25 setting dividing ratios N and n of the 1st and 2nd programmable counters 18 and 24 are brought under the coupling control of dividing-ratio arithmetic circuit 22.
