Abstract

PURPOSE:To constitute a receiver of superior frequency stability whose reception frequency variable at random frequency intervals by frequency-dividing the output of an oscillator under the control of the 2nd PLL curcuit by a frequency divider and then by performing conversion into the 2nd intermediate frequency by using its output. CONSTITUTION:An input signal from antenna 1 is converted into the 1st intermediate frequency by frequency mixer 4 with the output of the 1st local oscillator 5 of the 1st PLL circuit 28 and it is further converted into the 2nd intermediate frequency by frequency mixer 8. Part of the output of the 1st local oscillator 5, on the other hand, is mixed down with the output of oscillator 9 by frequency mixer 30 before being supplied to programmable counter 18. The output of oscillator 11 of the 2nd PLL circuit 29 is frequency-divided by M at frequency divider 10, whose output is mixed up by frequency mixer 31 with the output of oscillator 9 before being supplied to frequency mixer 8. Then, the dividing ratios of programmable counter 18 and 24 are brought under the coupling control of dividing-ratio arithmetic circuit 22.
