Title: Improvements in and relating to a frequency synthesizer
Inventor: TOLLEFSON ROBERT DEAN
IPC: H03L7/23
Filed: 1969-12-17
Abstract: 1,253,929. Frequency synthesizers. COLLINS RADIO CO. 17 Dec., 1969 [16 Jan., 1969], No. 61420/69. Heading H3A. In a frequency synthesizer producing an output signal variable through predetermined uniform frequency steps of relatively small incremental value, two fixed reference frequencies R R1 , F R2 , Fig. 1, are generated-by means of dividers 12, 14 respectively-from a higher frequency standard 11; the two reference frequencies differ by a relatively small amount which is equal to the smallest uniform increment in the output of the synthesizer. The output frequency is generated by means of two phaselocked loops, comprising phase detectors 16, 23 respectively, the outputs from which control voltage-controlled oscillators 18, 25 respectively; the output from oscillator 25 is fed back via variable divider 26 to form the second input of phase detector 23, and is subtracted from the output of oscillator 18 in subtraction circuit 20, the output from which is fed back via variable divider 21 to form the second input of phase detector 16. The final output is taken from oscillator 18; if dividers 21, 26 are of ratio N1, N2 respectively, the output frequency is F O = (N1F R1  + N2F R2 ). By putting N2=N A +N C  and N 1  = N B  - N C  we have Thus by adjusting the dividers 21, 26 by unit steps in opposite directions, the output frequency F o  may be adjusted in unit steps of (F R2 -F R1 ) i.e. the difference between the two fixed reference frequencies. In a second embodiment the output from the higher frequency standard (11<SP>11</SP>, Fig. 3, not shown) is fed in addition to a frequency multiplier (33), from which the output of the second oscillator (25<SP>11</SP>) is subtracted, the resultant being the signal applied to the divider (26<SP>11</SP>). In a further embodiment the two fixed reference frequencies are derived from source 11<SP>111</SP>, Fig. 3, by means of fixed divider 36 and dividers 42, 46 in conjunction with subtraction circuits 39, 43 respectively; the output of divider 36 is also fed to a third phase-locked loop comprising phase detector 37, voltage-controlled oscillator 48 and variable divider 50.
