Has two mos transistors as series switches and a third as impedance transformer. C5, C6, and C8 are charged to voltages proportional to phase difference between programmed dilvider's output and reference signal. Voltages are summed with pretuning voltage to control vco of frequency synthesizer for military uhf transceiver.-L. F. Blachowicz, Dial any Channel to 500 Mhz, Electronics, 39:9, p 60-69.
