Developer: US4ICI PLL contains 2200 — 4400 MHz VCO. VCO frequency divider (multiple of 1/2/4/8/16) allows to synthesize frequencies from 137.5 MHz to 4400 MHz. A good phase noise (approximately -100 dBc/Hz, 10 kHz at a frequency of 1152 MHz). This development designed to be used as SHF LO (beacon, transverter) at a fixed frequency. …
