The ADF4107 from Analog Devices is a frequency synthesizer with a frequency range from 1 GHz to 7 GHz. It can be used to implement local oscillators in the upconversion and downconversion sections of wireless receivers and transmitters. It consists of a programmable dual-modulus prescaler (P/P+1), a low noise digital PFD (phase frequency detector), a charge pump, programmable reference divider and A & B counters. The synthesizer requires a 2.7 V to 3.3 V power supply.
