RFFC5071A & RFFC5072A Wideband Synthesizer/VCOs

Qorvo RFFC5071A and RFFC5072A Wideband Synthesizer/VCOs are reconfigurable frequency-conversion devices with an integrated fractional-N phase-locked loop (PLL) synthesizer, a voltage-controlled oscillator (VCO), and either one or two high-linearity mixers. The fractional-N synthesizer utilizes an advanced sigma-delta modulator that produces ultra-fine step sizes and low spurious products. The VCO features temperature-compensation circuits that deliver stable performance over the operating temperature range of 40°C to +85°C. The PLL/VCO engine, combined with an external loop filter, enables the generation of local oscillator (LO) signals from 85MHz to 4200MHz. The LO signal is buffered and routed to the integrated RF mixers, which convert frequencies from 30MHz to 6000MHz. The mixer bias current is programmable and can be reduced for applications demanding lower power consumption.
