Qorvo RFFC2071/2072 2.7GHz RF Synthesizer/VCOs are reconfigurable frequency-conversion devices with an integrated fractional-N phase-locked loop (PLL) synthesizer, a voltage-controlled oscillator (VCO), and one or two high-linearity mixers. The fractional-N synthesizer uses an advanced sigma-delta modulator that delivers ultra-fine step sizes and low spurious products. When combined with an external loop filter, the PLL/VCO engine allows the user to generate local oscillator (LO) signals from 85MHz to 2700MHz. The LO signal is routed and buffered to the integrated RF mixers. These mixers are used to up- or down-convert frequencies ranging from 30MHz to 2700MHz.
