divider Functional Block Diagram Product Description The RFFC5071A and RFFC5072A are re-configurable frequency conversion devices with integrated fractional-N phased locked loop (PLL) synthesizer, voltage controlled oscillator (VCO) and either one or two high linearity mixers.
The fractional-N synthesizer takes advantage of an advanced sigma-delta modulator that delivers ultra-fine step sizes and low spurious products.
The VCO features temperature compensation circuits that deliver stable performance across the operating temperature range of -40°C to +85°C.
The PLL/VCO engine combined with an external loop filter allows the user to generate local oscillator (LO) signals from 85MHz to 4200MHz.
The LO signal is buffered and routed to the integrated RF mixers which are used to up/down-convert frequencies ranging from 30MHz to 6000MHz.
The mixer bias current is programmable and can be reduced for applications requiring lower power consumption.
Both devices can be configured to work as signal sources by bypassing the integrated mixers.
