RFFC5072A Wideband Synthesizer/VCO with Integrated 6GHz Mixer   

The RFFC5072A is a re-configurable frequency conversion device with integrated fractional-N phased locked loop (PLL) synthesizer, voltage controlled oscillator (VCO) and one high linearity mixer. 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 mixer which is 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.The RFFC5072A can be configured to work as a signal source by bypassing the integrated mixer. Device programming is achieved via a simple 3-wire serial interface. In addition, a unique programming mode allows up to four devices to be controlled from a common serial bus. This eliminates the need for separate chip-select control lines between each device and the host controller. Up to six general purpose outputs are provided, which can be used to access internal signals (the LOCK signal, for example) or to control front end components. Both devices operate with a 2.7V to 3.3V power supply.
