The RFFC2072 RF synthesiser and VCO with integrated RF mixer by RFMD is now available from RF Parts Australia .  

The RFFC2072 is a line of re-configurable frequency conversion devices with integrated fractional-N phased locked loop (PLL) synthesisers, voltage controlled oscillators (VCO) and high linearity mixers.  

The fractional-N synthesiser features an advanced sigma-delta modulator that delivers ultra-fine step sizes and low spurious products. The PLL/VCO engine combined with an external loop filter allows the user to generate local oscillator (LO) signals from 85MHz to 2700MHz.  

The LO signal is buffered and routed to the integrated RF mixer, which is used to up/down-convert frequencies ranging from 30MHz to 2700MHz. The mixer bias current is programmable and can be reduced for applications requiring lower power consumption.  

The RF device can be configured to work as signal sources by bypassing the integrated mixers. Device programming is achieved via a simple 3-wire serial interface.  

In addition, a unique programming mode in the RFFC2072 frequency converters allow 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 can be used to access internal signals or to control front-end components. The device operates with a 2.7V to 3.3V power supply.
