RFMD’s new RFFC5071 frequency conversion device is available from RF Parts Australia .  

RFFC5071 is a reconfigurable frequency conversion device with integrated fractional-N phased locked loop (PLL) synthesiser, voltage controlled oscillators (VCO) and two high linearity mixers.  

The RF synthesisers take advantage of 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 85 MHz to 4200 MHz.  

The LO signal is buffered and routed to the integrated RF mixers that in turn, convert frequencies ranging from 30 MHz to 6000 MHz. The mixer bias current is programmable and can be reduced for applications requiring lower power consumption.  

RFFC5071 can be configured to work as a signal source bypassing the integrated mixers. 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 or to control front end components. RFFC5071 operates with a 2.7V - 3.3V power supply.
