DKFC5071

The DKFC5071 is complete design Kit for RFFC5071 wideband synthesizer/VCO with integrated 6GHz mixer. The RFFC5071 is a reconfigurable frequency conversion device with integrated fractional N phased locked loop (PLL) synthesizer, voltage controlled oscillator (VCO) and a 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 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 convert frequencies ranging from 30MHz to 6000MHz. The mixer bias current is programmable and can be reduced for applications requiring lower power consumption. 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.
