DKFC2071

The DKFC2071 is a design kit for RFFC2071 RF synthesizer/VCO with Integrated RF mixer. The RFFC2071 is a reconfigurable 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 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 mixers which are used to up/down convert frequencies ranging from 30MHz to 2700MHz. Both devices can be configured to work as signal sources by bypassing the integrated mixers. The evaluation board has been configured for wideband operation. The mixer inputs and outputs are connected to wideband transmission line transformer baluns.
