The ADRF6820ACPZ-R7 is a Quadrature Demodulator operates from 695 to 2700MHz, integrated fractional-N PLL and VCO. The ADRF6820 is a highly integrated demodulator and synthesizer ideally suited for next generation communication systems. The feature rich device consists of a high linearity broadband I/Q demodulator, an integrated fractional-N phase-locked loop (PLL) and a low phase noise multicore, voltage controlled oscillator (VCO). The ADRF6820 also integrates a 2:1 RF switch, an on-chip tunable RF balun, a programmable RF attenuator and two low dropout (LDO) regulators. This highly integrated device fits within a small 6 x 6mm footprint. The high isolation 2:1 RF switch and on-chip tunable RF balun enable the ADRF6820 to support two single-ended, 50R terminated RF inputs. A programmable attenuator ensures an optimal differential RF input level to the high linearity demodulator core. The integrated attenuator offers an attenuation range of 0 to 15dB with a step size of 1dB.
