This datasheet details the ADRF6820, a highly integrated 695 MHz to 2700 MHz quadrature demodulator with an integrated fractional-N PLL and VCO.
The ADRF6820 is a highly integrated demodulator and synthesizer designed for next-generation communication systems. It features 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 device also includes an RF switch, an on-chip tunable RF balun, a programmable RF attenuator, and two low dropout (LDO) regulators.
