ADRF6820-EVALZ, Evaluation Board for Evaluating the ADRF6820 695 to 2700 MHz Quadrature Demodulator with Integrated Fractional-N PLL and VCO

Description

• ADRF6820-EVALZ, Evaluation Board is a full featured board allowing all the necessary support circuitry to operate the ADRF6820 in its various configurations. The evaluation board includes an on-board USB to allow for register programming via the SPI port of the ADRF6820. For ease of evaluation, a footprint for an optional crystal oscillator for the PLL reference input is integrated on the board, therefore not requiring an additional signal source. The I and Q outputs of the demodulator can be outputted single-ended or differentially where the necessary SMA connectors and balun are populated. Finally, the ADRF6820-EVALZ is populated with multiple power management options including LDOs, switching regulators, and the option to bypass the power management circuitry and to directly source the ADRF6820 with external power supplies
