ADRF6720-27 Evaluation Board

Product Details

ADRF6720-27-EVALZ is a full featured evaluation board allowing all the necessary support circuitry to operate the ADRF6720-27 in its various configurations. The evaluation board includes an on-board USB to allow for register programming via the SPI port of the ADRF6720-27. 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 output of the modulator can be driven to the ADL5320 driver amplifier. The ADRF6720-27-EVALZ is a 6 layer, FR-4 based evaluation board. A +3.3 V source is required. The required software that complements the evaluation board can be found below.
