Product Details

The ADRF6650-EVALZ is a 4-layer Rogers printed circuit board (PCB) and evaluates the performance of the ADRF6650. A photograph of the evaluation board is shown in Figure 1. The evaluation board contains the ADRF6650, a connector suited for a SDP-S controller board, power supply connectors, regulators, and subminiature Version A (SMA) connectors. The evaluation board requires an SDP-S controller board to allow software programming of the device.

The ADRF6650 is a high performance, dual downconverter that integrates mixers, digital switched attenuators, digital variable gain amplifiers (DVGAs), a phase-locked loop (PLL), and a voltage controlled oscillator (VCO). The device uses broadband, square wave limiting, local oscillator (LO) amplifiers to achieve an RF bandwidth of 450 MHz to 2700 MHz. Unlike conventional, narrow-band, sine wave LO amplifier solutions, the ADRF6650 allows the application of the LO either above or below the RF input, over a bandwidth of 450 MHz to 2900 MHz.

This user guide describes the ADRF6650-EVALZ evaluation board and software. For full details, see the ADRF6650 data sheet, which must be consulted in conjunction with this user guide when using the evaluation board.
