GENERAL DESCRIPTION
This user guide describes the ADRF6520-EVA L Z evaluation
board kit for the ADRF6520 dual-channel, programmable, low-
pass filters and variable gain amplifiers (VGAs) and how to
configure the evaluation board to evaluate the ADRF6520 in a
single-ended or differential configuration.
The ADRF6520 features a filter bypass mode that extends the
bandwidth greater than 1 GHz. The ADRF6520-EVA L Z
evaluation board allows the user to test all the functions and
features offered by the ADRF6520 including low-pass filtering,
analog gain control, and the on-chip rms detectors. Signal path
traces are matched and are intuitively laid out on the left and
right side of the evaluation board, providing easy interfacing
with other evaluation boards.
The ADRF6520-EVA LZ uses an SDP-S controller board to
program its signal peripheral interface (SPI) port using the
ADRF6520 Evaluation Software.
A full description and complete specifications for the ADRF6520
are provided in the ADRF6520 data sheet and should be consulted
in conjunction with this user guide when using the
evaluation board.
