ADRF5720-EVALZ, RF Development Tools Eval Board

ADRF57xx Eval Boards for Digital Attenuators
Analog Devices Inc. ADRF57xx Evaluation Boards evaluate ADRF57xx line (ADRF5720, ADRF5721, ADRF5730, and ADRF5731) of digital step attenuators. These boards are 4-layer evaluation boards with 0.5oz (0.7mil) to 1.5oz (2.2mil) plated top and bottom copper layers, separated by dielectric materials. All RF and dc traces are routed on the top copper layer. The inner and bottom layers are grounded planes that provide a solid ground for the RF transmission lines. The middle and bottom dielectric materials of these eval boards provide mechanical strength. The overall board thickness is 62mil, which allows 2.4mm RF launchers to be connected at the board edges.
