MAX9982 Evaluation Kit
General Description
The MAX9982 evaluation kit (EV kit) simplifies the evalu-
ation of the MAX9982 825MHz to 915MHz high-linearity
active down-converter mixer. It is fully assembled and
tested at the factory. Standard 50鈩?SMA connectors
are included on the EV kit for the inputs and outputs to
allow quick and easy evaluation on the test bench.
This document provides a list of equipment required to
evaluate the device, a straightforward test procedure to
verify functionality, a description of the EV kit circuit, the
circuit schematic, a bill of materials (BOM) for the kit,
and artwork for each layer of the PC board.
