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
Ω
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.
