General Description

The MAX9995 evaluation kit (EV kit) simplifies the evalu-
ation of the MAX9995 dual high-linearity mixer. It is fully
assembled and tested at the factory. Standard 50Ω
SMA connectors are included on the EV kit for the input
and output 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.
