General Description

The MAX9986 evaluation kit (EV kit) simplifies the evalu-

ation of the MAX9986 815MHz to 995MHz base-station

downconversion mixer. It is fully assembled and tested

at the factory. Standard 50

Ω SMA connectors are

included on the EV kit’s input and output ports to allow

quick and easy evaluation on the test bench.

This document provides a list of test 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.
