MAX9985 Evaluation Kit
General Description
Features
The MAX9985 evaluation kit (EV kit) simplifies the evalu-
ation of the MAX9985 dual-channel downconversion
mixer, ideal for GSM 850/950, 2G/2.5G EDGE,
WCDMA, cdma2000 ? , and iDEN ? base-station applica-
tions. It is fully assembled and factory tested. Standard
50 ? SMA connectors are included on the EV kit for the
input and output to allow for quick and easy evaluation
on the test bench.
This document provides a component list for the EV
kit, 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 schemat-
ic, and artwork for each layer of the printed-circuit
board (PCB).
