MAX9982 Evaluation Kit
General Description
Features
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 50Ω SMA connectors
are included on the EV kit for the inputs and outputs to
allow quick and easy evaluation on the test bench.
♦ Fully Assembled and Tested
♦ +26.8dBm Input IP3
♦ +13dBm Input 1dB Compression Point
♦ 825MHz to 915MHz RF Frequency
♦ 725MHz to 1085MHz LO Frequency
♦ 70MHz to 170MHz IF Frequency
♦ 2dB Conversion Gain
♦ 12dB Noise Figure
♦ -5dBm to +5dBm LO Drive
♦ Built-In LO Switch with 43dB LO1-to-LO2 Isolation
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.
