General Description
The MAX9981 evaluation kit (EV kit) simplifies the evalu-
ation of the MAX9981 825MHz to 915MHz dual high-lin-
earity active down-converter mixer. It is fully assembled
and tested at the factory. Standard 50
SMA connec-
tors are included 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) and art-
work for each layer of the PC board.
Contact MaximDirect sales at 888-629-4642 to check
on pricing and availability for these kits.
