MAX2031 Evaluation Kit
General Description
Features
ꢀ Fully Assembled and Tested
The MAX2031 evaluation kit (EV kit) simplifies the evalua-
tion of the MAX2031 WCDMA, cdma2000®, GSM, and
WiMAX(SM) base-station up/downconversion mixer. It is
fully assembled and tested at the factory. Standard 50Ω
SMA connectors are included on the EV kit’s input and
output ports to allow quick and easy evaluation on the
test bench.
ꢀ 50Ω SMA Connectors on Input and Output Ports
ꢀ 815MHz to 1000MHz RF Frequency Range
ꢀ 960MHz to 1180MHz LO Frequency Range
ꢀ DC to 250MHz IF Frequency Range
ꢀ 7dB Conversion Loss
