General Description

The MAX2838 evaluation kit (EV kit) simplifies testing of
the MAX2838 receive and transmit performance in
WiMAX™ applications operating in the 3.3GHz to
3.9GHz ISM band. The EV kit provides 50

SMA con-

nectors for all RF and baseband inputs and outputs.
Differential to single-ended and single-ended to differ-
ential line drivers are provided to convert the differential
I/Q baseband inputs and outputs to single ended.
