MAX2251 Evaluation Kit
General Description
The MAX2251 evaluation kit (EV kit) simplifies evaluation
of the MAX2251 power amplifier (PA), which is designed
for operation in IS-136-based TDMA and AMPS. The kit
enables testing of the device’s RF performance and
requires no additional support circuitry. The EV kit’s signal
input and output use SMA connectors to facilitate the
connection of RF test equipment.
Each kit is assembled with the MAX2251 and incorpo-
rates input and output matching components optimized
for the 824MHz to 849MHz RF frequency band. The EV kit
is capable of operating at RF frequencies from 750MHz to
1000MHz with the appropriate matching components.
Features
o Easy Evaluation of MAX2251
o +2.8V to +4.5V Single-Supply Operation
o RF Input/Output Matched for 824MHz to 849MHz
Operation
o Fully Assembled and Tested
