MAX2244/MAX2246 Evaluation Kits
General Description
Features
The MAX2244/MAX2246 evaluation kits (EV kits) simpli-
fy evaluation of the MAX2244/MAX2245/MAX2246
power amplifiers (PAs). They enable testing of the
devices’ RF performance and require no additional
support circuitry. The EV kits’ signal inputs and outputs
use SMA connectors to facilitate the connection of RF
test equipment.
ꢀ Easy Evaluation of the MAX2244/MAX2246
ꢀ 3V to 3.6V Single-Supply Operation
ꢀ Radio-Frequency Output Matched for Operation
from 2.4GHz to 2.5GHz
ꢀ Jumper for Easy Shutdown Control
The MAX2244 EV kit is assembled with a MAX2244 and
incorporates output matching components optimized
for 2.4GHz to 2.5GHz and approximately 22dBm output
power. To evaluate the MAX2245, order samples from
Maxim by calling 1-800-998-8800. The MAX2246 EV kit
is assembled with a MAX2246 and is matched on-
board to provide approximately 20dBm in the 2.4GHz
band.
