MAX2644 Evaluation Kit
General Description
Features
ꢀ Easy Evaluation of MAX2644
The MAX2644 evaluation kit (EV kit) simplifies the evalu-
ation of the MAX2644 low-noise amplifier (LNA). The kit
enables testing of the device’s performance and
requires no additional support circuitry. The signal input
and output use SMA connectors to facilitate easy con-
nection of RF test equipment.
ꢀ +2.7V to +5.5V Single-Supply Operation
ꢀ Matched to 50Ω at 2450MHz
ꢀ Fully Assembled and Tested
The MAX2644 EV kit is fully assembled with the
MAX2644 and incorporates matching components opti-
mized for a 2450MHz RF frequency operation.
