MAX2642/MAX2643 Evaluation Kits
General Description
Features
The MAX2642/MAX2643 evaluation kits (EV kits) simplify
evaluation of the MAX2642 and MAX2643 low-noise
amplifiers (LNAs). These kits enable testing of the
devices’ performance and require no additional support
circuitry. The signal input and output use SMA connectors
to facilitate connection of RF test equipment.
ꢀ Easy Evaluation of MAX2642/MAX2643
ꢀ +2.7V to +5.5V Single-Supply Operation
ꢀ RF Input and Output Matched to 50Ω at 900MHz
ꢀ Jumper Included for Gain/Shutdown Setting
ꢀ Fully Assembled and Tested
The MAX2642/MAX2643 EV kits are fully assembled
with the MAX2642 or MAX2643 on board, and incorporate
input matching components optimized for 900MHz
operation.
