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.
