Product Description  
Smart Energy  
This module is intended for 915MHz AMR solutions. It provides separate ports for  
Rx and Tx paths and two ports on the output for connecting a diversity solution or a  
test port. The PA section provides a nominal output power of 28dBm. The device is  
provided in a 6mm x 6mm, 32-pin package.

PCB Design Requirements  
PCB Surface Finish  
The PCB surface finish used for RFMD's qualification process is electroless nickel, immersion gold. Typical thickness is 3inch  
to 8inch gold over 180inch nickel.  
PCB Land Pattern Recommendation  
PCB land patterns for RFMD components are based on IPC-7351 standards and RFMD empirical data. The pad pattern shown  
has been developed and tested for optimized assembly at RFMD. The PCB land pattern has been developed to accommodate  
lead and package tolerances. Since surface mount processes vary from company to company, careful process development is  
recommended.
