Product Description
This module is intended for 915MHz AMR solutions. It provides a single TDD access
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 27dBm to any internal filtering
before the ANT switch. The LNA section provides a nominal 17dB gain and 1.5dB
noise figure, along with a bypass mode. The device is provided in a 5.5mm x
5.0mm, 28-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 3inch
to 8inch gold over 180inch 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.
