Product Description
The RF6545 integrates a complete solution in a single Front End Module (FEM) for
Smart Meters for Energy
Management
WiFi and ZigBee® applications in the 2.4GHz to 2.5GHz band. This FEM integrates
the PA plus harmonic filter in the transmit path. It provides a single balanced TDD
access for Rx and Tx paths along with two ports on the output for connecting a
diversity solution or a test port. The device is provided in a 3.5mm x 3.5mm x
0.5mm, 20 pin QFN 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.
PCB Metal Land and Solder Mask Pattern
Thermal vias for center slug “C” should be incorporated into the PCB design. The number and size of thermal vias will depend
on the application, the power dissipation, and this electrical requirements. Example of the number and size of vias can be
found on the RFMD evaluation board layout.
