Datasheet

RFMD’s new RFFM6904 is a single-chip front-end module for applications in the 868MHz/900MHz ISM Band. The RFFM6904 addresses the need for aggressive size reduction for typical portable equipment RF front-end design and greatly reduces the number of components outside of the core chipset, thus minimizing the footprint and assembly cost of the overall solution.

The RFFM6904 contains an integrated 2W PA, Tx/Rx transfer switch, LNA with bypass mode, and matching components. The RFFM6904 is packaged in a 32-pin, 8.0mm x 8.0mm x 1.2mm overmolded laminate package with backside ground which greatly minimizes next level board space and allows for simplified integration.

Features:
• Integrated LNA, PA, and Transfer Switch
• Small Form Factor 8.0mm x 8.0mm x 1.2mm
• 50Ω Inputs and Outputs
• Low Insertion Loss, High Isolation Transfer Switch
• 33.5dBm PA Output Power
• Low PA Harmonic Content

Applications:
• 868MHz/900MHz ISM Band Application
• Single Chip RF Front End Module
• Portable Battery Powered Equipment
• Wireless Automatic Metering Applications

This device is currently available in production quantities. Pricing begins at $5.70 each for 100 pieces.
