RF3858 Datasheet | RF Micro Devices

Features - Integrated LNA, PA and Transfer Switch - Small From Factor 8.0mm x 8.0mm x 1.2mm - 50Ω Inputs and Outputs - Low Insertion Loss, High Isolation Transfer Switch - 31.5d Bm 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 Functional Block Diagram Product Description The RF3858 is a single-chip front-end module (FEM) for applications in the 868MHz/900MHz Band. The RF3858 addresses the need for aggressive size reduction for typical portable equipment RF front-end design and greatly reduces the number of ponents outside of the core chipset thus minimizing the footprint and assembly cost of the overall solution. The RF 3858 contains an integrated 1 Watt PA, TX/RX transfer switch, LNA with bypass mode, and matching ponents. The RF3858 is packaged in a 32-pin, 8.0mm x 8.0mm x 1.2mm over molded laminated package with backside ground which greatly minimizes next level board space and allow for simplified integration .
