RF3858 3.0V to 4.2V ISM Band Transmit/Receive Module with Diversity Transfer Switch
The RF3858 is a single-chip front-end module (FEM) for applications in the 868MHz/900MHz ISM Band. The RF3858 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 RF3858 contains an integrated 1 Watt PA, Tx/Rx transfer switch, LNA with bypass mode, and matching components. The RF3858 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
