General 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 components 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 components.
