RFFM6901

2.8V to 4.2V, 915MHz ISM Band Transmit/Receive

Module with Diversity Switch

The RFFM6901 is a single-chip front end module (FEM) for application

in the 868MHz and 915MHz ISM Bands. The RFFM6901 addresses the

need for aggressive size reduction for typical portable equipment RF

front end designs and greatly reduces the number of components

outside of the core chipset thus minimizing the footprint and assembly

cost of the overall solution. The RFFM6901 contains an integrated 1W

PA, dual port diversity antenna switch, LNA with bypass mode, and

matching components. The RFFM6901 is packaged in a 32-pin, 6.0mm

x 6.0mm x 1.2mm over-molded laminate package.
