RFMD + TriQuint = Qorvo RFFM6901 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.
