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

915MHz ISM Band. The RFFM6901 addresses the need for aggressive size reduc-

tion 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.
