Product Description
The RFFM3842Q FEM is a single-chip integrated front end module (FEM)
for automotive WiFi. The FEM addresses the need for aggressive size
reduction for a typical 802.11b/g/n front end design and greatly reduces
the number of components outside of the core chipset. The front end
module has integrated b/g/n power amplifier, directional power detector,
Rx balun, and some Tx filtering. It is also capable of switching between
WiFi Rx, WiFi Tx and BTH RX/TX operations. The device is provided in a
3mm x 3mm x 0.45mm, 16-pin package. This module meets or exceeds
the RF front end needs of 802.11b/g/n WiFi RF systems.

Pin Names and Descriptions
Description
RF input for the 802.11b/g/n PA. Input is matched to 50 and DC block is provided.
Ground.
RF bidirectional port for Bluetooth. Input is matched to 50 and DC block is provided.
Digital enable pin for the 802.11b/g/n PA. This is an active high control. An external bypass capacitor may be
needed on the PA EN line for decoupling purposes.
Supply voltage for the 802.11b/g/n PA.
Supply voltage for the 802.11b/g/n PA.
Linearity and Efficiency control pin, please see the Theory of Operation for more information.
Power detector voltage for Tx section. PDET voltage varies with output power. May need external decoupling
capacitor for module stability. May need external circuitry to bring output voltage to desired level.
