Product Description
The RFFM3482E is a single-chip integrated front end module (FEM) for
high-performance WiFi applications in the 2.4GHz to 2.5GHz ISM band.
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 compo-
nents outside of the core chipset. The FEM 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 opera-
tions. The device is provided in a 3mmx3mmx0.45mm, 16-pin package.
This module meets or exceeds the RF front end needs of 802.11b/g/n
WiFi RF systems.

RFFM3482E Biasing Instructions:
• 802.11b/g/n Transmit (VB compliance=5.5V, 400mA, PA EN compliance=2V, ~450A)
• Connect the FEM to a signal generator at the input and a spectrum analyzer at the output.
• Bias VB to 3.6V first with PA_EN=0.0V
• Refer to switch operational truth table to set the control lines at the proper levels for WiFi Tx.
• Turn on PA_EN to 1.8V (typ.). Be extremely careful not to exceed 3.0V on the PA_EN pin, or the part may exceed device cur-
rent limits.
• Turn on PABC to 1.5mA (or 0.6V). For 11b operation Adjust PABC to 1.8mA. This controls the current drawn by the
802.11b/g/n power amplifier and the idle current should rise to ~115mA±20mA for a typical part, but it varies based on the
output power desired.
• 802.11 b/g/n Receive
• To Receive WiFi set the switch control lines per the truth table below.
• Bluetooth Receive
To Receive Bluetooth set the switch control lines per the truth table below.
