Product Description
The RF5385 provides an integrated front-end solution for WiFi 802.11b/g/n and
Bluetooth® systems. The ultra small form factor package and integrated matching
greatly reduces the number of external components and layout area in the cus-
tomer application. This simplifies the total Front-end solution by reducing the bill of
materials, system footprint, and assembly cost.
The RF5385 integrates a 2.4GHz Power Amplifier (PA), 2170MHz notch filter for
coexistence with cellular radios, second harmonic attenuation, power detector cou-
pler for improved accuracy, and a SP3T switch capable of simultaneous reception
for WiFi and Bluetooth®. The device is provided in a 2.5mmx2.5mmx0.5mm, 12-
pin package. This module meets or exceeds the RF Front-end needs of IEEE
802.11b/g/n WiFi RF systems.

Description
Receive port for 802.11b/g/n band. Internally matched to 50. DC block required.
Regulated voltage for the PA bias control circuit. An external bypass capacitor may be needed on the VREG line
for decoupling purposes.
RF input for the 802.11b/g/n PA. Input is matched to 50. DC block required.
PA voltage supply. See applications schematic for biasing and bypassing components.
Same as pin-4.
Power detector voltage for TX section. PDET voltage varies with output power. May need external decoupling.
Port matched to 50. DC block required.
Ground connection.
Bluetooth® RF Port. DC block required.
Control pin for WiFi Receive Port. Please see truth table for proper settings.
Control pin for Bluetooth® Port. Please see truth table for proper settings.
Control pin for WiFi Transmit Port. Please see truth table for proper settings.
Ground connection. The backside of the package should be connected to the ground plane through a short
path, i.e., PCB vias under the device are recommended.
