Product Description
The RF5765 provides a complete integrated solution in a single Front End
Module (FEM) for WiFi 802.11b/g/n and Bluetooth® systems. The ultra
small form factor and integrated matching greatly reduces the number of
external components and layout area in the customer application. This
simplifies the total Front End solution by reducing the bill of materials, sys-
tem footprint, and manufacturability cost. The RF5765 integrates a
2.4GHz Power Amplifier (PA), Low Noise Amplifier (LNA), power detector
coupler for improved accuracy, and some filtering for harmonic rejection.
The RF5765 is capable of receiving WiFi and Bluetooth® simultaneously.
The device is provided in a 3mmx3mmx0.5mm, 16-pin package. This
module meets or exceeds the RF Front End needs of IEEE 802.11b/g/n
WiFi RF systems.

Pin Function Description
1
TX_IN
RF input for the 802.11b/g PA. Input is matched to 50and DC block is provided.
2
VREG
Regulated voltage for the bias control circuit, and the TX control port of the SP3T which is also tied to this pin. An
external bypass capacitor may be needed on the VREG line for decoupling purposes.
3
RX OUT
Receive port for 802.11b/g band. Internally matched to 50. DC block provided.
4 LNA VDD Voltage supply for the LNA.
5 C_BWRX SPST switch control pin. (Simultaneous WiFi and BT receive.) See truth table for proper level.
6
C RX
Receive switch control pin. See switch truth table for proper level.
7
N/C
No connect.
8 BT RF bidirectional port for Bluetooth®. Input is matched to 50and DC block is provided.
9
C_BT
Bluetooth® switch control pin. See truth table for proper level.
10
ANT
Port matched to 50and is DC blocked internally.
11
GND
Ground.
12
N/C
No connect.
13
N/C
No connect.
14
VCC
Supply voltage for the PA.
15
VCC
Supply voltage for the bias circuit of the PA.
16 PDETECT Power detector voltage for TX section. PDET voltage varies with output power. May need external decoupling
capacitor for noise bypassing. May need external circuitry to bring output voltage to desired level.
