Product Description
The RF5725 is a single-chip integrated front-end module (FEM) for high
performance WiFi applications in the 2.4GHz to 2.5GHz ISM band. This
FEM greatly reduces the number of external components, minimizing foot-
print and assembly cost of the overall 802.11b/g solution. The RF5725
has an integrated b/g power amplifier, LNA, a Coupler Power detector, and
TX filtering. It also is capable of switching between WiFi RX, WiFi TX, and
BTH RX/TX operations. This device is manufactured using GaAs HBT and
pHEMT processes on a 3mmx3mmx0.5mm 16-pin QFN package. This
module meets or exceeds the RF front-end needs of 802.11b/g WiFi RF
systems.

RF5725
Pin Function Description
1 LNA VCC Voltage supply for the LNA (labeled VCC3 on evaluation board).
2
RX OUT
Receive port for 802.11b/g band. Internally matched to 50. DC block provided.
3 TX RF input for the 802.11b/g PA. Input is matched to 50 and DC block is provided.
4
VREG
Regulated voltage for the bias control circuit. An external bypass capacitor may be needed on the VREG line for
decoupling purposes.
5 PDETECT 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.
6
VCC
Supply voltage for the bias circuit of the PA.
7
VCC
Supply voltage for the first stage of the PA. Add an external 0.1uF capacitor for low frequency decoupling.
8
N/C
No connect.
9
VCC
Supply voltage for the second stage of the PA. Add an external 0.1uF capacitor for low frequency decoupling.
10
GND
Ground.
11
ANT
Port matched to 50 and is a DC short to ground.
12
C_BT
Switch control port. See truth table for proper level.
13 BT RF bidirectional port for BluetoothTM. Input is matched to 50 and DC block is provided.
14
C_TX
Switch control port. See switch truth table for proper level.
15
C_RX
Switch control port. See switch truth table for proper level.
16
LNA_EN
LNA enable pin. This is an active high control. A bypass capacitor may be needed for supply noise decoupling.
