Product Description
The RF5345 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 match-
ing greatly reduces the number of external components and layout area in the customer appli-
cation. This simplifies the total Front End solution by reducing the bill of materials, system
footprint, and manufacturability cost. The RF5345 integrates a 2.4GHz Power Amplifier (PA),
Low Noise Amplifier (LNA) with bypass mode, power detector coupler for improved accuracy, a
2170MHz notch filter for coexistence with cellular radios, and additional filters for harmonic
rejection. The RF5345 is capable of receiving WiFi and Bluetooth® simultaneously.
The device is provided in a 3.0mmx3.0mmx0.5mm, 16-pin package. This module meets or
exceeds the RF Front End needs of IEEE 802.11b/g/n WiFi RF systems.

RF5345
Pin Function Description
1 LNA BIAS Voltage supply for the LNA. Without LNA Bias “on”, the LNA will be switched into Bypass Mode.
2
RX OUT
Receive port for 802.11b/g/n band. Internally matched to 50. DC block provided.
3
TX IN
RF input for the 802.11b/g/n PA. Input is matched to 50 and DC block is provided.
4
VREG
Regulated voltage for the PA bias control circuit. An external bypass capacitor may be needed on the VREG line for decou-
pling purposes.
5 PDETECT Power detector voltage for TX operation. PDET voltage varies with output power. May need external decoupling.
6
VCC B
Supply voltage for the bias circuit of the PA. Add an external 56pF bypass capacitor for low frequency decoupling.
7
VCC 1
Supply voltage for the first stage of the PA. Add an external 1nF capacitor for low frequency decoupling.
8
N/C
No connect.
9
VCC 2
Supply voltage for the second stage of the PA. Add an external 0.1uF capacitor for low frequency decoupling.
10
GND
Ground.
11
ANT
Antenna port. This pin is internally matched for a 50 load and it is a DC short to ground. See functional block diagram
for more details.
12
C BT
Bluetooth® Mode. BT will always assert this pin when transmitting, or when receiving in BT-only mode. See truth
table for proper settings.
13 BT Bluetooth® RF Port.
14
C TX
Transmit Mode. See truth table for proper settings.
15
C RX
Receive Mode. See truth table for proper settings.
16 C SHARED Shared mode operation between WiFi receive and Bluetooth® receive. Switch acts as a 3dB splitter. See truth
RX table for proper settings.
