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, system 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.

Theory of Operation
The RF5765 Front End Module (FEM) is designed for WiFi applications in the 2.5GHz ISM band. It can be applied in many portable applications such as handsets, Portable Media Players, and portable battery power equipment. This highly integrated module can be connected directly to the battery without additional voltage regulators.
WiFi TRANSMIT MODE
The RF5765 requires a single positive supply (V
CC
), a positive supply for switch controls, and a regulated supply for the V
REG
to maintain nominal bias current. The RF5765 transmit path has a typical gain of 30dB from 2.4GHz to 2.5GHz, and delivers
20dBm typical output power under 54Mbps OFDM modulation and 23dBm under 1Mbps 11b modulation. The RF5765 contains basic filter components to produce a bandpass response for the transmit path. Due to space constraints inside the module, filtering is limited to a few resonant poles and additional filters may be required depending upon the end-user’s application. While in transmit mode, the active components are the Power Amplifier (PA) and the TX branch of the SP3T switch.
Refer to the logic control table for proper settings.
TX Biasing Instructions
• Connect the TX input (pin-1) to a signal generator and a spectrum analyzer at the Antenna output (pin-10)
• Set V
CC
to 3.3V with V
REG
set to 0V
• Turn V
REG
ON and set voltage to 3.1V. V
REG
controls the current drawn by the PA and it should quickly reach a quiescent current of approximately 90mA±20mA. Care must be exercised not to exceed 3.5V on the V
REG
pin or the part may be damaged.
• Control bias to the transmit branch of the SP3T switch is tied directly to V
REG
• The SP3T controls for the off branches (C_RX and C_BT) must be set to a logic “low” (0.2V max) or grounded. In the event that one of these branches is left floating or in a logic “high” the performance of the PA will degrade significantly. Likewise, unused RF Ports must be terminated in 50
Ω to simulate actual system conditions and prevent RF signals from coupling back to the PA.
• Turn RF ON
WiFi RECEIVE MODE
Within the frequency band of operation 2.4GHz to 2.5GHz, the RF5765 WiFi receive path has a typical gain of 18dB and a NF of 2.1dB with about 10mA of current. In RX mode, only the RX branch of the SP3T and the LNA are active. Refer to the logic control table for proper settings.
RX Biasing Instructions
• Connect the RX input (ANT/pin-10) to a signal generator and a spectrum analyzer at the RX output (pin-3). A VNA may be used as well.
• Turn the LNA bias ON (pin-4) and set the voltage to 3.3V
• Set C_RX (pin-6) high. This turns ON the receive branch of the SP3T.
• The SP3T controls for the off branches (V
REG
and C_BT) must be set to a logic “low” (0.2V max) or grounded. In the event that one of these branches is left floating or in a logic “high” the performance will degrade. It is recommended to terminate unused RF Ports in 50
Ω.
• Set the control bias for the SPST switch (C_BWRX/pin-5) “low” during WiFi RX only mode.
• Turn RF ON

WiFi and BLUETOOTH
®
RECEIVE (SIMULTANEOUS MODE)
The RF765 WiFi and Bluetooth
®
receive circuits were specifically designed to address issues of simultaneous operation. In this mode both signals can be received at the same time when the C_BWRX (pin-5) is set high. The typical gain for each RF path is approximately 13dB and a NF of 3dB. During simultaneous mode the active components are the LNA, the SPST switch, and only the RX branch of the SP3T. Refer to the logic control table for proper settings.
Simultaneous Mode Biasing Instructions
• Connect the RF input (ANT/pin-10) to a signal generator and a spectrum analyzer at the RX (pin-3) and BT (pin-8) RF ports. A multiport VNA may be used as well.
• Turn the LNA bias ON (pin-4) and set the voltage to 3.3V
• Set C_RX and C_BWRX high. This turns ON the receive branch of the SP3T and the SPST switch.
• The SP3T controls for the off branches (V
REG
and C_BT) must be set to a logic “low” (0.2V max) or grounded. In the event that one of these branches is left floating or in a logic “high” the performance will degrade. It is recommended to terminate unused RF Ports in 50
Ω.
• Turn RF ON
BLUETOOTH
®
MODE
The RF765 Bluetooth
®
only mode is implemented through the SP3T switch by setting C_BT “high.” Typical insertion loss is about 1.2dB.
Bluetooth
®
Biasing Instructions
• Connect the RF input (ANT/pin-10) to a signal generator and a spectrum analyzer at the BT RF port. A VNA may be used in place of the Sig
Gen and SA.
• Set C_BT (pin-9) “high.” This turns the Bluetooth
®
branch of the SP3T switch ON.
• The SP3T controls for the off branches (V
REG
and C_RX) must be set to a logic “low” (0.2V max) or grounded. Do not leave floating.
• Terminate unused RF Ports in 50
Ω
• Turn RF ON
APPLICATION CIRCUIT AND LAYOUT RECOMMENDATIONS
The RF5765 integrates the matching networks and DC blocking capacitors for all RF ports. This greatly reduces the number of external components and layout area needed to implement this FEM. Typically only a total of four external components are required to achieve nominal performance. However, depending on board layout and the many noise signals that could potentially couple to the RF5765, additional bypassing capacitors may be required to properly filter out unwanted signals that might degrade performance.
The LNA bias components consist of an inductor and a decoupling capacitor. The inductor value is critical to optimize NF and return loss at the RX output. For best performance and trade off between critical parameters such as NF, Gain, and IP3, the total inductance including board trace should be approximately 1.2nH. The 5.6k
Ω series resistor for the Bluetooth ®
control line helps to prevent unwanted signal from coupling to this pin. The resistor should be place as close as possible to the package pin. The last component needed in the application circuit is a low frequency bypass capacitor on the V
CC
line. In general, it is good RF practice to have proper decoupling of supply lines to filter out noise. Occasionally, depending on the level of coupling or parasitics of the board, a high frequency bypass capacitor must be added as well.
In order to optimize performance for both the Transmit and Receive paths, a good layout design must be implemented. In addition to designing 50
RF lines, proper grounding along the RF traces and on the FEM ground slug must be exercised. This will minimize coupling and provide good thermal dissipation when the PA is operating at high power. For reference, the RFMD evaluation board uses 9 thermal ground vias (hole/capture pad 12/22mil) on the ground slug. Additionally, if space permitted, V
CC and control lines must be isolated from each other with ground vias in between them. RFMD evaluation board gerbers are available upon request.
