RFFM5765Q
RFFM5765Q
Tested in Accordance with AEC-Q100
802.11b/g/n WiFi Front End Module
Package: QFN, 16-pin,
3.0mm x 3.0mm x 0.5mm
The RFFM5765Q provides a complete integrated solution in a single
front end module (FEM) for automotive WiFi applications, 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
manufacturing cost. The RFFM5765Q integrates a 2.4GHz power
amplifier (PA), low noise amplifier (LNA), power detector coupler for
improved accuracy, and some filtering for harmonic rejection. The
RFFM5765Q is capable of receiving WiFi and Bluetooth simultaneously
and is tested in accordance with AEC-Q100 standard. The device is
provided in a 3.0mm x 3.0mm x 0.5mm, 16-pin package. This module
meets or exceeds the RF front end needs of IEEE 802.11b/g/n WiFi RF
systems.

RFFM5765Q
Theory of Operation
The RFFM5765Q front end module (FEM) is designed for
automotive 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.
RF ports must be terminated in 50Ω to simulate
actual system conditions and prevent RF signals
from coupling back to the PA.
.
Turn RF ON
WiFi Receive Mode
WiFi Transmit Mode
Within the frequency band of operation 2.4GHz to 2.5GHz,
the RFFM5765Q 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.
The RFFM5765Q requires a single positive supply
(VCC), a positive supply for switch controls, and a
regulated supply for the VREG to maintain nominal bias
current. The RFFM5765Q transmit path has a typical
gain of 30dB from 2.4GHz to 2.5GHz, and delivers
19dBm typical output power under 54Mbps OFDM
modulation and 22dBm under 1Mbps 11b modulation.
The RFFM5765Q 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.
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 (VREG andC_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

.
Connect the Tx input (pin-1) to a signal generator
and a spectrum analyzer at the antenna output

recommended to terminate unused RF ports in 50Ω.
.
.
Set the control bias for the SPST switch (C_BWRX/pin-
5) “low” during WiFi Rx only mode.
.
.
Set VCC to 3.3V with VREGset to 0V
Turn RF ON.
Turn VREG ON and set voltage to 3.1V. VREG
controls the current drawn by the PA and it should
quickly reach a quiescent current of approximately
110mA ± 20mA. Care must be exercised not to
exceed 3.5V on the VREG pin or the part may be
damaged.
WiFi and Bluetooth Receive
(Simultaneous Mode)
The RFFM5765Q 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

Control bias to the transmit branch of the SP3T
switch is tied directly to VREG
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

SP3T. Refer to the logic control table for proper
settings.
Application Circuit and Layout
Recommendations
The RFFM5765Q 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 RFFM5765Q,
additional bypassing capacitors may be required to
properly filter out unwanted signals that might degrade
performance.
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 (VREG 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 50Ω.
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 tradeoff between critical parameters
such as NF, Gain, and IP3, the total inductance
including board trace should be approximately 1.2nH.
The 5.6kΩ 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 VCC 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.
.
Turn RF ON.
Bluetooth Mode
The RFFM5765Q 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.
In order to optimize performance for both the transmit
and receive paths, a good layout design must be
implemented. In addition to designing 50Ω 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, VCC and control lines
must be isolated from each other with ground vias in
between them. RFMD evaluation board gerbers are
available upon request.
.
.
Set C_BT (pin-9) “high.” This turns the Bluetooth
branch of the SP3T switch ON.
The SP3T controls for the off branches (VREG and
C_RX) must be set to a logic “low” (0.2V max) or
grounded. Do not leave floating.
.
.
Terminate unused RF Ports in 50Ω.
Turn RF ON
