3.4.2 WAKE# Signal
WAKE# signal supports software control.
This signal is used for module to wake up the host. It is designed as an OC (Open
Collector) gate, so it should be pulled up by the host and it is active-low.
When the module wakes up the host, the WAKE# pin will output low-level-voltage for
1s to wake up the host.

3.4.3 RESIN_N Signal
The RESIN_N signal is used to reset the module's system. When the module software
stops responding, the RESIN_N pin can be pulled down to reset the module
hardware.
The RESIN_N signal is internally pulled up to 1.8 V, and it turns on automatically when
the VCC_3V3 is pulled up. The RESIN_N signal is active-low.

- As the RESIN_N signal is relatively sensitive, it is recommended that you install a
10 nF–0.1 µF capacitor near the RESIN_N pin of the interface for filtering. In
addition, when you design a circuit on the PCB of the interface board, it is
recommended that the circuit length should not exceed 20 mm and that the circuit
should be kept at a distance of 2.54 mm (100 mil) at least from the PCB edge.
Furthermore, you need to wrap the area adjacent to the signal wire with a ground
wire. Otherwise, the module may be reset due to interference.
- The maximum Forward Voltage Drop of the diode used in the module is 0.6 V. So
when the host wants to reset the module, the low-level-voltage in the RESIN_N pin
should be below 50 mV.
The MU709 module supports hardware reset function. If the software of the MU709
module stops responding, you can reset the hardware through the RESIN_N signal as
shown in Figure 3-6 . When a low-level pulse is supplied through the RESIN_N pin,
the hardware will be reset. After the hardware is reset, the software starts powering on
the module and reports relevant information according to the actual settings. For
example, the AT command automatically reports ^SYSSTART.

- The RESIN_N pin must not be pulled down for more than 1s.
- The RESIN_N pin is optional, which can not be connected.

3.6.2 Circuit Recommended for the USIM Card Interface
As the Mini PCIe Adapter is not equipped with a USIM socket, you need to place a
USIM socket on the user interface board. Figure 3-9 shows the circuit of the USIM
card interface.
Figure 3-9 Circuit of the USIM card interface
- To meet the requirements of 3GPP TS 51.010-1 protocols and electromagnetic
compatibility (EMC) authentication, the USIM socket should be placed near the
PCIe interface (it is recommended that the PCB circuit connects the PCIe interface
and the USIM socket does not exceed 100 mm), because a long circuit may lead to
wave distortion, thus affecting signal quality.
- It is recommended that you wrap the area adjacent to the USIM_CLK and
USIM_DATA signal wires with ground. The Ground pin of the USIM socket and the
Ground pin of the USIM card must be well connected to the power Ground pin
supplying power to the PCIe Adapter.
- A 100 nF capacitor and1 μF capacitor are placed between the USIM_PWR and
Ground pins in a parallel manner (If USIM_PWR circuit is too long, that the larger
capacitance such as 4.7 μF can be employed if necessary). Three 33 pF

capacitors are placed between the USIM_DATA and Ground pins, the
USIM_RESET and Ground pins, and the USIM_CLK and Ground pins in parallel to
filter interference from RF signals.
- It is recommended to take electrostatic discharge (ESD) protection measures near
the USIM card socket. The TVS diode with Vrwm of 5 V and junction capacitance
less than 10 pF must be placed as close as possible to the USIM socket, and the
Ground pin of the ESD protection component is well connected to the power
Ground pin that supplies power to the PCIe Adapter.

4.5 Antenna Design Requirements
4.5.1 Antenna Design Indicators
Antenna Efficiency
Antenna efficiency is the ratio of the input power to the radiated or received power of
an antenna. The radiated power of an antenna is always lower than the input power
due to the following antenna losses: return loss, material loss, and coupling loss. The
efficiency of an antenna relates to its electrical dimensions. To be specific, the
antenna efficiency increases with the electrical dimensions. In addition, the
transmission cable from the antenna connector of PCIe Adapter to the antenna is also
part of the antenna. The cable loss increases with the cable length and the frequency.

31
It is recommended that the cable loss is as low as possible, for example, U.FL-LP-088
made by HRS.
The following antenna efficiency (free space) is recommended for MU709 module to
ensure high radio performance of the module:
- Efficiency of the primary antenna: ≥ 40% (below 960 MHz); ≥ 50% (over 1710
MHz)
- Efficiency of the diversity antenna: ≥ half of the efficiency of the primary
antenna in receiving band
In addition, the efficiency should be tested with the transmission cable.
S11 or VSWR
S11 indicates the degree to which the input impedance of an antenna matches the
reference impedance (50 Ω). S11 shows the resonance feature and impedance
bandwidth of an antenna. Voltage standing wave ratio (VSWR) is another expression
of S11. S11 relates to the antenna efficiency. S11 can be measured with a vector
analyzer.
The following S11 value is recommended for the antenna of MU709 module:
- S11 of the primary antenna: ≤ –6 dB
- S11 of the diversity antenna: ≤ –6 dB
In addition, S11 is less important than the efficiency, and S11 has weak correlation to
wireless performance.
Isolation
For a wireless device with multiple antennas, the power of different antennas is
coupled with each other. Antenna isolation is used to measure the power coupling.
The power radiated by an antenna might be received by an adjacent antenna, which
decreases the antenna radiation efficiency and affects the running of other devices. To
avoid this problem, evaluate the antenna isolation as sufficiently as possible at the
early stage of antenna design.
Antenna isolation depends on the following factors:
- Distance between antennas
- Antenna type
- Antenna direction
The primary antenna must be placed as near as possible to the MU709 module to
minimize the cable length. The diversity antenna needs to be installed
perpendicularly to the primary antenna. The diversity antenna can be placed farther
away from the MU709 module. Antenna isolation can be measured with a two-port
vector network analyzer.
The following antenna isolation is recommended for the antennas on laptops:
- Isolation between the primary and diversity antennas: ≤ –12 dB
- Isolation between the primary antenna and the Wi-Fi antenna: ≤ –15 dB

Polarization
The polarization of an antenna is the orientation of the electric field vector that rotates
with time in the direction of maximum radiation.
The linear polarization is recommended for the antenna of MU709 module.
Radiation Pattern
The radiation pattern of an antenna reflects the radiation features of the antenna in the
remote field region. The radiation pattern of an antenna commonly describes the
power or field strength of the radiated electromagnetic waves in various directions
from the antenna. The power or field strength varies with the angular coordinates (θ
and φ), but is independent of the radial coordinates.
The radiation pattern of half wave dipole antennas is omnidirectional in the horizontal
plane, and the incident waves of base stations are often in the horizontal plane. For
this reason, the receiving performance is optimal.
The following radiation patterns are recommended for the antenna of MU709 module.
Primary/Diversity antenna: omnidirectional
In addition, the diversity antenna's pattern should be complementary with the
primary's.
Envelope Correlation Coefficient
The envelope correlation coefficient indicates the correlation between different
antennas in a multi-antenna system (primary antenna, diversity antenna, and MIMO
antenna). The correlation coefficient shows the similarity of radiation patterns, that is,
amplitude and phase, of the antennas. The ideal correlation coefficient of a diversity
antenna system or a MIMO antenna system is 0. A small value of the envelope
correlation coefficient between the primary antenna and the diversity antenna
indicates a high diversity gain. The envelope correlation coefficient depends on the
following factors:
- Distance between antennas
- Antenna type
- Antenna direction
The antenna correlation coefficient differs from the antenna isolation. Sufficient
antenna isolation does not represent a satisfactory correlation coefficient. For this
reason, the two indicators need to be evaluated separately.
For the antennas on laptops, the recommended envelope correlation coefficient
between the primary antenna and the diversity antenna is smaller than 0.5.
Gain and Directivity
The radiation pattern of an antenna represents the field strength of the radiated
electromagnetic waves in all directions, but not the power density that the antenna
radiates in the specific direction. The directivity of an antenna, however, measures the
power density that the antenna radiates.

Gain, as another important parameter of antennas, correlates closely to the directivity.
The gain of an antenna takes both the directivity and the efficiency of the antenna into
account. The appropriate antenna gain prolongs the service life of relevant batteries.
The following antenna gain is recommended for MU709 module. Gain of the
primary/diversity antenna ≤ 2.5 dBi
- The antenna consists of the antenna body and the relevant RF transmission cable. Take the
RF transmission cable into account when measuring any of the preceding antenna
indicators.
- Huawei cooperates with various famous antenna suppliers who are able to make
suggestions on antenna design, for example, Amphenol, Skycross, etc.
4.5.2 Interference
Besides the antenna performance, the interference on the user board also affects the
radio performance (especially the TIS) of the module. To guarantee high performance
of the module, the interference sources on the user board must be properly controlled.
On the user board, there are various interference sources, such as the LCD, CPU,
audio circuits, and power supply. All the interference sources emit interference signals
that affect the normal operation of the module. For example, the module sensitivity
can be decreased due to interference signals. Therefore, during the design, you need
to consider how to reduce the effects of interference sources on the module. You can
take the following measures: Use a LCD with optimized performance; shield the LCD
interference signals; shield the signal cable of the board; or design filter circuits.
Huawei is able to make technical suggestions on radio performance improvement of
the module.

5.6 EMC and ESD Features
The following are the EMC design comments:
- Attention should be paid to static control in the manufacture, assembly, packaging,
handling, storage process to reduce electrostatic damage to HUAWEI module.
- RSE (Radiated Spurious Emission) may exceed the limit defined by EN301489 if
the antenna port is protected by TVS (Transient Voltage Suppressor), which is
resolved by making some adjustment on RF match circuit.
- TVS should be added on the USB port for ESD protection, and the parasitic
capacitance of TVS on D+/D- signal should be less than 2 pF. Common-mode
inductor should be added in parallel on D+/D- signal.
- TVS should be added on the USIM interface for ESD protection. The parasitic
capacitance of TVS on USIM signal should be less than 10 pF.
- Resistors in parallel and a 10 nF capacitor should be added on RESIN_N signal
to avoid shaking, and the distance between the capacitor and the related pin
should be less than 100 mil.
- PCB routing should be V-type rather than T-type for TVS.
- An integrated ground plane is necessary for EMC design.
The following are the requirements of ESD environment control:
- The electrostatic discharge protected area (EPA) must have an ESD floor whose
surface resistance and system resistance are greater than 1 x 104 Ω while less
than 1 x 109 Ω.
- The EPA must have a sound ground system without loose ground wires, and the
ground resistance must be less than 4 Ω.
- The workbench for handling ESD sensitive components must be equipped with
common ground points, the wrist strap jack, and ESD pad. The resistance
between the jack and common ground point must be less than 4 Ω. The surface
resistance and system resistance of the ESD pad must be less than 1 x 109 Ω.

− 1 x 105 Ω ≤ ICT fixture soft ground resistance < 1 x 1011 Ω
− The electronic screwdriver and electronic soldering iron can be easily oxidized.
Their ground resistance must be less than 20 Ω.
- The parts of the equipment, devices, and tools that touch the ESD sensitive
components and moving parts that are close to the ESD sensitive components
must be made of ESD materials and have sound ground connection. The parts
that are not made of ESD materials must be handled with ESD treatment, such
as painting the ESD coating or ionization treatment (check that the friction voltage
is less than 100 V).
- Key parts in the production equipment (parts that touch the ESD sensitive
components or parts that are within 30 cm away from the ESD sensitive
components), including the conveyor belt, conveyor chain, guide wheel, and SMT
nozzle, must all be made of ESD materials and be connected to the ground
properly (check that the friction voltage is less than 100 V).
- Engineers that touch IC chips, boards, modules, and other ESD sensitive
components and assemblies must wear ESD wrist straps, ESD gloves, or ESD
finger cots properly. Engineers that sit when handling the components must all
wear ESD wrist straps.
- Noticeable ESD warning signs must be attached to the packages and placement
areas of ESD sensitive components and assemblies.
- Boards and IC chips must not be stacked randomly or be placed with other ESD
components.
- Effective shielding measures must be taken on the ESD sensitive materials that
are transported or stored outside the EPA.

6.7 Thermal Design Guide
When using in the network, the MU709 module (Mini PCIe) have high power
consumption. To improve the module reliability and stability, focus on the thermal
design of the device to speed up heat dissipation.
Take the following heat dissipation measures:
- Do not hollow out the customer PCB.
- Attach the thermal conductive material between the Mini PCIe and the customer
PCB. The recommended thermal conductivity of the thermal conductive material
is 1.0 W/m-k or higher (recommended manufacturers: Laird and Bergquist). The

54
dimensions (W x D) of the thermal conductive material are 38 mm x 28 mm (1.50
in. x 1.10 in.), and its height depends on the height of the Mini PCIe connector
you use and the method for installing the Mini PCIe. When deciding the height of
the thermal conductive material, you are advised to obey the following rule: After
the Mini PCIe is fastened to the customer PCB, the compression amount of the
thermal conductive material accounts for 15% to 30% of the thermal conductive
material size. For example, if you use a connector shown in the following figure
and install the Mini PCIe like this, the recommended height of the thermal
conductive material is 1.8 mm (0.07 in.).
- On the customer PCB, reserve two metal screw holes, which are connected to
the PCB ground plane. When installing the Mini PCIe, use two metal screws to
fasten the Mini PCIe to the customer PCB. See the following figure.
- Ensure that the air flow around the Mini PCIe is sufficient.
- Try not to place any component in the Mini PCIe's projection region on the
customer PCB. Do not place components with 1.5 W or higher power
consumption or heat sensitive components (such as crystals) near the Mini PCIe.
- Use a large customer PCB. The recommended size (W x D) is 70 mm x 70 mm
(2.76 in. x 2.76 in.).
- If the thermal conductive material is attached between the Mini PCIe and the
customer PCB, then the heat dissipation performance will be better for multilayer
PCB.
- Apply copper to the region for attaching the thermal conductive material to the
customer PCB. Try to use the continuous ground plane design on the customer
PCB, and each ground plane must be connected through holes. Therefore,
reserve holes as many as possible.

If you do not take the preceding heat dissipation measures, the overheat protection mechanism
is triggered due to overheated Mini PCIe and the network connection is terminated when the
Mini PCIe keeps working in enclosed space with a 70ºC temperature and a big current for a
period of time. You can resume the network connection only after the temperature drops.
