Important Notice
Due to the nature of wireless communications, transmission and reception of data can never be
guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant
delays or losses of data are rare when wireless devices such as the Sierra Wireless modem are used
in a normal manner with a well-constructed network, the Sierra Wireless modem should not be used
in situations where failure to transmit or receive data could result in damage of any kind to the user or
any other party, including but not limited to personal injury, death, or loss of property. Sierra Wireless
accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or
received using the Sierra Wireless modem, or for failure of the Sierra Wireless modem to transmit or
receive such data.
Safety and Hazards
Do not operate the Sierra Wireless modem in areas where cellular modems are not advised without
proper device certifications. These areas include environments where cellular radio can interfere such
as explosive atmospheres, medical equipment, or any other equipment which may be susceptible to
any form of radio interference. The Sierra Wireless modem can transmit signals that could interfere
with this equipment. Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is
on the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE POWERED OFF. When
operating, the Sierra Wireless modem can transmit signals that could interfere with various onboard
systems.
Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door
is open. Sierra Wireless modems may be used at this time.
The driver or operator of any vehicle should not operate the Sierra Wireless modem while in control of
a vehicle. Doing so will detract from the driver or operator’s control and operation of that vehicle. In
some states and provinces, operating such communications devices while in control of a vehicle is an
offence.

Measured at the RF connector.
Includes mismatch losses, losses in the
matching circuit, and antenna losses,
excluding cable loss.
Sierra Wireless recommends using
antenna efficiency as the primary
parameter for evaluating the antenna
system.
Peak gain is not a good indication of
antenna performance when integrated with
a host device (the antenna does not
provide omni-directional gain patterns).
Peak gain can be affected by antenna size,
location, design type, etc. — the antenna
gain patterns remain fixed unless one or
more of these parameters change.
Maximum antenna
gain
Must not exceed antenna gains due to
RF exposure and ERP/ EIRP limits,
as listed in the module’s FCC grant.
Isolation between
Ant1 and Ant2 (S21)
> 10 dB
If antennas can be moved, test all
positions for both antennas.
Unless otherwise specified, this
isolation requirement need to be
maintained for optimum operation.
Make sure all other wireless devices
(Bluetooth or WLAN antennas, etc.) are
turned OFF to avoid interference.

Measure power endurance over 4
hours (estimated talk time) using a 2 W
CW signal — set the CW test signal
frequency to the middle of the PCS TX
band (1880 MHz for PCS).
Visually inspect device to ensure there
is no damage to the antenna structure
and matching components.
VSWR / TIS / TRP measurements
taken before and after this test must
show similar results.
* These worst-case VSWR figures for the transmitter bands may not guarantee RSE levels to be within regulatory limits.
The device alone meets all regulatory emissions limits when tested into a cabled (conducted) 50Ω system. With antenna
designs with up to 2.5:1 VSWR or worse, the radiated emissions could exceed limits. The antenna system may need to be
tuned in order to meet the RSE limits as the complex match between the module and antenna can cause unwanted levels
of emissions. Tuning may include antenna pattern changes, phase/delay adjustment, passive component matching.
Examples of the application test limits would be included in FCC Part 22, Part 24 and Part 27, test case 4.2.16 for GSM
(ETSI EN 301 511), and test case 4.2.2 for WCDMA (ETSI EN 301 908-1), where applicable.
a Ant1—Primary, Ant2—Diversity (Diversity/MIMO/)
b Stated band ranges satisfy requirements for both Ant1 and Ant2.
1.4. GNSS
The AirPrime AR758x Series include optional Global Navigation Satellite System (GNSS) capabilities
via the Qualcomm gpsOne Gen8C Engine, capable of operation in assisted and stand-alone modes

3. Routing Constraints and
Recommendations
Layout and routing of the AirPrime AR758x Series in the application is critical to maintaining the
performance of the radio. The following sections provide guidance to the developer when designing
their application to include an AirPrime AR758x Series and achieve optimal system performance.
3.1. RF Routing Recommendations
To route the RF antenna signals, the following recommendations must be observed for PCB layout:
The RF signals must be routed using traces with a 50 characteristic impedance.
Basically, the characteristic impedance depends on the dielectric constant (εr) of the material used,
trace width (W), trace thickness (T), and height (H) between the trace and the reference ground plane.
In order to respect this constraint, Sierra Wireless recommends that a MicroStrip structure be used
and trace width be computed with a simulation tool (such as AppCAD, shown in the figure below and
available free of charge at http://www.avagotech.com).
Figure 1. AppCAD Screenshot for Microstrip Design Power Mode Diagram
The trace width should be wide enough to maintain reasonable insertion loss and manufacturing
reliability. Cutting out inner layers of ground under the trace will increase the effective substrate
height; therefore, increasing the width of the RF trace.
Caution: It is critical that no other signals (digital, analog, or supply) cross under the RF path. The figure
below shows a generic example of good and poor routing techniques.
41110461XXXX Rev 0.1 January 16, 2017 22
Hardware Integration Guide
Routing Constraints and Recommendations
Poor routing
Correct routing
The yellow traces cross the RF trace.
There is no signal around the RF path.
Figure 2. RF Routing Examples
Fill the area around the RF traces with ground and ground vias to connect inner ground layers
for isolation.
Cut out ground fill under RF signal pads to reduce stray capacitance losses.
Avoid routing RF traces with sharp corners. A smooth radius is recommended.
E.g. Use of 45° angles instead of 90°.
The ground reference plane should be a solid continuous plane under the trace.
The coplanar clearance (G, below) from the trace to the ground should be at least the trace
width (W) and at least twice the height (H). This reduces the parasitic capacitance, which
potentially alters the trace impedance and increases the losses.
E.g. If W = 100 microns then G = 200 microns in an ideal setup. G = 150 microns would also
be acceptable is space is limited.
Figure 3. Coplanar Clearance Example
Note: The figure above shows several internal ground layers cut out, which may not be necessary for
every application.

3.2. USB Routing Recommendations
HighSpeed USB signals (USB_D_P / USB_D_M) are a differential pair and must be routed with the
following considerations/constraints:
90 Ohm differential +/- 10% trace impedance,
Differential trace length pair matching < 2mm (15 ps),
Solid reference planes,
Trace lengths < 120 mm,
And 2x the trace width separation to all adjacent signals.
SuperSpeed USB adds two differential pairs (SSRX+ / SSRX- and SSTX+ / SSTX-). These pairs
should be routed with the following considerations/constraints:
90 Ohm differential +/- 15% trace impedance,
Differential trace length pair matching < 0.7mm (5 ps),
Trace lengths < 112 mm,
And GND isolation from other adjacent traces with minimum of 2x the SSRX/SSTX trace
wdith.
3.3. Power and Ground Recommendations
Power and ground routing is critical to achieving optimal performance of the AirPrime AR758x Series
when integrated into an application.
Recommendations:
Do not use a separate GND for the Antennas.
Connections to GND from the AirPrime AR758x Series should be flooded plane using thermal
reliefs to ensure reliable solder joints.
VBATT is recommended to be routed as a wide trace(s) directly from the power supply to the
LGA pad.

Routing Constraints and Recommendations
3.4. Antenna Recommendations
Connecting the antenna ground reference to the vehicle chassis is not recommended since that has
been known to cause noise from the engine to couple into the audio of the device. It is ultimately up to
the integrator to evaluate this performance.
3.5. Interface Circuit Recommendations
The recommended interface implementation is to use a dual-supply bus transceiver with configurable
voltage translation. This allows a host processor operating at a different voltage to communicate with
the AirPrime AR758x Series using the appropriate voltage levels.
The figure below is a reference circuit for a digital input / output signal to / from the AirPrime AR758x
Series.

Figure 5. AirPrime AR758x Series Interface Reference Circuit
The dual-supply bus transceiver with configurable voltage translation used in the reference circuit
above is the Texas Instruments SN74AVC1T45.
If a Digital IO signal is used bidirectional in the application then a bidirectional level translator, such as
Texas Instruments TCA9406 is needed.

5. Approval
5.1. Important Notice
Because of the nature of wireless communications, transmission and reception of data can never be
guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost.
Although significant delays or losses of data are rare when wireless devices such as the Sierra
Wireless modem are used in a normal manner with a well-constructed network, the Sierra Wireless
modem should not be used in situations where failure to transmit or receive data could result in
damage of any kind to the user or any other party, including but not limited to personal injury, death,
or loss of property. Sierra Wireless and its affiliates accept no responsibility for damages of any kind
resulting from delays or errors in data transmitted or received using Sierra Wireless modem, or for
failure of the Sierra Wireless modem to transmit or receive such data.
5.2. Safety and Hazards
Do not operate the AirPrime AR7584:
In areas where blasting is in progress
Where explosive atmospheres may be present including refueling points, fuel depots, and
chemical plants
Near medical equipment, life support equipment, or any equipment which may be susceptible
to any form of radio interference. In such areas, the AirPrime AR7584 device MUST BE
POWERED OFF. Otherwise, the AirPrime AR7584 device can transmit signals that could
interfere with this equipment
In an aircraft, the AirPrime AR7584 device MUST BE POWERED OFF. Otherwise, the
AirPrime AR7584 device can transmit signals that could interfere with various onboard
systems and may be dangerous to the operation of the aircraft or disrupt the cellular network.
Use of cellular phone in aircraft is illegal in some jurisdictions. Failure to observe this
instruction may lead to suspension or denial of cellular telephone services to the offender, or
legal action or both.
Some airlines may permit the use of cellular phones while the aircraft is on the ground and
the door is open. The AirPrime AR7584 device may be used normally at this time.
5.3. Important Compliance Information
The AirPrime AR7584 is granted with a modular approval for mobile applications. Integrators may use
the AR7584 device in their final products without additional FCC certification if they meet the following
conditions. Otherwise, additional FCC approvals must be obtained.
1. The end product must use the RF trace design approved with the AirPrime AR7584 module.
The Gerber file of the trace design can be obtained from Sierra Wireless upon request.
2. At least 20cm separation distance between the antenna and the user’s body must be
