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 blasting is in progress,
where explosive atmospheres may be present, near medical equipment, near life
support equipment, or any equipment which may be susceptible to any form of
radio interference. In such areas, the Sierra Wireless modem MUST BE
POWERED OFF. 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.

2: Power
Power Supply
The host provides power to the AirPrime WP8548 through multiple power and
ground pins. The host must provide safe and continuous power at all times; the
module does not have an independent power supply, or protection circuits to
guard against electrical issues.
For detailed pinout and voltage / current requirements of this module, see the
AirPrime WP8548 Product Technical Specification.
Module Power States
The module has three main power states, as described in Table 2-1.

4: Routing Constraints and Recommendations
This section describes general routing constraints and recommendations for the
AirPrime WP8548 module.
Note: This is a non-exhaustive list of suggested design guidelines. The developer is
responsible for deciding whether to implement these guidelines.
General Rules and Recommendations
Clock and other high-frequency digital signals (e.g. serial buses) should be routed
as far as possible from the module’s analog signals.
If the application design makes it possible, all analog signals should be separated
from digital signals by a ground trace on the PCB.
Tip: Avoid routing any signals under the module on the application board.
PCB Layout Recommendations
Ground pads should be re-flowed on to the host PCB with < 30% voiding to allow
effective heat dissipation.
Power Supply
When designing the power supply, make sure that VBAT_BB / VBAT_RF meet the
requirements listed in the WP8548 Product Technical Specification.
Careful attention should be paid to the following:
Rev 2 Feb.16
•
Power supply quality — PFM, or PSM systems should be avoided; Low ripple,
linear regulation or PWM converters are preferred for low noise.
•
Capacity to deliver high current peaks in a short time (for pulsed radio
emission)
•
VBAT_BB / VBAT_RF must support peak currents with an acceptable voltage
drop that guarantees the minimum required VBAT_BB / VBAT_RF value.
•
VBAT_BB / VBAT_RF signal pads must never exceed the maximum required
VBAT_BB / VBAT_RF value, otherwise the module’s power amplifier and GPS
chipset may be severely damaged.
•
A weakly-designed (not robust) power supply could affect EMC performance,
the emission spectrum, and the phase error and frequency error.

Specifications subject to change
Hardware Integration Guide
Antenna
Sierra Wireless strongly recommends working with an antenna manufacturer
either to develop an antenna adapted to the application, or to adapt an existing
solution to the application.
For information on routing constraints for the RF circuit, see RF Circuit on
page 15.
PCB Specifications for the Application
Board
Sensitive signals (such as audio, UIM, and clocks) should be protected by ground
planes / fills. Routing sensitive signals close to noisy signals could result in noise
being coupled.
Recommended PCB Land Pattern
Refer to the AirPrime WP8548 Customer Process Guidelines document, available
at http://source.sierrawireless.com.
Routing Constraints
Power Supply
If the following design recommendations are not followed, phase error (peak) and
power loss could occur.
•
Since the maximum peak current can reach 2.5 A, Sierra Wireless strongly
recommends having a large width for the layout of the power supply signal (to
avoid voltage loss between the external power supply and VBAT_BB /
VBAT_RF.
Figure 4-1: Power Supply Routing Example
Specifications subject to change
14
4118723
Routing Constraints and Recommendations
Note: Figure 4-1 shows separate traces for VBAT_BB and VBAT_RF. If VBAT_BB and
VBAT_RF share a single power supply, these traces should be connected.
Note: For optimal decoupling, place the capacitors on the underside of the board, directly
under the pins.
•
Filtering capacitors (100 nF to 1500 F) are recommended near the module’s
power supply.
•
Attention should be paid to the ground trace or the ground plane on the application board for the power supply that supplies the module. The ground trace
or ground plane, as well as the VBAT trace, must be able to support current
peaks.
•
If the ground trace between the module and the power supply is a copper
plane, make sure it is a solid plane.
•
Design routing to make sure total line impedance does not exceed
10 m @ 217 Hz.
Ground Plane Connection
The AirPrime WP8548 module requires a solid, central ground plane (with solder
mask defined pads) located directly under the module. This will:
•
Ensure high current signal returns
•
Provide heat dissipation under higher operating temperatures
The ground plane should be connected (with vias) to the reference ground layer
of the application board.
UIM Interface
•
The length of the tracks between the AirPrime WP8548 and the UIM socket
should be as short as possible. Maximum recommended length is 10cm.
•
ESD protection is mandatory on the UIM lines unless:
· An ESIM is being used, or
· There is no physical access to the UIM
•
The decoupling capacitor(s) should be placed as close as possible to the UIM
card connector for the UIM1_VCC signal.
RF Circuit
The RF signal must be routed on the application board using tracks with a 50
characteristic impedance.
The characteristic impedance depends on the dielectric, the track width and the
ground plane spacing.
Rev 2 Feb.16
15
Specifications subject to change
Hardware Integration Guide
It is recommended to use stripline design if the RF path is fairly long (more than
3cm), since microstrip design is not shielded. Consequently, the RF (transmit)
signal may interfere with neighboring electronic circuits. In the same way, the
neighboring electronics (micro-controllers, etc.) may interfere with the RF
(receive) signal and degrade the reception performance.
USB Interface
When the USB interface is externally accessible, ESD protection is required on
the USB_VBUS, USB_D+, and USB_D- signals.
Thermal Considerations
When transmitting, the AirPrime WP8548 can generate significant amounts of
heat (due to the internal Power Amplifier) that must be dissipated in the host
device for safety and performance reasons.
The amount of thermal dissipation required depends on the following factors:
•
Supply voltage — Maximum power dissipation for these modules can be up to
3 W at voltage supply limits.
•
Usage — Typical power dissipation values depend on the location within the
host, amount of data transferred, etc.
To enhance heat dissipation:
•
Maximize airflow over / around the module
•
Locate the module away from other components that generate heat
•
Ensure the module is connected to a solid ground plane
EMC and ESD Recommendations
EMC tests must be performed on the application as soon as possible to detect
any potential problems.
When designing, special attention should be paid to:
•
Possible spurious emissions radiated by the application to the RF receiver in
the receiver band
•
ESD protection — Typically, ESD protection is mandatory for externally accessible signals, including:
· VBAT_RF / VBAT_BB
· UIM (if accessible from outside)
· Serial link
· USB
· Antennas
•
Length of the UIM interface lines (preferably <10 cm)
•
Length of the HSIC interface lines (<10 cm, as required by the HSIC specification)
•
EMC protection on audio input/output (filters against 900 MHz emissions)

Routing Constraints and Recommendations
•
Ground plane: Sierra Wireless recommends a common ground plane for
analog/digital/RF grounds
Note: The AirPrime WP8548 does not include any protection against over-voltage.
The host device must provide adequate ESD protection on digital circuits and
antenna ports as detailed in the following table.
Note: The level of protection required depends on your application.
