AirPrime Embedded Module Hardware Integration Guide
Note: An understanding of
network technology, and
experience in integrating
hardware components into
electronic equipment is
assumed.
Purpose of this guide
This guide addresses issues that affect the integration of AirPrime embedded
modules into host products, and includes design recommendations for the host
products.
The Universal Development Kit
Sierra Wireless manufactures a Universal Development Kit (UDK) that facilitates
all phases of the integration process.
This kit is a hardware development platform that is designed to support the
AirPrime embedded modules listed in Table 1-1 on page 7. It contains the
hardware components that are typically necessary for evaluating and developing
with the module, including:
•
Development board
•
Cables
•
Antennas
•
Other accessories
For instructions on setting up the UDK, see PCI Express Mini Card Dev Kit Quick
Start Guide (Document 2130705).
Required connectors
Note: Contact vendors
before choosing your
connectors—the numbers
included here are for
reference only. Choose
connectors that are appropriate to your design.
When integrating AirPrime embedded modules into your host device, you need
the following connector types:
•
RF cables that mate with Hirose U.FL connectors (model
U.FL #CL331-0471-0-10). Modules include one to three connector jacks
depending on individual module support for diversity or GPS functionality.
•
Industry-standard mating connector for 52-pin EDGE—some manufacturers
include Tyco, Foxconn, and Molex. For example, the connector used on the
Mini Card Dev Kit board is a Molex 67910-0001.
•
Industry-standard USIM connector (MC8xxx only)—the actual connector you
use depends on how your device exposes the USIM socket. For example, the
USIM connector used on the Mini Card Dev Kit board is an ITT CCM03-3518.

2: Power Interface
Overview of operation
Note: This chapter contains information for both CDMA (MC57xx) and GSM
(MC8xxx) AirPrime embedded modules.
Information that is unique to specific module types is clearly identified.
AirPrime embedded modules are designed to use a 3.3V (nominal)
power supply (3.8V for the MC8201) provided by the host. It is the
host’s responsibility to provide safe and continuous power to the
module at all times; the module does NOT have an independent
power supply, or protection circuits to guard against electrical issues.
The module’s power state is controlled by the host’s assertion/deassertion of the W_Disable# signal. The module also monitors its
supply voltage and requests shutdown if the supply is insufficient.
Power signals
The module must be connected to a 3.3V power supply (3.8V for the
MC8201), as described in PCI Express Mini Card Electromechanical
Specification Revision 1.1.
The MC8xxx has more power pins than the MC57xx due to higher
peak current requirements for GSM devices.
For detailed pinout and voltage/current requirements of these
modules, see the Product Specification Document for your AirPrime
embedded module (see Table 1-2 on page 9).
Electrostatic discharge (ESD)
You are responsible for ensuring that the host has adequate ESD
protection on digital circuits and antenna ports as described by the
following specifications:
Rev 2.02 Sep.10
•
(Operational) RF port (antenna launch and RF connector): IEC61000-4-2—Level (Electrostatic Discharge Immunity Test)
•
(Non-operational) Host connector interface: JESD22-A114-B +/1kV Human Body Model and JESD22-C101 +/- 125 V Charged
Device Model
•
MC5728V only: (Non-operational) Host connector interface:
JESD22-A114-B +/- 125V Human Body Model and
JESD22-C101 +/- 100 V Charged Device Model
MC5728V has placeholders for additional ESD devices, for
cases where the device must, per customer requirements, meet
the higher Human Body Model (+/-1kV) ESD rating.
Proprietary and Confidential
13
AirPrime Embedded Module Hardware Integration Guide
This guide provides specific recommendations where needed, however, the level
of protection required depends on your application.
Note: ESD protection is highly recommended for the USIM connector at the point where
the contacts are exposed, and for any other signals from the host interface that would be
subjected to ESD by the user of the product.
Module power states
Note: The module unit
defaults to the Normal
state when VCC is first
applied in the absence of
W_Disable# control.
The module has four power states:
•
Disconnected
No power to the module.
•
Off
Power to the module, but the module is powered off.
•
Normal
The module is active. Several modes are possible (Receive, Transmit, Sleep,
Shutdown).
•
Low power (“airplane mode”)
The module is active, but RF is disabled.
State machines are implemented in the module to monitor the power supply and
operating temperature.
Disconnected state
Note: The difference
between the Disconnected and Off states is
that, in the Off state, the
module is still connected to
the power source and
draws minimal current.
This state occurs when there is no power to the module—the host power source
is disconnected from the module and all voltages associated with the module are
at 0 V.
Whether the host device is also powered off depends on the power rail design:
•
If the connection between the power rail and the module is controlled by the
host, the host can stay powered on and cut the power to put the module into
the disconnected state.
•
If the power rail is shared between the host device and the module, the host
is powered off when the module is powered off.
Off state
In this state, the host is powered up and the module is powered down (but still
connected to the power source).
The host keeps the module powered off by driving the W_Disable# signal low. In
this state, the module draws minimal current.
14
Proprietary and Confidential
2130114
Power Interface
Note: This is the default
state when VCC is first
applied in the absence of
W_Disable# control.
Normal state
This is the active state of the module. In this state:
•
The module is fully powered.
•
The module is capable of placing/receiving calls or establishing data connections on the wireless network.
•
The USB interface is fully active.
Low power state
In this state (also called “airplane mode”), RF (both Rx and Tx) is disabled in the
module, but the USB interface is still active.
Usage models
Usage models can be used to calculate expected current consumption. A sample
usage model is provided in Table 2-1,
Table 2-1: Power consumption of sample application

This example model applies to a battery-operated device. In practice, because
the module is isolated from the battery (the host device manages the power
source), the mAh ratings depend on the module’s supply efficiency.
The module automatically enters slotted sleep mode when there is no
transmission or reception occurring (SCI = 2).
Transmit power is assumed to be +3 dBm.

RF connection
When attaching an antenna to the module:
Note: To disconnect the
antenna, make sure you
use the Hirose U.FL
connector removal tool
(P/N UFL-LP-N-2(01)) to
prevent damage to the
module or coaxial cable
assembly.
•
Use a Hirose U.FL connector (model U.FL #CL331-0471-0-10) to attach an
antenna to a connection point on the module.
•
Match coaxial connections between the module and the antenna to 50 
•
Minimize RF cable losses to the antenna; the recommended maximum cable
loss for antenna cabling is 0.5 dB.
Ground connection
When connecting the module to system ground:
•
Prevent noise leakage by establishing a very good ground connection to the
module through the host connector.
•
Connect to system ground using the two mounting holes at the top of the
module.
•
Minimize ground noise leakage into the RF.
Depending on the host board design, noise could potentially be coupled to
the module from the host board. This is mainly an issue for host designs that
have signals traveling along the length of the module, or circuitry operating at
both ends of the module interconnects.
Shielding
The module is fully shielded to protect against EMI and to ensure compliance with
FCC Part 15 - “Radio Frequency Devices” (or equivalent regulations in other
jurisdictions).
Note: The module shields must NOT be removed.
Note: Values in this guide
are taken from the appropriate product specification documents (PSDs)
(listed in Related
documents on page 9)—in
the case of a discrepancy
between this document
and the relevant PSD, use
the value listed in the PSD.
18
Antenna and cabling
When selecting the antenna and cable, it is critical to RF performance to match
antenna gain and cable loss.
Choosing the correct antenna and cabling
Consider the following points for proper matching of antennas and cabling:
•
The antenna (and associated circuitry) should have a nominal impedance of
50  with a return loss of better than 10 dB across each frequency band of
operation.
•
The system gain value affects both radiated power and regulatory (FCC, IC,
CE, etc.) test results.
Proprietary and Confidential
2130114
RF Integration
Developing custom antennas
Consider the following points when developing custom-designed antennas:
•
A skilled RF engineer should do the development to ensure that the RF
performance is maintained.
•
Identify the bands that need to be supported.
Determining the antenna’s location
Consider the following points when deciding where to put the antenna:
Note: These modules are
based on ZIF (Zero Intermediate Frequency)
technologies. When
performing EMC (Electromagnetic Compatibility)
tests, there are no IF
(Intermediate Frequency)
components from the
module to consider.
•
Antenna location may affect RF performance. Although the module is
shielded to prevent interference in most applications, the placement of the
antenna is still very important—if the host device is insufficiently shielded,
high levels of broadband or spurious noise can degrade the module’s performance.
•
Connecting cables between the module and the antenna must have 50 
impedance. If the impedance of the module is mismatched, RF performance
is reduced significantly.
•
Antenna cables should be routed, if possible, away from noise sources
(switching power supplies, LCD assemblies, etc.). If the cables are near the
noise sources, the noise may be coupled into the RF cable and into the
antenna.
Interference and sensitivity
Several sources of interference can affect the RF performance of the module
(RF desense). Common sources include power supply noise and devicegenerated RF.
RF desense can be addressed through a combination of mitigation techniques
and radiated sensitivity measurement.
Power supply noise
Noise in the power supply can lead to noise in the RF signal.
Note: Values in this guide
are taken from the appropriate product specification documents (PSDs)
(listed in Related
documents on page 9)—in
the case of a discrepancy
between this document
and the relevant PSD, use
the value listed in the PSD.
The power supply ripple limit for the module is no more than 200 mVp-p 1 Hz to
100 kHz. This limit includes voltage ripple due to transmitter burst activity.
Interference from other wireless devices
Wireless devices operating inside the host device can cause interference that
affects the module.
To determine the most suitable locations for antennas on your host device,
evaluate each wireless device’s radio system, considering the following:
•
Rev 2.02 Sep.10
Any harmonics, sub-harmonics, or cross-products of signals generated by
wireless devices that fall in the module’s Rx range may cause spurious
response, resulting in decreased Rx performance.
Proprietary and Confidential
19
AirPrime Embedded Module Hardware Integration Guide
•
The Tx power and corresponding broadband noise of other wireless devices
may overload or increase the noise floor of the module’s receiver, resulting in
Rx desense.
The severity of this interference depends on the closeness of the other antennas
to the module’s antenna. To determine suitable locations for each wireless
device’s antenna, thoroughly evaluate your host device’s design.
Device-generated RF
Note: The module can
cause interference with
other devices such as
hearing aids and on-board
speakers.
All electronic computing devices generate RF interference that can negatively
affect the receive sensitivity of the module.
Wireless devices such as
AirPrime embedded
modules transmit in bursts
(pulse transients) for set
durations (RF burst
frequencies). Hearing aids
and speakers convert
these burst frequencies
into audible frequencies,
resulting in audible noise.
•
Microprocessor and memory
•
Display panel and display drivers
•
Switching-mode power supplies
The proximity of host electronics to the antenna in wireless devices can contribute
to decreased Rx performance. Components that are most likely to cause this
include:
These and other high-speed devices (in particular, the processor) can decrease
Rx performance because they run at frequencies of tens of MHz. The rapid rise
and fall of these clock signals generates higher-order harmonics that often fall
within the operating frequency band of the module, affecting the module’s receive
sensitivity.
Example
On a sub-system running at 40 MHz, the 22nd harmonic falls at 880 MHz, which
is within the cellular receive frequency band.
Note: In practice, there are usually numerous interfering frequencies and harmonics. The
net effect can be a series of desensitized receive channels.
