Preliminary Rev 0.5 June 21, 2010 2 Product Specification 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. Limitations of Liability This manual is provided “as is”.

Preliminary Rev 0.5 June 21, 2010 16 Product Specification RF Circuit Routing Constraints 7. RF Circuit Routing Constraints 7.1. General 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 2. 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.

Preliminary Rev 0.5 June 21, 2010 17 Product Specification RF Circuit Routing Constraints Poor routing Correct routing The yellow traces cross the RF trace. There is no signal around the RF path. Figure 3. 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. 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. Note the figure below shows several internal ground layers cutout, which may not be necessary for every application. Figure 4. Coplanar clearance example Figure 5. Antenna microstrip routing example

Preliminary Rev 0.5 June 21, 2010 18 8. Regulatory Information 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. Safety and Hazards Do not operate you AR3550/GMT-2 modem: 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 AR5550 modem MUST BE POWERED OFF. Otherwise, the AR5550 modem can transmit signals that could interfere with this equipment In an aircraft, the AR5550 modem MUST BE POWERED OFF. Otherwise, the AR3550/GMT-2 modem 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 AR5550 modem may be used normally at this time. Important Compliance Information for USA OEM Integrators The AR5550 modem is granted with a modular approval for mobile applications. Integrators may use the AR5550 modem in their final products without additional FCC/IC (Industry Canada) certification if they meet the following conditions. Otherwise, additional FCC/IC approvals must be obtained. 1. At least 20cm separation distance between the antenna and the user’s body must be maintained at all times. 2. To comply with FCC/IC regulations limiting both maximum RF output power and human exposure to RF radiation, the maximum antenna gain including cable loss in a mobile-only exposure condition must not exceed 4.25dBi for CDMA 800 band and 6.1dBi for CDMA PCS band. 3. The AR5550 modem and the antenna must not be co-located or operating in conjunction with any other transmitter or antenna within a host device. 4. A label must be affixed to the outside of the end product into which the AR5550 modem is incorporated, with a statement similar to the following: a. For AR3550: This device contains FCC ID: N7NAR3550

Preliminary Rev 0.5 June 21, 2010 19 Product Specification Regulatory Information This equipment contains equipment certified under IC: 2417C-AR3550 b. For GTM-2: This device contains FCC ID: N7NGTM2 This equipment contains equipment certified under IC: 2417C-GTM2 A user manual with the end product must clearly indicate the operating requirements and conditions that must be observed to ensure compliance with current FCC/IC RF exposure guidelines. The end product with an embedded AR5550 modem may also need to pass the FCC Part 15 unintentional emission testing requirements and be properly authorized. Note: If this module is intended for use in a portable device, you are responsible for separate approval to satisfy the SAR requirements of FCC Part 2.1093 and IC RSS-102.
