Total radiated efficiency of Ant1 or Ant2 > 50% on all bands Maximum antenna gain Must not exceed antenna gains due to RF exposure and ERP/ EIRP limits, as listed in the module’s FCC grant. 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. If antennas can be moved, test all Isolation between Ant1 and Ant2 (S21) > 10 dB 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. Maximum Voltage applied to antenna 36 Volts Measure power endurance over 4 Power handling > 2 W RF power on low bands > 1 W on high bands 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. 41110461 Rev 0.1 January 16, 2017 15 Hardware Integration Guide 1.4.

Routing Constraints and Recommendations Layout and routing of the AirPrime AR759x 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 AR759x 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: 41110461 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. 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. Note: 41110461 Coplanar Clearance Example The figure above shows several internal ground layers cut out, which may not be necessary for every application.

SuperSpeed USB adds two differential pairs (SSRX+ / SSRX- and SSTX+ / SSTX-). These pairs should be routed with the following considerations/constraints: 3.3. 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. Power and Ground Recommendations Power and ground routing is critical to achieving optimal performance of the AirPrime AR759x Series when integrated into an application. Recommendations: Do not use a separate GND for the Antennas. Connections to GND from the AirPrime AR759x 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. 41110461 Rev 0.1 January 16, 2017 24 Hardware Integration Guide 3.4. Routing Constraints and Recommendations 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 AR759x Series using the appropriate voltage levels. The figure below is a reference circuit for a digital input / output signal to / from the AirPrime AR759x Series. ApplVcc (1.2V – 3.6V) VCC_1V8 VCCB ApplGPIOx Figure 5. VCCA DIR Direction L = B to A H = A to B GPIOx AirPrime AR759x 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. 41110461 Rev 0.1 January 16, 2017 25 4.

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 AR7592: 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 AR7592 device MUST BE POWERED OFF. Otherwise, the AirPrime AR7592 device can transmit signals that could interfere with this equipment In an aircraft, the AirPrime AR7592 device MUST BE POWERED OFF. Otherwise, the AirPrime AR7592 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 AR7592 device may be used normally at this time. 5.3.
