1 1: Introduction The AirPrime WP7601 is an industrial-grade LGA 239-pad module that provides voice and data connectivity on LTE networks. The module also provides GNSS functionality as a SKU-configuration. Accessories A hardware development kit is available for AirPrime WP-series modules. The kit contains hardware components for evaluating and developing with the module, including: • Development board • Cables • Antennas (Additional antennas may be required to support all bands.
2 2: Power Power Supply The host provides power to the AirPrime WP7601 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 WP76XX Product Technical Specification. Module Power States The module has three main power states, as described in Table 2-1.
3 3: RF Specifications The AirPrime WP7601 operates on the frequency bands listed below. Table 3-1: LTE Frequency Band Support Band Frequency (Tx) (MHz) Frequency (Rx) (MHz) B4 1710–1755 2110–2155 B13 777–787 746–756 Table 3-2: GNSS Frequency Band Support Band Frequencies (MHz) GPS 1575.42 ± 1.023 GLONASS 1597.52–1605.92 Galileo 1575.42 ± 2.046 BeiDou 1561.098 ± 2.
4: Routing Constraints and Recommendations This section describes general routing constraints and recommendations for the AirPrime WP7601 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.
Routing Constraints and Recommendations 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 10. PCB Specifications for the Application Board Sensitive signals (such as audio, UIM, and clocks) should be protected by ground planes/fills.
Hardware Integration Guide 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.
Routing Constraints and Recommendations 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 WP7601 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.

Hardware Integration Guide 1. The end product must use the RF trace design approved with the AirPrime WP7601 module. The Gerber file of the trace design can be obtained from Sierra Wireless upon request. 2. At least 20 cm separation distance between the antenna and the user’s body must be maintained at all times. 3.
Regulatory Compliance and Industry Certifications 6. 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 AirPrime WP7601 module may also need to pass the FCC Part 15 unintentional emission testing requirements and be properly authorized per FCC Part 15.
