Page 9: Power
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. - Page 10 Hardware Integration Guide Specifications subject to change 4118723...

Page 13: Routing Constraints And Recommendations
4: Routing Constraints and Recommen- dations 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. -
Page 14: Antenna
• 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. -
Page 15: Uim Interface
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: ·... -
Page 16: 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. -
Page 17: Mechanical Integration
Attention should be paid to: • Antenna cable integration (bending, length, position, etc) • Pads of the AirPrime WP8548 to be soldered to the ground plane • Ensuring proper board layout • Providing sufficient space around the module for heat dissipation Rev 2 Feb.16... -
