1 1: Introduction Sierra Wireless’ AirPrime Intelligent Embedded Modules form the radio component for the products in which they are embedded. The AirPrime MC7700 is available for use on LTE, WCDMA and GSM networks. Note: An understanding of network technology, and experience in integrating hardware components into electronic equipment is assumed.

2 2: Power Interface Overview of operation AirPrime embedded modules are designed to use a 3.3V (nominal) power supply 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 W_Disable#.
AirPrime MC7700 Hardware Integration Guide Module power states The module has five power states, as described in Table 2-1.
3 3: RF Integration The AirPrime MC7700 operates on the frequency bands listed below.
AirPrime MC7700 Hardware Integration Guide 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.
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: • Antenna location may affect RF performance.
AirPrime MC7700 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.

AirPrime MC7700 Hardware Integration Guide Important compliance information for North American users The MC7700 modem has been granted modular approval for mobile applications. Integrators may use the MC7700 modem in their final products without additional FCC/IC (Industry Canada) certification if the following conditions are met. Otherwise, additional FCC/IC approvals must be obtained. 1. At least 20 cm separation distance between the MC7700 antenna and the user’s body must be maintained at all times. 2.
4. A label must be affixed to the outside of the end product into which the MC7700 modem is incorporated, with a statement similar to the following: This device contains FCC ID: N7NMC7700. Contains transmitter module IC: 2417C-MC7700 where 2417C-MC7700 is the module’s certification number. 5. 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.
