1. Introduction The Sierra Wireless MC7350-L PCI Express Mini Card is a compact, lightweight, wireless LTE-based modem. It provides LTE connectivity for networking. 1.1. Hardware Development Components Sierra Wireless manufactures the MC Series Development Kit, a hardware development component that is used to facilitate the hardware integration process. This development kit is the hardware development board on which an MC mini card is plugged.
2. Power Interface 2.1. Power Supply The host device must provide power to the MC7350-L mini card over pins 2, 24, 39, 41 and 52 (VCC) as detailed in the following table. Table 1. Power Supply Requirements Signal Name Pin VCC 2, 24, 39, 41, 52 GND 4, 9, 15, 18, 21, 26, 27, 29, 34, 35, 37, 40, 43, 50 Specification Minimum Typical Maximum Unit Voltage range 3.0 3.3 3.
Hardware Integration Guide 2.3. Power Interface Power States The MC7350-L mini card has four power states as detailed in the following table.
3. RF Integration 3.1. Supported RF Bands Table 4. Supported RF Bands Band/Connectivity Data Rates LTE Band 4 (AWS 1700/2100 MHz) HSPA+ rates LTE Band 13 (700 MHz) Downlink: Up to 42 Mbps (category 24) Uplink: Up to 5.76 Mbps (category 7) MIMO support Circuit-switched data bearers up to 64 kbps GPS 1575.42 MHz GLONASS 1602 MHz 3.2.
Hardware Integration Guide 3.4. RF Integration Antenna Guidelines When selecting the antenna and cable, it is critical to RF performance to match antenna gain and cable loss. 3.4.1. Choosing the Correct Antenna and Cabling Consider the following points for appropriate antenna selection: The antenna (and associated circuitry) should have a nominal impedance of 50Ω with a return loss of better than 10 dB across each frequency band of operation.
Hardware Integration Guide 3.5. RF Integration RF Desense Sources Common sources of interference that may affect the module’s RF performance (RF desense) include: Power supply noise Can lead to noise in the RF signal Module power supply ripple limit <= 100 mVp-p 1 Hz–100 kHz Interference from other embedded wireless devices Any harmonics, sub-harmonics, or cross-products of signals that fall in the module’s Rx range may cause spurious response, resulting in decreased Rx performance.
4. Audio Interface 2 The MC7350-L supports a PCM/I S digital audio interface using a dedicated serial link for digital audio data; all other signals, such as subcoding and control, are transmitted separately. The audio interface 2 can be switched from PCM to I S and vice versa via AT commands. Table 5.

Hardware Integration Guide Regulatory Information 5.3. Important Compliance Information for North American Users Note: Details are preliminary and subject to change. The MC7350-L modem has been granted modular approval for mobile applications. Integrators may use the MC7350-L 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.
Hardware Integration Guide Regulatory Information The end product with an embedded MC7350-L modem may also need to pass the FCC Part 15 unintentional emission testing requirements and be properly authorized per FCC Part 15. Note: 4115034 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. Rev 1.
