1. Introduction The Sierra Wireless AirPrime MC7304 PCI Express Mini Card is a compact, lightweight, wireless LTEand UMTS-based modem. It provides LTE, DC-HSPA+, HSPA+, HSDPA, HSUPA, WCDMA, GSM, GPRS, EDGE and GNSS connectivity for networking, and M2M applications over several radio frequency bands. The device also supports 2G/3G roaming, subject to carrier provisioning. 1.1.
2. Power Interface 2.1. Power Supply The host device must provide power to the MC7304 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 MC7304 mini card has four power states as detailed in the following table. Details RF Enabled USB Interface Active State Module is Powered Supported MC7304 Power States Host is Powered Table 3.

Hardware Integration Guide 3.4. RF Integration Antenna Guidelines 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. The system gain value affects both radiated power and regulatory (FCC, IC, CE, etc.) test results. 3.4.2.
4. Audio Interface The MC7304 supports a PCM/I2S 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 can be switched from PCM to I2S and vice versa via AT commands. Table 5.

Hardware Integration Guide Regulatory Information 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 MC7304 modem may be used normally at this time. 5.3.
