Product Technical Specification & Customer Design Guidelines Power supply The host provides power to the MC7330 through multiple power and ground pins as summarized in Table 3-2. 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. Table 3-2: Power and ground specifications Name Pins Specification Min VCC 2, 24, 39, 41, 52 Voltage range See Table 3-1 on page 26.
Electrical Specifications USB high/full speed throughput performance This device has been designed to achieve optimal performance and maximum throughput using USB high speed mode. Although the device may operate with a full speed host, throughput performance will be on an “as is” basis and needs to be characterized by the OEM. Note that throughput will be reduced and may vary significantly based on packet size, host interface, and firmware revision.

Product Technical Specification & Customer Design Guidelines Control interface (Signals) The MC7330 provides signals for: • Waking the host when specific events occur • Host control of the module’s radios • LED driver output These signals are summarized in Table 3-5 and paragraphs that follow. Table 3-5: Module control signals Name Pin Description Type 1 WAKE_N 1 Wake host OC W_DISABLE_N 20 Wireless disable (Main RF) PU WAN_LED_N 42 LED driver OC 1.
Electrical Specifications W_DISABLE_N — Wireless disable Note: Host support for wireless disable signals is optional. The host device uses W_DISABLE_N (pin 20) to enable/disable the WWAN or radio modem. When disabled, the modem cannot transmit or receive information. Letting this signal float high allows the module to operate normally. This switch follows the behavior described in [9] PCI Express Mini Card Electromechanical Specification Revision 1.2. This pin has a 20 k pull-up resistor.

4 4: RF Specifications The MC7330 includes three RF connectors for use with host-supplied antennas: • Main RF connector—Rx/Tx path • GNSS connector 1—Dedicated GNSS • Diversity/MIMO/GNSS connector 2—Diversity, MIMO, or GNSS The module does not have integrated antennas.
Product Technical Specification & Customer Design Guidelines Antenna and cabling When selecting the antenna and cable, it is critical to RF performance to optimize antenna gain and cable loss. Note: For detailed electrical performance criteria, see Appendix A: Antenna Specification on page 69.
RF Specifications Ground connection When connecting the module to system ground: • Prevent noise leakage by establishing a very good ground connection to the module through the host connector. • Connect to system ground using the two mounting holes at the top of the module (shown in Figure 4-1 on page 41). • Minimize ground noise leakage into the RF. Depending on the host board design, noise could potentially be coupled to the module from the host board.
Product Technical Specification & Customer Design Guidelines Proximity of host electronics to the antenna in wireless devices can contribute to decreased Rx performance. Components that are most likely to cause this include: • Microprocessor and memory • Display panel and display drivers • Switching-mode power supplies Device-generated RF interference The module can cause interference with other devices.

A A: Antenna Specification This appendix describes recommended electrical performance criteria for main path, diversity path, and GNSS antennas used with AirPrime embedded modules. The performance specifications described in this section are valid while antennas are mounted in the host device with antenna feed cables routed in their final application configuration. Note: Antennas should be designed before the industrial design is finished to make sure that the best antennas can be developed.

B B: Design Checklist This chapter provides a summary of the design considerations mentioned throughout this guide. This includes items relating to the power interface, RF integration, thermal considerations, cabling issues, and so on. Note: This is NOT an exhaustive list of design considerations. It is expected that you will employ good design practices and engineering principles in your integration.
Product Technical Specification & Customer Design Guidelines Table B-1: Hardware integration design considerations (Continued) Suggestion Section where discussed Keep very low capacitance traces on the USIM_DATA and USIM_CLK signals. SIM implementation on page 33 To minimize noise leakage, establish a very good ground connection between the module and host. Ground connection on page 43 Route cables away from noise sources (for example, power supplies, LCD assemblies, etc.).
C C: Testing Note: All AirPrime embedded modules are factory-tested to ensure they conform to published product specifications. Developers of OEM devices integrating Sierra Wireless AirPrime embedded modules should include a series of test phases in their manufacturing process to make sure that their devices work properly with the embedded modules.
Product Technical Specification & Customer Design Guidelines Acceptance test requirements To perform the suggested tests, you require a test system in which to temporarily install the module, and you must be able to observe the test device’s LED indicator. Acceptance test procedure The following is a suggested acceptance testing procedure using Sierra Wireless’ Skylight™ (formerly Watcher™) software: Note: You can perform these tests using appropriate AT commands.
Testing • GCF (Global Certification Forum—www.globalcertificationforum.org) outside of North America • PTCRB (PCS Type Certification Review Board—www.ptcrb.com) in North America Production testing Note: Production testing typically continues for the life of the product. Production testing ensures that, for each assembled device, the module is installed correctly (I/O signals are passed between the host and module), and the antenna is connected and performing to specifications (RF tests).

Test limits—Run ten or more good DUTs through this test procedure to obtain a nominal output power value. · Apply a tolerance of 5 to 6 dB to each measurement (assuming a good setup design). · Monitor these limits during mass-production ramp-up to determine if further adjustments are needed.
Testing To test the DUT’s receive path: Note: This procedure describes steps using the Agilent 8648C signal generator—the Rohde & Schwarz SML03 is shown for reference only. 1. Set up the signal generator: a. Set the amplitude to: · -80 dBm (WCDMA mode) · -60 dBm (GSM mode) b. Set the frequency for the band being tested. See Table C-2 on page 82 for frequency values. 2. Set up the DUT: a. AT!ENTERCND (Unlock extended AT command set.) b. AT!DAFTMACT (Put modem into factory test mode.) c.
Product Technical Specification & Customer Design Guidelines · Monitor these limits during mass-production ramp-up to determine if further adjustments are needed. Note: The value measured from the DUT is significantly influenced by the test setup and DUT design (host RF cabling loss, antenna efficiency and pattern, test antenna efficiency and pattern, and choice of shield box). 4. Test diversity paths: Note: Diversity is not available in GSM mode. a. Set up the signal generator as in Step 1.
Testing To test the DUT’s receive path (or diversity path, while connected to the diversity antenna): Note: This procedure describes steps using the Agilent 8648C signal generator—the Rohde & Schwarz SML03 is shown for reference only. 1. Set up the signal generator: a. Set the amplitude to -70 dBm b. Set the frequency for the band being tested. See Table C-3 on page 84 for frequency values. 2. Set up the DUT: a. AT!ENTERCND (Unlock extended AT command set.) b.
Product Technical Specification & Customer Design Guidelines GNSS RF receive path test The GNSS receive path uses either the dedicated GNSS connector or the shared Diversity/MIMO/GNSS connector. To test the GNSS receive path: 1. Inject a carrier signal at -110dBm, frequency 1575.52 MHz into the GNSS Rx path at the connector. (Note that this frequency is 100 kHz higher than the actual GPS L1 center frequency.) 2. Test the signal carrier-to-noise level at the GNSS receiver: a.
Testing • Channel and average power measurements to verify that the device is transmitting within product specifications • RF sensitivity testing—BER/BLER for different bands and modes • Transmitter and receiver tests (based on relevant sections of the 3GPP TS51010 and 3GPP 34121 documents) Suggested testing equipment To perform production and post-production tests, you will require appropriate testing equipment.
