1 1: Introduction Sierra Wireless’ Mini Card modules form the radio component for the products in which they are embedded. Mini Cards are available for use on CDMA and GSM networks, including: Note: Throughout this document, MC57xx and MC87xx refer to the entire suites of CDMA and GSM Mini Cards respectively. • MC5725 / MC5725V / MC5727 / MC5727V—Operate on CDMA networks using the CDMA IS‐95A, 1X, and 1xEV‐DO (IS‐ 856) network standards, and support GPS.
CDMA and GSM / UMTS Mini Card Hardware Integration Guide Required connectors Note: Contact vendors before choosing your connectors — the numbers included here are for reference only. Choose connectors that are appropriate to your design. When integrating these modules into your host device, you need the following connector types: • RF cables that mate with Hirose U.FL connectors (model U.FL #CL331‐0471‐0‐10).

2 2: Power Interface Overview of operation Note: This chapter contains information for CDMA (MC57xx) and GSM (MC87xx) modules. Information that is unique to specific module types is clearly identified. The module is 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.
CDMA and GSM / UMTS Mini Card Hardware Integration Guide Note: ESD protection is highly recommended for the USIM connector at the point where the contacts are exposed, and for any other signals from the host interface that would be subjected to ESD by the user of the product. Module power states The module has four power states: • Disconnected No power to the module. • Off Power to the module, but the module is powered off. • Normal The module is active.
Power Interface Normal state This is the active state of the module. In this state: • The module is fully powered. • The module is capable of placing / receiving calls or estab‐ lishing data connections on the wireless network. • The USB interface is fully active. Note: This is the default state when VCC3.3 is first applied in the absence of W_Disable# control. Low power mode In this state, RF (both Rx and Tx) is disabled in the module, but the USB interface is still active.
CDMA and GSM / UMTS Mini Card Hardware Integration Guide The module automatically enters slotted sleep mode when there is no transmission or reception occurring (SCI = 2).. Transmit power is assumed to be +3 dBm. 14 Proprietary and Confidential 2130114 In the event of a discrepancy in values between this guide and the Product Specification Document (PSD), the PSD takes precedence.
3 3: RF Integration The MC87xx operates on the frequencies detailed in Table 3‐1.
CDMA and GSM / UMTS Mini Card Hardware Integration Guide • Minimize RF cable losses to the antenna; the recommended maximum cable loss for antenna cabling is 0.5 dB. Figure 3-1: Antenna connection points and mounting holes 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 (as shown in Figure 3‐1).
RF Integration Note: The module shields must NOT be removed. Antenna and cabling Note: Values in this guide are taken from the appropriate product specification documents (PSDs) (listed in Related documents, page 8) — in the case of a discrepancy between this document and the relevant PSD, use the value listed in the PSD. When selecting the antenna and cable, it is critical to RF perfor‐ mance to match antenna gain and cable loss.
CDMA and GSM / UMTS Mini Card Hardware Integration Guide Disabling the diversity antenna • MC57xx — If your host device is not designed to use the MC57xx module’s diversity antenna, terminate the interface with a 50 Ω load. • MC8780 / MC8781 / MC8785V / MC8790 —Use the AT command !RXDEN=0 to disable receive diversity or !RXDEN=1 to enable receive diversity.
RF Integration Device-generated RF Note: The module can cause interference with other devices such as hearing aids and onboard speakers. Wireless devices such as the Mini Card transmit in bursts (pulse transients) for set durations (RF burst frequencies). Hearing aids and speakers convert these burst frequencies into audible frequencies, resulting in audible noise. All electronic computing devices generate RF interference that can negatively affect the receive sensitivity of the module.
