` 1 Introduction The Iridium CertusTM 9770 is a transceiver designed to be used inside a Value-Added Manufacturer (VAM) product as per Figure 1-1 below. The Iridium Certus 9770 provides satellite messaging, IP data and voice connectivity using Iridium’s NEXT satellite constellation. Iridium’s satellite services using the Iridium Certus 9770 are provided by Iridium Certus Service Providers (SP) to end users.
` 1.
` EXT_PWR accepts input voltages of +12 VDC +/- 2.5 V with an input ripple less than 40 mV peakto-peak. The maximum operational input current for the Iridium Certus 9770 in stable operation is 1.5 A. Note: For safety compliance the external power source should meet requirements of IEC 623681 classes ES1 & PS2. 3 RF Interface The Iridium Certus 9770 has a dedicated RF connector that provides a connection to an external passive antenna. 3.
` control level. Conducted RF peak power may be up to 6 dB higher than the average RF power measured over a transmit burst. 3.4 Conductive RF Inputs The absolute maximum RF input into the Iridium Certus 9770 should not exceed +5 dBm; otherwise, damage to the Iridium Certus 9770 is possible. 3.5 RF Cable Considerations For safety reasons, the RF connector on the Iridium Certus 9770 should not be directly connected to an external antenna cable or cable distribution system.
` The Iridium Certus 9770 overall dimensions are 140.2 mm X 60.0 mm X 16.3 mm and its mass is 185 g. 4.2 Enclosure Material The enclosure material is an Aluminum Alloy ADC10 with a RoHs Compliant Chromate Conversion coating.

` 4.3 Mechanical Drawing Figure 4.3-1 below shows the mechanical dimensions of the Iridium Certus 9770. CAD files for the Iridium Certus 9770 are also available in STEP and Parasolid files as per References 2 and 3 respectively.

IR3142-ICD-006 Issue 1 v2.
` 4.4 Mounting Considerations The Iridium Certus 9770 has six mounting holes with clearance for M3 screws that can be used to secure the transceiver to a VAM product. The Iridium Certus 9770 should be assembled into a VAM product by pushing the transceiver straight down onto a VAM product’s mating connector, ensuring not to rotate or twist the transceiver. The mechanical drawings in section 4.3 define a keep-out region.
` ambient environment to ensure that both the Iridium Certus 9770’s ambient and case temperature does not exceed the temperatures in Table 4.6-1. If the Iridium Certus 9770 gets too hot, its thermal protection circuitry can shut the transceiver off and put it into a fault mode. Once the Iridium Certus 9770 enters a fault mode, a reset or power up is required to recover.
` 6 Regulatory Approvals The Iridium CertusTM 9770 Transceiver is a regulatory approved module that can be fitted within an enclosed host system. With appropriate external connections, the host system can be designed to meet full transceiver regulatory tests and sold as a Regulatory Certified product that meets CE, FCC and IC requirements. The Iridium CertusTM 9770 is tested to the regulatory and technical certifications shown in Table 2 (See Note below).
` 6.2 Radio Interference This device complies with Part 15 of the FCC Rules and Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device.
` determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help. 6.
