Radio Characteristics

6.3
The tables within this section contain radio characteristics of the 9601 SBD Transceiver.
Average Power during a transmit slot (max)
9601 SBD Transceiver antennas (Note 1)
Note that the total implementation loss for an antenna, connectors, cable, lightening arrestor and
any other RF component between the transceiver and the antenna shall not exceed 3dB.
Implementation loss higher than this will affect link performance and quality of service.
Note 1: This Transceiver has a different antenna connector to other Iridium transceivers
Note 2: Cable losses should be minimized.
Note 3: Link Margin given for free space.

7.0 Instructions for the safe Installation and use of the 9601

The 9601 is intended for integration into a finished product. The integrator of the 9601 is required to
connect a power supply, antenna, and user interface to the 9601. To ensure that the 9601 is correctly
installed the following general instructions (sub-section 5.1) are provided for the installer.
The integrator will be required to supply the end user of the integrated product, incorporating the 9601 with
operating instructions and any other information relating to the maintenance and safety of the equipment
(sub-section 5.2).

Instructions for the Integrator

•
The 9601 must be installed by an appropriately qualified installer and mounted securely as
described in section 3.4 of this document.
•
The power supply used to power the 9601 must be checked to ensure it meets the requirements
of sub-section 4.1.2 of this document.
•
Electrical connections to the 9601 multi-interface connector shall be as designated in Table 3 of
sub-section 3.3.1 of this document.
•
The current and voltage rating of the multi-interface connector cable shall meet the requirements of
the DC power input.
•
The electrical characteristics of the multi-interface connector cable shall not degrade the 9601
digital communications and analog audio signals.
•
The multi-interface connector cable will provide adequate screening from external electromagnetic
