2.8.3 Carrier Approval
The CM52 has undergone carrier qualification and has been approved referencing the antenna
connector. Any application intending to use the CM52 will likely be required to undergo similar
testing with the CM52 integrated into the application. For this reason it is strongly recommended
that the application is designed to accommodate exposing the antenna connector(s) of the CM52.
This will help insure that the qualification of the application with the carrier will be successful.
2.8.4 Antenna Diagnostics
The antenna diagnostics function consists of one antenna detection circuit per RF connector. Each
detection circuit can support antenna resistance (RL) values of 1 KΩ to 20 KΩ and 49.9 KΩ.
Internal resistance (R) value is either 10 KΩ or 49.9 KΩ, as required by the customer’s application.
AT commands are provided to query the status, query the limits and set the limits for the status:
GOOD, OPEN, or SHORTED. These commands are detailed in the CM52 Software User’s Guide and
AT Command.
The drawing below is a high level description of the antenna diagnostics circuit.
