Antenna Control
Note: Host support for antenna control signals is optional.
The EM7411 provides four output signals (listed in Table 2-10) that may be used for host
designs that incorporate tunable antennas. Customers can configure these signals as
appropriate for the operating band(s) using the command AT!ANTSEL.
Note:
•
Lantronix, Inc. recommends that two signals be used for high bands, and the other
two signals for low/mid bands.
•
To avoid detuning the PCC band, customers must make sure there are no GPIO state
conflicts between the PCC and SCC for all supported CA combinations.
