2.9 Antenna dynamic tuner interface

☞ The antenna dynamic tuner interface is not supported by LARA-R6001-00B, LARA-R6001D-00B

and LARA-R6801-00B modules product versions.

The LARA-R6401 and LARA-R6401D modules includes two 1.8 V digital output pins (RFCTRL1 and

RFCTRL2) that are configured to control in real time an external antenna tuning IC, as optional

available feature, changing their output value dynamically according to the specific actual cellular

band in use by the module as indicated in Table 6.
