LTE cellular antenna S11

[Valentinas]

Can a high reflection coefficient (say -1dB instead of wanted <-6dB) damage the LTE transceiver or does it have internal protection?

Is it possible to disable the unwanted LTE bands in FW?

Is it possible to disable the unwanted LTE bands in FW?

Its possible to band lock so that only a select number of bands are used. https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/mob_termination_ctrl_status/xbandlock.html?cp=2_2_0_4_12

Not sure about this so will ask interlay and update.

What we have that we can share is that the transceiver is able to withstand VSWR 10:1 at antenna port without breaking.
