https://devzone.nordicsemi.com/f/nordic-q-a/69065/qm12038-discontinuedHello We are developing a unit, based on nRF9160. In that design LTE switch QM12038 is used. The manufacturer Qovro has stopped production, so now we are looking for a replacement. We like to support different frequencies, but do not need GPSen-USTelligent Community 13Fri, 04 Dec 2020 13:36:43 GMThttps://devzone.nordicsemi.com/thread/283329?ContentTypeID=1Fri, 04 Dec 2020 13:36:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:db23af6c-e263-4b74-a562-3c6e640fe83bketiljo<p><span>1. You can use any RF switch as long as it can handle the power and frequency. Both parts you refer to can be used.&nbsp;</span></p> <p><span>2. Yes, the modem will set the switch to the correct position for the wanted frequency range.&nbsp;</span></p> <p><span></span>3.&nbsp;The&nbsp;<span>QM12038 has a non-intuitive logic so if you replace it with something else, make sure you adjust the MAGPIO AT command to match the new switch.&nbsp;<a href="https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/sip_pin_configuration/xmagpio.html?cp=2_1_5_1">https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/sip_pin_configuration/xmagpio.html</a>&nbsp;Other than this, there&#39;s no other changes needed to the FW.&nbsp;</span></p> <p><span></span><span><a href="https://infocenter.nordicsemi.com/topic/ug_thingy91/UG/thingy91/hw_description/hw_antenna_tuning.html">https://infocenter.nordicsemi.com/topic/ug_thingy91/UG/thingy91/hw_description/hw_antenna_tuning.html</a></span></p> <p><span>Remember that the MAGPIO pins are 1.8 V logic.
