Abstract
An aspect of the disclosure relates to a user equipment (UE) including: at least one antenna; a transceiver coupled to the at least one antenna, wherein the transceiver comprises: a resonator oscillator configured to generate a resonator signal; and a temperature sensor configured to generate a temperature signal related to a temperature of the resonator oscillator; an applications processor coupled to the transceiver; and a resonator field calibrator coupled to the applications processor and the transceiver.
