1. A transducer for noninvasively measuring temperature within a body of a subject, comprising:

  • a circuit board including a front side and a back side opposite from the front side, the circuit board defining an antenna for receiving at least one native temperature signal from a location of interest within a body of a subject;

    wherein the circuit board carries at least a portion of an electrical circuit including the antenna, a capacitor and the thermistor, the capacitor being positioned in series between a receiving aperture and the thermistor, the thermistor being in direct communication with the cable connector;

    a reference temperature sensor; and

    a coaxial cable connector for transmitting a multiplexed signal including an intermediate temperature signal from the antenna and a reference temperature signal from the reference temperature sensor, wherein the coaxial cable connector and an end of a cable are configured to swivel relative to one another upon connecting the end of the cable to the cable connector.
