Abstract
A non-invasive analyte sensor includes a receive side with a superheterodyne circuit. The superheterodyne circuit include a mixer with an input that is electrically connected to a receive antenna, and a radio frequency generator connected to another input of the mixer and that is configured to generate a radio frequency signal. The mixer outputs a signal that is based on a frequency of a signal received by the receive antenna and the frequency of the signal generated by the radio frequency generator.
