Abstract: In an example, a system includes a BAW resonator. The system also includes a first heater configured to heat the BAW resonator, where the first heater is controlled by a first control loop. The system includes a circuit coupled to the BAW resonator. The system also includes a second heater configured to heat the circuit, where the second heater is controlled by a second control loop.

Abstract: A system includes first and second gas cells each comprising a respective sealed interior waveguide; first transmit antenna coupled to the first gas cell to provide a first electromagnetic wave to the first gas cell along a first direction; second transmit antenna coupled to the first gas cell to provide a second electromagnetic wave to the first gas cell along a second direction opposite the first direction; third transmit antenna coupled to the second gas cell to provide a third electromagnetic wave to the second gas cell; first receive antenna coupled to the first gas cell to generate a first signal indicative of an amount of energy in first electromagnetic wave; second receive antenna coupled to the second gas cell to generate a second signal indicative of an amount of energy in second electromagnetic wave; and processor to calculate a background-free signal based on a difference between first and second signals.

Abstract: A clock generator includes a hermetically sealed cavity and clock generation circuitry. A dipolar molecule in the hermetically sealed cavity has a quantum rotational state transition at a fixed frequency. The clock generation circuitry generates an output clock signal based on the fixed frequency of the dipolar molecule. The clock generation circuitry includes a detection circuit, a reference oscillator, and control circuitry. The detection circuit generates a first detection signal and a second detection signal representative of amplitude of signal at an output of the hermetically sealed cavity responsive to a first sweep signal and a second sweep signal input to the hermetically sealed cavity. The control circuitry sets a frequency of the reference oscillator based on a difference in time of identification of the fixed frequency of the dipolar molecule in the first detection signal and the second detection signal.

Abstract: In a described example, an apparatus includes a first substrate having a first side, a second side, and a coupling interface across a portion of the first side. The coupling interface including an arrangement of subwavelength periodic structures formed in the first substrate. A second substrate is coupled to a portion of the second side of the first substrate to form a sealed cavity aligned with the coupling interface.

Abstract: A system includes first and second gas cells, each comprising a respective sealed interior waveguide. The first gas cell contains a dipolar gas and the second gas cell does not contain a dipolar gas. The system includes first and second transmit antennas coupled to the first and second gas cells, respectively, to provide first and second electromagnetic waves to the interior of the first and second gas cells, respectively; first receive antenna coupled to the first gas cell to generate a first signal indicative of an amount of energy in the first electromagnetic wave after travel through the first gas cell; second receive antenna coupled to the second gas cell to generate a second signal indicative of an amount of energy in the second electromagnetic wave after travel through the second gas cell; processor configured to calculate a background-free signal based on a difference between the first and second signals.
