Abstract: A device includes a substrate that includes a resonant cavity. The resonant cavity includes a plurality of dipolar molecules that have an absorption frequency. The resonant cavity resonates at a frequency that is equal to the absorption frequency of the dipolar molecules. The device further includes a first port on the resonant cavity configured to receive a radio frequency (RF) signal.

Abstract: A pressure transducer includes a cavity, dipolar molecules disposed within the cavity, and pressure measurement circuitry. The pressure measurement circuitry is configured to measure a width of an absorption peak of the dipolar molecules, and to determine a value of pressure in the cavity based on the width of the absorption peak.

Abstract: An apparatus comprises a piezoelectric resonator, a first active inductor circuit, and a second active inductor circuit. The piezoelectric resonator includes a first resonator terminal and a second resonator terminal. The first active inductor circuit is coupled between the first resonator terminal and a power supply terminal, the first active inductor circuit having a first impedance that reduces with a first frequency where the first frequency is at or above 1 GHz. The second active inductor circuit is coupled between the second resonator terminal and the power supply terminal, the second active inductor circuit having a second impedance that reduces with a second frequency where the second frequency is at or above 1 GHz.

Abstract: A bidirectional phase shifter includes a differential quadrature hybrid coupler, a switch network, and a differential reflection type phase shifter (RTPS). The differential quadrature hybrid coupler includes a first phase input/output (I/O) port, an inverse first phase I/O port, a second phase I/O port, and an inverse second phase I/O port. The switch network is coupled to the first phase I/O port, the inverse first phase I/O port, the second phase I/O port, and the inverse second phase I/O port. The differential RTPS including a differential I/O port coupled to the switch network.

Abstract: An integrated circuit (IC) includes a semiconductor substrate having a first surface and a second surface opposite the first surface. A through wafer trench (TWT) extends from the first surface of the semiconductor substrate to the second surface of the semiconductor substrate. Dielectric material is in the TWT. An interconnect region has layers of dielectric on the first surface of the substrate. The interconnect region has a conductive transmit patch. An antenna is formed, at least in part, by the dielectric material in the TWT and the transmit patch in the interconnect region. The antenna is configured to transmit or receive electromagnetic radiation between the transmit patch and the second surface of the semiconductor substrate through the dielectric material within the trench.

Abstract: An integrated circuit (IC) includes a semiconductor substrate and an interconnect region. The semiconductor substrate has a first surface and a second surface opposite the first surface. The semiconductor substrate has a first region with a passive component. The semiconductor substrate has a second region outside the first region. The resistance of the second region is smaller than the resistance of the first region. The interconnection region is on the second surface of the semiconductor substrate.
