Abstract: An apparatus, system, and method for multi-frequency oscillator control are provided. A circuit can include a resonator circuit including an input and an output, the resonator circuit configured to resonate at a fundamental frequency and a different, non-fundamental frequency, a startup circuit electrically coupled to the input, the startup circuit configured to generate a signal at about the non-fundamental frequency and detect when the resonator circuit is resonating at the non-fundamental frequency, and an oscillator driver circuit electrically coupled to the output, the oscillator driver circuit configured to amplify and buffer the output of resonator circuit and drive a load.

Abstract: Techniques and mechanisms for regulating a temperature of a resonator structure. In an embodiment, a thermoelectric cooler (TEC) is thermally coupled to a resonator which is proximate thereto. The resonator supports operation with an oscillator circuit, wherein a resonance characteristic of the resonator contributes to oscillations of a master clock signal, or other oscillatory signal, which is provided with the oscillator circuit. The TEC provides Peltier functionality to selectively perform either one of heating or cooling the resonator. In another embodiment, the TEC is configured to conduct heat which is transferred via a path between the TEC and the resonator, wherein the path omits any circuitry which is to perform operations which are synchronized based on the oscillatory signal.

Abstract: An electric circuit includes a compensation circuit. The compensation circuit includes at least one directional coupler with an adjustable coupling factor. The compensation circuit is coupled between a first signal path and a second signal path of the electric circuit via the at least one directional coupler. Furthermore, the electric circuit includes a detector circuit coupled at least to the second signal path. The detector circuit is configured to detect an interfering signal portion of a signal of the first signal path in the second signal path. Furthermore, the electric circuit includes a control circuit. The control circuit is configured to adjust a transfer characteristic of the compensation circuit based on the detected interfering signal portion. Adjusting the transfer characteristic includes adjusting the coupling factor of the at least one directional coupler.

Abstract: Photonically steered impedance surface antennas are disclosed. A disclosed example apparatus includes a semiconductor substrate to be communicatively coupled to a radio frequency (RF) source, an at least partially transparent dielectric layer, the semiconductor substrate at a first side of the at least partially transparent dielectric layer, an at least partially transparent conductive film at a second side of the at least partially transparent dielectric layer that is opposite the first side of the at least partially transparent dielectric layer, and an illumination source to illuminate at least a portion of the semiconductor substrate to generate a photoinduced solid-state plasma pattern that beam steers an RF signal corresponding to the RF source.

Abstract: A circulator system for use in a simultaneous transmit and receive system includes a transmitter port connected to a first port of a circulator component by a phase shifter and possibly a pre-conditioning impedance, an antenna port connected to a second port of the circulator component by a pre-conditioning impedance, and a receiver port connected to a third port of the circulator component by a phase shifter and a pre-conditioning impedance. A loop with an impedance is connected between the transmitter port and the receiver port. A double loop circulator system includes further phase shifters and impedances at the first and third ports of the circulator component and a second loop with an impedance connected signal paths for the transmitter and receiver ports, being connected between the phase shifters in the signal paths. High isolation between the transmitter and receiver ports is provided.
