Abstract: An oscillatory circuit. The oscillatory circuit includes a first oscillator, a second oscillator, and a mixer circuit. The first oscillator is configured to generate a first oscillating signal at a first frequency and has a first frequency temperature coefficient. The second oscillator is configured to generate a second oscillating signal at a second frequency and has a second frequency temperature coefficient. The second frequency is greater than the first frequency, and the second frequency temperature coefficient is less than the first frequency temperature coefficient. The mixer circuit is configured to receive the first oscillating signal from the first oscillator, to receive the second oscillating signal from the second oscillator, and to generate a mixer signal from the first and the second oscillating signals. The mixer signal comprises a signal component at a beat frequency. The beat frequency is equal to the difference between the second frequency and the first frequency.

Abstract: Systems and methods of detecting wireless channel status from acoustic discrimination of spectral content are described. In one aspect, a wireless system includes a spectrum analyzer, a detector, and a controller. The spectrum analyzer is operable to acoustically discriminate spectral content of an input electrical signal in multiple discrete frequency channels. The detector is operable to determine respective statuses of the frequency channels from the acoustically discriminated spectral content. The controller is operable to select one of the frequency channels based on the determined statuses of the frequency channels.

Abstract: An RF switching circuit that incorporates a film bulk acoustic resonator (FBAR) device and one or more capacitors that are used to vary the capacitance of the FBAR device to change the frequency range that is blocked by the FBAR device. When the RF switching circuit is in a first switching state, a first set of RF signals in a first frequency range is blocked by the RF switching circuit while RF signals of other frequencies are passed by the RF switching circuit. When the RF switching circuit is in a second switching state, a second set of RF signals in a second frequency range is blocked by the RF switching circuit while RF signals of other frequencies are passed by the RF switching circuit.

Abstract: A filter and method of manufacturing a filter having a lattice arrangement that efficiently utilizes substrate space. An embodiment of the invention is directed to a filter having a plurality of resonators disposed on a substrate, each resonator comprising a first electrode and a second electrode disposed vertically adjacent such that an acoustic cavity of a piezoelectric material is formed between each first electrode and each second electrode of each resonator, the first and second electrodes of each resonator electrically isolated from each other via the piezoelectric material. In this manner, the filter is realized without having to use any vias. Additionally, the resonators may be of a shape that allows each to be disposed close together such that some sides of each of the resonators are parallel to each other. Thus, substrate space can be preserved even further.

Abstract: An apparatus including vertically separated acoustic resonators are disclosed. The apparatus includes a first acoustic resonator on a substrate and a second acoustic resonator vertically separated above the first acoustic resonator. Because the resonators are vertically separated above another, total area required to implement the resonators is reduced thereby savings in die size and cost are realized. The vertically separated resonators are supported by standoffs that are fabricated on the substrate, or on a resonator.
