摘要： 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.

摘要： 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.

摘要： 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.
