摘要： A bulk acoustic wave resonator structure that isolates the core resonator from both environmental effects and aging effects. The structure has a piezoelectric layer at least partially disposed between two electrodes. The structure is protected against contamination, package leaks, and changes to the piezoelectric material due to external effects while still providing inertial resistance. The structure has one or more protective elements that limit aging effects to at or below a specified threshold. The resonator behavior is stabilized across the entire bandwidth of the resonance, not just at the series resonance. Examples of protective elements include a collar of material around the core resonator so that perimeter and edge-related environmental and aging phenomena are kept away from the core resonator, a Bragg reflector formed above or below the piezoelectric layer and a cap formed over the piezoelectric layer.

摘要： A switchable power combiner is disclosed. The switchable power combiner has an output section that is a signal source connected to a transformer section. The transformer section has one or more primaries and a common secondary. The transformer primaries and secondary are acoustically coupled. The primaries or/and the secondary are made of switchable piezoelectric material, such that the acoustic coupling between any primary and the secondary can be switched on or off by electrical control, thereby implementing a switchable power combiner. The transformer secondary is connected to an antenna port. The power amplifier output section is segmented and connected to the transformer primaries. The power amplifier output section has a plurality of power amplifiers and a plurality of reactance elements, either fixed or variable. The switchable power combiner generates different linear load lines by switching on and off the coupling between any primary and the secondary.

摘要： A direct digital frequency synthesizer having a multi-modulus divider, a numerically controlled oscillator and a programmable delay generator. The multi-modulus divider receives an input clock having an input pulse frequency fosc and outputs some integer fraction of those pulses at an instantaneous frequency fVp that is some integer fraction (1/P) of the input frequency. The multi-modulus divider selects between at least two ratios of P (1/P or 1/P+1) in response to a signal from the numerically controlled oscillator. The numerically controlled oscillator receives an accumulator increment (i.e., the number of divided pulse edges) required before an overflow occurs that causes the multi-modulus divider to change divider ratios in response to an overflow. The numerically controlled oscillator also outputs both the overflow signal and a delay signal to the delay generator. The delay signal contains phase-dithering noise that is induced by input from a pseudo-random noise generator.

摘要： A tunable acoustic resonator device. The device has a piezoelectric medium as a first thin film layer and a tunable crystal medium as a second thin film layer. The tunable crystal medium has a first acoustic behavior over an operating temperature range under a condition of relatively low applied stress and a second acoustic behavior under a condition of relatively high applied stress. The acoustic behaviors are substantially different. The tunable crystal medium has a highly field-polarizable and lattice-deformable, substantially centrosymmetric structure over an operating temperature range under a condition of relatively low applied stress. The tunable crystal medium has a substantially non-centrosymmetric structure over said operating temperature range under a condition of relatively high applied stress. The dielectric permittivity of the tunable crystal medium is at least 100 at the relatively low applied stress. The tunable crystal medium is close to its ferroelectric instability but remains paraelectric throughout the operating temperature range of the device. The phase transition temperature of the tunable crystal medium from paraelectric to ferroelectric state is just below the operating temperature range.

摘要： A tunable acoustic resonator device has a piezoelectric medium as a first thin film layer and a tunable crystal medium as a second thin film layer. The tunable crystal medium has a first acoustic behavior over an operating temperature range under a condition of relatively low applied stress and a second acoustic behavior under a condition of relatively high applied stress. The acoustic behaviors are substantially different and, consequently, the different levels of applied stress are used to tune the acoustic resonator device. Compared with the tunable resonator device consisting of only tunable crystal medium, a device having both the piezoelectric and tunable crystal medium has advantages such as larger inherent bandwidth and less nonlinearity with AC signals. The device also requires a smaller applied stress (i.e. bias voltage) to achieve the required frequency tuning.
