Abstract: Attenuators having phase shift and gain compensation circuits. In some embodiments, a radio-frequency (RF) attenuator circuit can include one or more attenuation blocks arranged in series between an input node and an output node, with each attenuation block including a local bypass path. The RF attenuator circuit can further include a global bypass path implemented between the input node and the output node. The RF attenuator circuit can further include a phase compensation circuit configured to compensate for an off-capacitance effect associated with at least one of the global bypass path and the one or more local bypass paths.

Abstract: Devices and methods for layout-dependent voltage handling improvement in switch stacks. In some embodiments, a switching device can include a first terminal and a second terminal, a radio-frequency signal path implemented between the first terminal and the second terminal, and a plurality of switching elements connected in series to form a stack between the second terminal and ground. The stack can have an orientation relative to the radio-frequency signal path, and the switching elements can have a non-uniform distribution of a first parameter based in part on the orientation of the stack.

Abstract: A surface acoustic wave resonator that has at least a first resonant frequency and a second resonant frequency is disclosed. The surface acoustic wave resonator can include an interdigital transducer electrode that is positioned over a piezoelectric layer. The interdigital transducer electrode includes fingers having a first pitch. The surface acoustic wave resonator can also include a first set of reflectors that is positioned over the piezoelectric layer. The first set of reflectors includes a first number of reflectors having a second pitch. The first pitch is greater than the second pitch. The surface acoustic wave resonator can also include a second set of reflectors that is positioned over the piezoelectric layer. The second set of reflectors includes a second number of reflectors having a third pitch. The second number of reflectors is different from the first number of reflectors.

Abstract: A method of making an acoustic sensor (e.g., a piezoelectric sensor for a piezoelectric microelectromechanical systems microphone) includes forming or depositing one or more piezoelectric layers to define a beam extending between a proximal portion and a distal tip (e.g., unsupported free end), the beam having a width in plan view that is greater at a location distal of the proximal portion than at the proximal portion. The method also comprises attaching the beam to a substrate in cantilever form so that the proximal portion of the beam is anchored to the substrate and the distal tip is a free unsupported end of the beam. One or more electrodes are disposed on or in the proximal portion of the beam.

Abstract: A line card receives a SYNC input signal and a first system clock signal. The line card generates a second system clock signal in a PLL and generates a SYNC output signal by dividing the second system clock signal in a divider circuit. The SYNC output signal is fed back as a SYNC feedback signal. The line card determines determining a closest edge of the first system clock signal to a transition of the SYNC input signal and determines a time difference between the closest edge of the first system clock signal and a transition of the SYNC feedback. The SYNC output signal is adjusted based on the time difference using a coarse adjustment by adjusting a divide ratio of the divider circuit and using a fine adjustment in the PLL based on a residue of a remainder of the time difference not accounted for by the coarse time adjustment.
