摘要： A piezoelectric micromechanical ultrasonic transducer (PMUT) includes a diaphragm disposed over a cavity, the diaphragm including a piezoelectric layer stack including a piezoelectric layer, a first electrode electrically coupled with transceiver circuitry, and a second electrode electrically coupled with the transceiver circuitry. The first electrode may be disposed in a first portion of the diaphragm, and the second electrode may be disposed in a second, separate, portion of the diaphragm. Each of the first and the second electrode is disposed on or proximate to a first surface of the piezoelectric layer, the first surface being opposite from the cavity. The PMUT is configured to transmit first ultrasonic signals by way of the first electrode during a first time period and to receive second ultrasonic signals by way of the second electrode during a second time period, the first time period and the second time period being at least partially overlapping.

摘要： In conventional packaging strategies for mm wave applications, the size of the package is dictated by the antenna size, which is often much larger than the RFIC (radio frequency integrated circuit). Also, the operations are often limited to a single frequency which limits their utility. In addition, multiple addition build-up layers are required to provide the necessary separation between the antennas and ground layers. To address these issues, it is proposed to provide a device that includes an antenna package, an RFIC package, and an interconnect assembly between the antenna and the RFIC packages. The interconnect assembly may comprise a plurality of interconnects with high aspect ratios and configured to connect one or more antennas of the antenna package with an RFIC of the RFIC package. An air gap may be formed in between the antenna package and the RFIC package for performance improvement.

摘要： An inductor can include a first substrate, a magnetic piece, and a conductor. The first substrate can be formed within a second substrate. The magnetic piece can be connected to a first side of the first substrate. The conductor can be formed within the second substrate, on the second substrate, or both. The conductor can have an input and an output. The conductor can be configured to surround the first substrate without being in contact with the first substrate and without being in contact with the magnetic piece.

摘要： An apparatus may include one or more segmented piezoelectric micromechanical ultrasonic transducer (PMUT) elements. Each segmented PMUT element may include a substrate, an anchor structure disposed on the substrate and a membrane disposed proximate the anchor structure. The membrane may include a piezoelectric layer stack and a mechanical layer. The anchor structure may include boundary portions that divide the segmented PMUT element into segments. Each segment may have a corresponding segment cavity. The boundary portions may correspond to nodal lines of the entire membrane. The membrane may include a membrane segment disposed proximate each segment cavity. The membrane may be configured to undergo one or both of flexural motion and vibration when the segmented PMUT element receives or transmits signals.
