Simulation of Nonlinear Resonance, Amplitude–Frequency, and Harmonic Generation Effects in SAW and BAW Devices

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2020
Nonlinearly coupled sets of piezoelectric field equations in the frequency domain were derived for the nonlinear propagation of finite-amplitude waves in piezoelectric bulk acoustic wave (BAW) and surface acoustic wave (SAW) devices.

Band Reject Filter in BAW Technology

2008 38th European Microwave Conference, 2008
This document shows the feasibility of a band reject filter in Bulk Acoustic Wave (BAW) technology. This type of filter is usually composed of series and shunt resonators. We present two setups centred at 2.5 GHz which measurement is agreed with simulation for rejection band.

BAW resonators reliability in the GHz range

IECON 2006 - 32nd Annual Conference on IEEE Industrial Electronics, 2006
Bulk Acoustic Wave (BAW) resonators are very promising candidates for Giga Hertz applications. In this context it becomes really important to analyse the behavior of these structures under harsh environmental conditions and severe operating conditions.

BAW Filters for 5G Bands

International Electron Devices Meeting, 2018
The number of frequency bands requiring BAW filters is expected to grow significantly with the launch of 5G mobile applications. BAW is in particular well suited to address the new radio bands below 6 GHz also referred to as nr-1.

Multiphysics Modeling of BAW Filters

2015 IEEE International Ultrasonics Symposium (IUS), 2015
A novel approach for multiphysics modeling of BAW filters is presented allowing accurate and at the same time efficient modeling of BAW filters at high power levels. The approach takes the different types of losses and their spatial distribution into account in order to provide the required input for thermal simulation.

3.1 An Integrated BAW Oscillator with <±30ppm Frequency Stability Over Temperature, Package Stress, and Aging Suitable for High-Volume Production

IEEE International Solid-State Circuits Conference, 2020
Wireless sensor nodes with low power and small form factor are desirable for emerging IoT applications. These nodes usually consist of a processor, memory, radio, sensors, battery, and two quartz crystals: one at 32kHz to synchronize data transmission ...

Piezoelectrically actuated micromechanical BAW resonators

2008 IEEE Ultrasonics Symposium, 2008
We report on piezoelectrically actuated 13 MHz silicon beam resonators operating in the fundamental length extensional BAW mode. The resonance is evoked using an aluminum nitride layer grown on top of the resonator. We demonstrate quality factors as high as Q~55000 in vacuum, and transduction factors of the order of eta~20 muN=V.

Dual-Mode Hybrid Quasi-SAW/BAW Resonators With High Effective Coupling Coefficient

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2020
This article reports on a design journey for ScxAl1 – N-based dual-mode hybrid quasi-surface and bulk acoustic wave (quasi-SAW/BAW) resonators. Four types of acoustic excitation configurations are proposed in these designs based on Scx Al1–xN/6H-SiC ...

Neue Wohlverhaltensrichtlinie des BAWe

Zeitschrift für Bankrecht und Bankwirtschaft, 2000
Abstract Die nationale Umsetzung der Wertpapierdienstleistungsrichtlinie, die durch die Sechste KWG-Novelle erfolgt ist, hat auch die Anpassung der Ausführungsbestimmungen und Auslegungshinweise der Aufsichtsämter zum Wertpapierdienstleistungsgeschäft erforderlich gemacht (vgl. dazu im einzelnen Klanten, ZBB 2000, 349, in diesem Heft).
