Fast modeling of lateral modes in BAW resonators with arbitrary in-plane geometry
IUS, 2022The Transmission Line Matrix (TLM) method is used to model and predict lateral spurious resonances in a BAW resonator. The dispersive characteristics of the main propagating mode, which are defined by the stack of materials, are considered with ...

Optimization Method for Single-Mode Performance of Laterally Excited BAW Resonators (XBARs)
IUS, 2022This paper describes a method of optimization of Laterally Excited Bulk Acoustic Resonators (so-called XBARs) for single-mode performance and suppression of spurious modes. The method is based on analysis of the bulk acoustic wave (BAW) slowness surface.

Wideband 6 GHz RF Filters for Wi-Fi 6E Using a Unique BAW Process and Highly Sc-doped AlN Thin Film
Intelligent Memory Systems, 2021A Wi-Fi 6E BAW filter with relative bandwidth of 12% (665 MHz at 5.5 GHz) and good rejection over the whole 6 GHz band (1200 MHz) is reported. The Wi-Fi 6E filters have much wider bandwidth than those of early Wi-Fi 5/6 filters. High coupling coefficient

Most current radio receivers use SAW bandpass filters for band selection. Their center frequency depends on the dimensions of the interdigital structure. Therefore, in the next few years, SAW technology will face some fabrication process limits because of the need of higher operating frequencies. BAW resonators are emerging as an alternative technology.

An Improved Formula for Estimating Stored Energy in a BAW Resonator by its Measured S11 Parameters
IUS, 2021In 2008, a formula was proposed to estimate the Time Averaged Stored Energy (TASE) in a bulk acoustic wave (BAW) resonator using only the measurement of its S11 parameters and the incident power [1].

BAW Filter Trends for 5G and Beyond
2024 IEEE International Microwave Filter Workshop (IMFW)Bulk acoustic wave (BAW) filters are a fundamental enabler of 5G wireless communication systems. RF-FEMs feature an ever-increasing number of filter paths that must manage a very crowded electromagnetic spectrum with minimum insertion loss, maximum out ...
