AD1836AASZRL_AD28MSP02BN Introduction

Texas Instruments currently has 15 wafer fabs in 9 countries, of course, these plants include outdated capacity that is about to close, as well as new 300mm capacity. In April 2019, Diodes completed the acquisition of Texas Instruments' 150mm/200mm wafer fab (GFAB) in Greenock, Scotland, UK, as part of TI's strategy to gradually abandon outdated capacity.

It is reported that Renesas expects to close two more 150mm fabs in 2020 or 2021. In addition, Renesas has adjusted its factory in Otsu, Shiga Prefecture, Japan, to manufacture optoelectronic devices. Take Renesas as an example. The company's two recently closed fabs are both 150mm, including a fab in Kochi Prefecture, Japan, which produces analog, logic devices and some obsolete micro components. From a regional perspective, Japan closed the largest number of fabs.

The most basic structure of the BAW filter is that two metal electrodes sandwich a piezoelectric film (the thickness of the Quartz substrate is 2um at 2GHz), and the acoustic wave oscillates in the piezoelectric film to form a standing wave.

Vincent Roche, President and CEO of Analog Devices, said: "ADI is committed to enhancing the impact of software development on various industries and, with its unique strengths, bridging the real and digital worlds. We deeply appreciate ISE and others. Such projects are of great significance to help develop future software engineers.”

Flexible VIN broadens application range: The TPS62840 has a wide input voltage range of 1.8VIN-6.5VIN and accepts a variety of chemistries and configurations, such as two lithium-manganese dioxide (2s-LiMnO2) cells in series , single-cell lithium thionyl chloride (1xLiSOCL2) batteries, four- and two-cell alkaline batteries, and lithium polymer batteries (Li-Po).

In addition to these features, the C2000 F2838x microcontrollers offer enhanced real-time control performance and greater flexibility than previous generation C2000 series microcontrollers. For more information on the F2838x family of microcontrollers, .

In short, advances in BAW technology have brought "higher performance, simpler design, lower cost and smaller size" to wired and wireless networks, Wong explained.

"The new BAW resonator technology is important because TI is integrating it into its silicon products, reducing design time, solution size and component cost," said Philip Solis, research director for connectivity and smartphone semiconductors at IDC.

The reflector consists of several layers of alternating high and low impedance layers. For example, the first layer has a large acoustic wave impedance, the second layer has a small acoustic wave impedance, and the third layer has a large acoustic wave impedance, and the thickness of each layer is λ/4 of the acoustic wave, so that most of the wave will be reflected back and superimposed with the original wave. The overall effect of this structure is equivalent to contact with air, and most of the sound waves are reflected back. This structure is called BAW-SMR (Solidly Mounted Resonator), as shown below. One way is to form a Bragg reflector under the oscillating structure to reflect sound waves into the piezoelectric layer.

Only the ladder type and lattice type are briefly introduced here. The BAW filter can connect multiple resonators according to a certain topology. There are many types of BAW filters, including ladder type filter, lattice type filter, stacked crystal filter and coupled resonator filter.
