AD1582BRTZ_AD210BN 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Texas Instruments currently has 15 wafer fabs in 9 countries, of course, these plants include outdated capacity that is about to close, as well as new 300mm capacity.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Instruments' 150mm/200mm wafer fab (GFAB) in Greenock, Scotland, UK, as part of TI's strategy to gradually abandon outdated capacity.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. Taking Renesas as an example, the company's two recently closed fabs are both 150mm, including a factory in Kochi Prefecture, Japan, which mainly produces analog, logic devices and some old-fashioned micro components. From a regional perspective, Japan closed a larger number of fabs.

Professor Kerstin Mey, Vice-Chancellor of the University of Limerick, said: "ADI is our firm and strong long-term partner, and I am delighted that ADI is working with us on this exciting new project. We are looking forward to working with ADI to achieve this Important ways to reshape the way future software engineers are trained.”.

So, does this mean that 150mm wafers are gradually withdrawing from the stage of history? The answer is no, there is still a huge market space for 150mm wafers. A large number of 150mm fabs in the industry were closed, and more and more 300mm fabs were launched and gradually achieved mass production.

In order to gain an in-depth understanding of TI's new breakthrough in BAW technology, let's start with the principle of BAW filter: . • In the past, BAW resonator technology has been used to filter signals in communication technologies such as smartphones. For the first time in the industry, TI uses this technology for integrated clock functions.

Analog Devices leverages its unique domain application expertise to play an important role in end-use applications and positively impact customers' businesses. ADI's advances in software are deeply influencing how customers choose and use their solutions. .

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 technology, which also enables high-precision and robust communication between IoT devices, can now be developed in a less bulky form, said Kim Wong, vice president of high-speed data and clocking at TI.

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.

Wireless networks are at the heart of this data migration, and the ability to connect the last mile through connected devices is a key part of the data loop. "Making accurate, informed decisions through the use and analysis of large amounts of data is a very important innovation capability," said Ray Upton, vice president of TI's Interconnect Microcontroller Group.
