SFR9230BTM_GRM2165C1H911GA01D Introduction

With the advent of 5G networks and next-generation communications technology, many sectors from business to healthcare, agriculture and education will be affected. ?? Once communications infrastructure is in place to support the transfer of large amounts of data, businesses and governments will want to provide wireless coverage for point-to-point connections over the last mile, from objects communicating with each other in warehouses to communicating smartphones, thermostats, Between heart rate monitors and many other devices.

Accurate rhythm is achieved through crystal oscillation. But when these expensive crystals wear out, they can vibrate or jump, affecting the accuracy of timekeeping.

The 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.

Today, timing often requires a quartz crystal. In this case, BAW resonator technology offers TI a huge advantage by eliminating the need for external components mounted on the PCB. "Everyone uses quartz crystals for clocks," Solis said.

"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.

TI's new newer SimpleLink™ multi-standard MCUs with ?BAW technology can be integrated into low-power wireless RF devices, such as low-power crystalless Bluetooth and Zigbee? technology, thereby reducing wireless RF failures caused by external crystals.

?? There is also a method called FBAR (Film Bulk Acoustic Resonator), including Membrane type and Airgap type. ??Membrane Type is etched from the back of the substrate to the surface (that is, the bottom electrode surface) to form a suspended thin film and a cavity. .
