摘要

随着新的5G无线通信标准即将到来，新的和以前未使用的频段将被引入，频率最高可达6 GHz。BAW滤波器由于其严格的保护带和陡峭的排斥要求，在支持这些波段方面起着至关重要的作用。本文将详细阐述基于5.2GHz滤波器设计的过程和设计挑战。

Process and Design Challenge for SMR-type Bulk Acoustic Wave (BAW) Filters at Frequencies Above 5 GHz

With the new 5G wireless communication standard on the horizon, new and formerly unused bands will be introduced with frequencies up to 6 GHz. BAW filters play a crucial role supporting those bands due to their tight guard-band and steep rejection requirements. This paper will elaborate on process and design challenges based on a 5.2GHz filter design.
