WSE: Advanced BAW-enabled wireless transceivers: From devices to system architecture

Bulk Acoustic Wave (BAW) resonators are now being used in functions such as filters or duplexers, namely for US-based PCS system. Key-advantages of this technology are reduced size and cost at good performance. This workshop will discuss recent advances in the technology and at the device level, such as zero temperature drift, multiple frequency bands on the same wafer, improved power durability, and increased quality factors. Combined with advanced packaging technologies, modules with high functionality can be realized. Beyond replacing other filtering technologies, BAW technology can have a significant impact on system architectures, and will allow novel approaches namely for low power radios. BAW resonators also have a strong potential as high-precision frequency references where they could advantageously replace quartz resonators for this purpose. All these points, as well as design tools and methodology, will be described by the speakers in this workshop.
