Portable Wireless Products Drive Filter Miniaturization (.PDF Download)

June 2, 2015

The arrival of new wireless standards and their narrowly spaced channels has filter manufacturers scrambling to enhance the performance and footprint of high-quality-factor (high-Q) surface-mount filter technologies. These performance requirements push the limits of discrete, surface-acoustic-wave (SAW), and bulk-acoustic-wave (BAW) filters, forcing filter manufacturers to look to other technologies to meet the needs of handset providers. In pursuit of advanced filter technologies, manufacturers are developing enhanced temperature-coefficient SAW/BAW devices, complete CMOS RF front-end solutions, and RF microelectromechanical-system (MEMS) filters...
