Applied RF and Wireless Design - Products and Systems
*Revised and updated with new content for 2013* Course Overview In today’s ultra-competitive global wireless industry, the design-to-production cycle is of crucial importance. However, developing modern wireless products on time and to budget that meet specification presents many challenges. Advanced skills and knowledge are required not only to architect these systems and devise suitable circuit topologies, but also to solve the challenging integration and manufacturability issues. This revised and updated 3-day technical course focuses on the practical design and development of modern RF and wireless communications circuits and systems using common digital modulation standards such as GSM, 3GPP, LTE, Wi-Fi, WiMAX, Bluetooth and GPS. The course teaches both the theoretical and practical aspects of developing robust RF and wireless designs suitable for high-volume production.
Who Will Benefit? The technical course is aimed at engineers, technicians and engineering managers working in the wireless communications industry. The audience typically includes RF engineers and technicians working in research and development, manufacturing test and production environments and systems engineers responsible for the architecture of RF communications systems. The course will also be of interest to technical managers who oversee these groups.
