First Pass Design Methodology for a Broadband 100 W RFPA

Presented by: Jack Brunning, SARAS Technology

Hosted by: National Instruments

This webinar presents a design methodology for a broadband RF power amplifier (RFPA) for continuous wave (CW) operation using load pull for optimal impedance extraction, network synthesis, and electromagnetic analysis. Requirements for the amplifier were a minimum output power of 80 W over the operating bandwidth while maintaining saturated power flatness across the band. The design uses a commercially available packaged GaN on SiC device and the integrated design flow within NI AWR Design Environment, specifically Microwave Office, to produce a first-pass reference design.
