Abstract
Based on a Silicon carbide (SiC) Metal‐Semiconductor Field Effects Transistor (MESFET), a broadband VHF SiC class‐E high power amplifier is implemented by using a π‐transform output load network. Experimental results show that drain efficiency greater than 60% is achieved over a frequency bandwidth of 51.4%, and the peak output power exceeds 34 W. © 2009 Wiley Periodicals, Inc.
