Abstract

The design methodology and measured performance of a broadband UHF class‐F power amplifier is presented and compared to that of a typical narrowband class‐F design. The realized broadband circuit achieves 65% of power‐added efficiency with 21 ± 0.5‐dBm output power from 575 to 915 MHz, corresponding to a relative bandwidth of 45%. © 2005 Wiley Periodicals, Inc. Microwave Opt Technol Lett 44: 243–247, 2005; Published online in Wiley InterScience (www.interscience.wiley.com). DOI 10.1002/mop.20599
