Abstract

In this contribution, performances of a Class F-1 power amplifier are studied, highlighting their dependence on transistor bias point and input power level. First, a concise mathematical analysis is given, describing the drain current behavior. Theoretical assessments are validated through nonlinear measurements performed on a X-band MMIC PA in GaAs technology, which can achieve a peak efficiency of 54 % in correspondence of a saturated output power of 27 dBm.
