Abstract

A measurement system combining vector corrected waveform measurements with active harmonic load-pull extends, for the first time, real-time experimental waveform engineering up to the 30 W power level. This novel harmonic load-pull approach is demonstrated on a 4 W LDMOS device. A 20% increase in maximum output power to 4.7 W without degrading gain and efficiency was realized.
