English abstract:
We present a 15-W, 1-GHz harmonically tuned power amplifier (PA) with a power added efficiency (PAE) of 75%. The PA design is based on a packaged 50-V Si-LDMOS engineering sample. The PAE is maximized by an appropriate tuning of the fundamental and second harmonics, while the higher harmonics are shortened by the parasitic drain-source capacitance. The PA design is based on a simplified transistor model which is optimized for harmonically tuned PAs. The model parameters are extracted from IV- and S-paramter measurements of the packaged LDMOS device. A good agreement between the simulation and measurement results shows the accuracy of the modeling and PA design procedure.
