ENHANCED POWER AMPLIFIER EFFICIENCY THROUGH ELIMINATION OF MATCHING NETWORK

摘要

Enhanced power amplifier efficiency through elimination of matching network. In some embodiments, a power amplification system can include a power amplifier (PA) configured to receive and amplify a radio-frequency (RF) signal, and an output filter coupled to the PA by an output path that is substantially free of an impedance transformation circuit. The PA can be further configured to drive approximately a characteristic load impedance of the output filter. The PA being configured to drive approximately the characteristic load impedance of the output filter can be effectuated by the PA being operated with a high-voltage (HV) supply.
