摘要
In this letter, a method for widening impedance matching spaces of power amplifier is proposed by expanding the voltage and current equations of class F power amplifiers. The proposed method can improve design flexibility and convenience of broadband power amplifiers while maintaining high output power and drain efficiency. To verify this theory, a power amplifier from 1 GHz to 3.5 GHz is designed. The measured experimental results show that the drain efficiency can reach 50.6%-63.4%, the output power is greater than 40 dBm, and the gain is greater than 10 dB.
