Document Type and Number:
Japanese Patent JP7264327
Kind Code:
B2
Abstract:
The present invention discloses an impedance matching circuit and method. The circuit is applied to a power supply circuit of an envelope tracking radio frequency power amplifier. An envelope tracking power supply is connected with a radio frequency power amplifier through a first matching circuit. The envelope tracking radio frequency power amplifier obtains the optimal efficiency by performing matching according to an optimal efficiency load impedance of the envelope tracking power supply and a conjugate impedance of an optimal efficiency load impedance of the radio frequency power amplifier.
