Abstract

See full text

The present invention discloses a matching circuit with switchable load lines, a load line switching method and a power amplifier. The matching circuit matches the output impedance of the power amplifier, which amplifies an input signal and outputs an amplified signal. The matching circuit comprises a filter circuit and a switch group for load line selection, the output end of the filter circuit is connected to the switch group. The switch group comprises at least two independent switches, each switch independently constitutes a signal line, and each switch is configured with an external control signal to control on/off. The matching circuit provided by the invention adopts a switch group composed of at least two independent switches, and each independent switch forms a signal line to connect loads, so that multiple loads can be connected at the same time.
