An embodiment of the invention provides a synchronic multi-frequency power amplifier circuit with a multi-port frequency division output function. The synchronic multi-frequency power amplifier circuit comprises a substrate, a power amplifier circuit, a harmonic tuning and matching network and an output port of each branch circuit, wherein the power amplifier circuit is arranged on the top layer of the substrate and is used for transmitting a radio frequency signal of the present branch circuit and reflecting preset radio frequency signals of other branch circuits through an adjacent-frequencyopen-circuit network, and the length of an open-circuit branch circuit in the adjacent-frequency open-circuit network is a numerical value of a quarter-wavelength of the preset radio frequency signals of the other branch circuits; the harmonic tuning and matching network is used for adjusting the harmonic impedance of the radio frequency signal of the present branch circuit, and matching the impedance of the output port of the present branch circuit to the optimal impedance required by a transistor to obtain an adjusted radio frequency signal; and the output port of each branch circuit is used for outputting one path of adjusted radio-frequency signal serving as one path of single-frequency signal.
Description
technical field [0001] The invention relates to the field of electrical technology, in particular to a synchronous multi-frequency power amplifier circuit with multi-port frequency division output function. Background technique [0002] In recent years, the development of communication technology has become more and more rapid, and the application of communication has become more and more diversified. Therefore, people's demand for communication has increased rapidly, especially mobile communication. As the status of mobile communications is increasing, people have higher and higher requirements for the utilization of spectrum resources. Therefore, this presents new challenges for radio frequency systems. The radio frequency system can implement an electronic device to wirelessly transmit data with another electronic device and / or network through radio frequency signals. [0003] The power amplifier is an important energy conversion and power output device in the radio fre...
