Abstract

The invention provides a dual-frequency Wilkinson power divider, which comprises an input port, two output ports, and a first transmission line, a second transmission line and a third transmission line located between the input port and the output ports, wherein the input port is connected with one end of the first transmission line; and the other end of the first transmission line is divided into two paths, one path is connected with the first output port via the second transmission line, and the other path is connected with the second output port via the third transmission line. The dual-frequency Wilkinson power divider also comprises a stub and an RCL circuit, wherein the stub is in parallel connection onto the input port; the RCL circuit is connected between the first output port and the second output port; the RCL circuit is formed by a resistor and an LC circuit in parallel connection; the LC circuit is composed of a first capacitor, a second capacitor and an inductor; the first capacitor and the second capacitor are distributed at two sides of the inductor; and the first capacitor and the second capacitor have the same capacitance values.

Description

technical field [0001] The invention relates to a power divider in microwave communication, in particular to a miniaturized dual-frequency Wilkinson power divider based on an RCL circuit. Background technique [0002] With the rapid development of wireless communication technology, power splitters, as an important part of wireless communication systems, have attracted more and more attention. In particular, the application of dual-frequency devices is increasingly widespread, and many wireless communication standards are based on two or more frequency bands. Therefore, it is of great significance to study dual-frequency power dividers. [0003] Wilkinson power dividers have excellent isolation and good port matching, and are widely used in various microwave and radio frequency circuits. However, for the traditional Wilkinson power splitter, its bandwidth is single, which is not suitable for dual-frequency communication systems. The dual-frequency Wilkinson power divider pr...
