Abstract

The invention discloses a Wilkinson power divider with a harmonic suppression function. The Wilkinson power divider with the harmonic suppression function comprises a dielectric layer, wherein one side of the dielectric layer is adhered with a signal metal layer, and the other side of the dielectric layer is adhered with a metal ground layer; and the signal metal layer comprises a microwave transmission branched circuit, a second harmonic suppression branched circuit, a third harmonic suppression branched circuit, a fourth harmonic suppression branched circuit and an isolating resistor. The invention is used for the Wilkinson power divider.

Description

Technical field: [0001] The invention relates to a Wilkinson power splitter with harmonic suppression function. Background technique: [0002] In most microwave radio frequency systems, power dividers have a wide range of application scenarios, such as microwave power sensors, mixers, phase detection, and TR components, and many other circuits. [0003] In power splitter design, the most commonly used power splitter is Wilkinson power splitter. Because it has better broadband characteristics and lower insertion loss, it is widely used in practice. However, the Wilkinson power splitter itself has a shortcoming, its harmonic suppression ability and anti-spurious interference ability are poor, so if the Wilkinson Wilkinson power splitter is taken as an example, the Wilkinson Wilkinson power splitter is generally used , basically the circuit needs to add a band-pass filter in front of the input or add a low-pass filter after each port of the output to eliminate unwanted interf...
