Abstract

The invention discloses a double-open-loop miniaturized equalizer. The double-open-loop miniaturized equalizer comprises a micro-strip layer, a dielectric layer and a metal layer which are sequentially stacked from top to bottom; the micro-strip layer further comprises a first double-open-loop resonator and a second double-open-loop resonator with the same structure; one end of a first open ring surface micro-strip is connected with a first resistor, and the other end of the first open ring surface micro-strip is of an open ring structure; the circle center of the open ring structure of the first open ring surface micro-strip and the circle center of the open ring structure of a first inner open ring surface micro-strip are located at the same point; and one end of the first inner open ring surface micro-strip is connected with the metal layer, and the other end of the first inner open ring surface micro-strip is of an open ring structure. According to the double-open-loop miniaturizedequalizer provided by the invention, a novel resonant structure is adopted as a resonant unit of the double-open-loop miniaturized equalizer, the structure is simple and the size is small; since thestructure has a lot of variable parameters, the double-open-loop miniaturized equalizer is more flexible than a traditional transmission line structure resonator, and can realize a complicated equalization curve; and besides, the double-open-loop miniaturized equalizer has a larger equalization amount and a large bandwidth.

Description

technical field [0001] The invention relates to the technical field of equalizers, in particular to a miniaturized equalizer with many structural variable parameters and capable of realizing complex equalization curves. Background technique [0002] The power gain equalizer is a two-port network that produces specific attenuation of the input signal at different frequencies. It is generally used to correct the output power of the previous stage to adapt to the uneven gain curve of the high-power device in the subsequent stage. It is used in microwave communications and radar It plays an important role in systems such as transmitters. [0003] In the prior art, the equalizer is generally composed of a microstrip resonator and a resistor, and has a relatively complete circuit topology and design steps. For the traditional uniform impedance resonator (UIR) and step impedance resonator (SIR), it is usually composed of simple microstrip stubs. This structure design is simple and...
