A Miniaturized Multimodal Equalizer Based on Vector Synthesis

Abstract

The invention discloses a miniaturized multi-peak equalizer based on vector synthesis, which comprises a microstrip layer, a dielectric layer and a metal layer sequentially stacked from top to bottom, and the microstrip layer includes a first transmission main line and a second transmission main line , and a multi-level structure composed of the surface microstrip of the first-level power divider structure, the surface microstrip of the second-level power divider structure, the surface microstrip of the third-level power divider structure and the surface layer microstrip of the fourth-level power divider structure Power Distribution‑Synthesis Structure. The present invention utilizes a multi-stage power distribution-synthesis structure to realize multi-channel distribution and vector synthesis of microwave signals, and achieve equalization at multiple specific frequency points. Balanced volume while achieving miniaturization.

Description

technical field [0001] The invention belongs to the technical field of microwave gain equalizers, in particular to a miniaturized multi-peak equalizer based on vector synthesis. Background technique [0002] A microwave gain equalizer is a passive two-port network whose ultimate purpose is to absorb power at a specific frequency point. Structurally, it is generally composed of a main transmission line, a resonant unit and a trap composed of a microwave absorber. According to the presence or absence of bias power, equalizers can be divided into active and passive equalizers. Active equalizers are often adjustable equalizers, including adjustable equalization volume and adjustable frequency band, etc., and the structure is relatively complicated. Passive equalizers are easier to implement, and can usually be divided into two categories: one is the equalizer with cavity structure, and the common types mainly include waveguide and coaxial type; the other is the most widely use...
