Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0022] Such as Figure 1-3 As shown, the structure diagram of the miniaturized equalizer based on LCP technology of the present invention has seven layers in total, including the metal ground layer 0, the first dielectric layer 1, the first metal layer 2, and the second dielectric layer stacked sequentially from bottom to top. Layer 3, second metal layer 4, third dielectric layer 5 and third metal layer 6. The first dielectric layer 1, the second dielectric layer 3, and the third dielectric layer 5 are all made of LCP and are provided with metallized through holes. The metal ground layer 0 , the first metal layer 2 , the second metal layer 4 and the third metal layer 6 are printed on the surface of the dielectric layer and form three LCP resonators together with the metallized through holes. The surface microstrip of the resonator is connected to t...

Abstract

The invention discloses an LCP technology-based small-sized equalizer which comprises a metal grounding layer, a first dielectric layer, a first metal layer, a second dielectric layer, a second metal layer, a third dielectric layer and a third metal layer that are orderly stacked from bottom to top; the first dielectric layer, the second dielectric layer and the third dielectric layer are all made of LCPs and are all provided with metalized via holes; the metal grounding layer, the first metal layer, the second metal layer and the third metal layer are printed on surfaces of the dielectric layers and form three LCP resonators via the metalized via holes; the resonators are connected with each other via a microstrip line equivalent structure. The LCP technology-based small-sized equalizer is advantaged by small size, large equalization quantity, and small insertion loss; the LCP technology-based small-sized equalizer is particularly suitable for adjusting power gain flatness of a large power travelling wave tube working in a low frequency range.

Description

technical field [0001] The invention belongs to the technical field of power devices, and in particular relates to a miniaturized equalizer based on LCP technology. Background technique [0002] The gain equalizer is used to solve the problem of uneven gain of the traveling wave tube amplifier. A better equalization effect is the prerequisite for the SSA to provide suitable driving power for the TWT, and it is also the guarantee for the good overall performance of the MPM. Gain equalizers are divided into microstrip type, waveguide type and coaxial type according to the transmission medium. Microstrip gain equalizer is composed of microstrip circuit, planar structure, light weight, small size, easy to integrate with solid-state circuit. This type of microwave gain equalizer can use microwave circuit simulation technology to carry out accurate and fast simulation, which greatly improves the design efficiency of the circuit and has high stability.
