Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] Based on modern high-precision processing technology, the invention innovatively proposes a new type of amplifier design circuit, which introduces a metal ridge from the wide side of the rectangular waveguide, and realizes the transformation from the rectangular waveguide to the coplanar waveguide with the cooperation of the resonant cavity and the metal sheet. Lossless conversion of field modes. The input and output of the amplifier chip cooperate with the above circuit form to form an amplifier with a rectangular waveguide as the transmission line. The amplifier circuit is all metal struct...

Abstract

The invention is applicable to the technical field of amplifiers and provides a dielectric-free high-frequency extensible-broadband high-performance waveguide amplifier. The waveguide amplifier comprises an upper cavity, sheets and a lower cavity which are integrated, wherein the sheets are positioned between the upper cavity and the lower cavity. A metal ridge is formed on wide sides of the lower cavity, and the metal ridge and the sheets form an imbalance-to-balance conversion structure, so that conversion from a waveguide field mode to a coplanar waveguide field mode is achieved. The waveguide amplifier has the advantages that bad influences such as dielectric loss, resonance and the like caused by dielectric substrates can be eliminated completely, performances of the millimeter wave amplifier designed based on a circuit are improved greatly, and particularly, the higher the frequency is, the more obvious the advantages displayed by the amplification circuit are.

Description

technical field [0001] The invention belongs to the technical field of amplifiers, in particular to a medium-less high-frequency scalable broadband high-performance waveguide amplifier. Background technique [0002] With the rapid development and wide application of millimeter-wave technology in the fields of imaging, radar, electronic countermeasures, and radiometers, the demand for high-performance millimeter-wave solid-state amplifiers is becoming more and more urgent. Broadband millimeter-wave solid-state power amplifiers are used as millimeter-wave transmitters An important part of the front end, its importance is self-evident. At the same time, with the rapid development of radar, electronic countermeasures and wireless communication technologies, higher requirements are placed on the technical indicators of solid-state amplifiers in terms of broadband operating characteristics, efficiency, and high performance. Such as higher operating frequency, wider bandwidth, bet...
