Embodiment Construction

[0021] In order to facilitate those skilled in the art to understand the technical content of the present invention, the content of the present invention will be further explained below in conjunction with the accompanying drawings.

[0022] The present invention provides a method for power synthesis / distribution of high-power multi-channel equal-power equal-phase input signals. By adopting a design method of separating openings at equal intervals at the fan-shaped ends of the E-plane sector waveguides, multiple equal-power and equal-phase multiplexers can be realized. The function of combining or distributing the power of high-power signals.

[0023] The E-plane sector waveguide power combiner is actually a special form of radial power combiner. figure 1 shown. figure 1 , the xyz coordinate system is the coordinate system with the center of the circle that forms the fan as the origin, x', y', z' are the coordinate system with the midpoint of the fan terminal as the coordinat...

Abstract

The invention discloses a high-power equal-power equal-phase multi-path power synthesis / distribution method and a synthesis / distributor, which are applied to the field of power synthesizers and distributors, and are used for solving the problems of high insertion loss and unstable high-power transmission of the existing device. The circle center section of the sector of the E-plane sector waveguide is connected with the rectangular waveguide to serve as an input / output port, the sector end of the E-plane sector waveguide is separated at equal intervals in the direction parallel to the radial direction, and a plurality of openings with the same number as synthesis or distribution paths can be obtained; and the function of power synthesis or distribution of equal-power and equal-phase multipath high-power signals is realized.

Description

technical field [0001] The invention belongs to the field of power combiners and distributors, and particularly relates to an equal-power equal-phase multi-path power combining / distributing technology. Background technique [0002] In radar, communication and electronic countermeasures and other equipment, there are often problems of power synthesis and distribution. Power synthesis can not only improve the transmission power, increase the detection and action distance, but also realize the normalized transmission of multi-channel signals (shared antennas). ) and signal combining in diversity reception. Power combiners are mainly divided into two categories: waveguide cavity type and microstrip type. Among them, the waveguide cavity type combiner has the advantages of lower loss, higher power capacity and wider operating bandwidth, and is widely used in radar, satellite. and other high-power systems. However, this type of power combiner is often bulky and expensive to manu...
