Problems solved by technology

These waveguide T-shaped branches have the following disadvantages: 1) Insufficient bandwidth
2) The direction of polarization is limited. For the ports A and B of the waveguide E-side T-shaped branch and the waveguide H-side T-shaped branch on the market, the electric field directions at the center of port A and port C are parallel to each other, which cannot make the output The direction of the electric field is rotated based on the direction of the input electric field
3) Phase limitation, the phases of port B and port C of the E-plane T-shaped waveguide branch and the H-plane T-shaped waveguide branch on the market cannot achieve a phase difference of 180 degrees within the full relative working bandwidth
4) Limited by miniaturization, the existing technology cannot match the full bandwidth of port A well in a small space

Embodiment 1

[0030] Such as figure 1 and 2 shown. The T-shaped HE plane branch includes a coupling cavity 1, a port A2, a port B3, and a port C4, and also includes three first-level matching sections 11. One end of the matching section 11 is connected to the coupling cavity 1, and the other end of the matching section 11 is connected to port A2 or port B3 or port C4.

[0031] The electric field direction at the center of the port A2 is perpendicular to the horizontal plane, while the electric field directions at the centers of the ports B3 and C4 are within the horizontal plane.

[0032] Port A2 is the input end; for the matching section 11 connected to port A2, there is a line segment AX that is located in the horizontal plane and connects a certain point in the coupling chamber 1 to another point on port A2, and the matching section 11 connected to port A2 and The maximum depth of port A2 in a plane perpendicular to the line segment AX is constant or increases monotonously along the ...

Embodiment 2

[0040] Such as image 3 and 4 shown. Compared with the implementation example 1, the difference of this implementation example is only that the normal direction of the port A2 is opposite to the normal direction of the port B3 and the port C4. Therefore, the T-shaped HE plane branch constitutes a compact Y-shaped waveguide power divider. At the same time, there is no need to bend the port B3 and the port C4, and the phase difference between the signals of the port B3 and the port C4 is already 180°. In addition, no metal pillar 5 is provided in this embodiment.

Abstract

The invention discloses a T-shaped HE face stub which comprises a coupling cavity, a port A, a port B, a port C and at least one one-stage or two-stage or multi-stage matching section. One end of the matching section is connected with the coupling cavity, and the other end of the matching section is connected with the port A or the port B or the port C. According to the T-shaped HE face stub, a compact wideband waveguide power divider is obtained, and particularly the electrical field direction of the center of the port A and the electrical field direction of the centers of two output ends can be reversed by 90 degrees; meanwhile, phase difference of signals of the two output ends can be kept at 180 degrees within the wideband range. The T-shaped HE face stub is simple and compact in structure, and capable of being integrally machined with other microwave components at a time conveniently, and becoming an important component of an integrated waveguide system; the T-shaped EH face stub has the advantages that up to 30% of phase pairs are used as the bandwidth, the machining and adjusting cost is low, the precision of width phases between the output ends is high, the input and output polarization directions are rotated, and the accurate 180-degree phase difference between the output ends is achieved.

Description

technical field [0001] The invention relates to a power divider, in particular to a compact broadband power divider with good amplitude and phase consistency. Background technique [0002] Power splitters are a common component in modern microwave communications and military electronic systems. T-branches are widely used due to their high power capacity and low insertion loss. T-shaped branches can be used alone, or can be connected in series to form a multi-channel power distribution network, which is used in the fields of phased array radar, antenna array, and power synthesis. The T-shaped branch can be in various transmission line forms, but the waveguide T-shaped branch is the most common. The existing waveguide T-shaped branches mainly include E-plane T-shaped branches and H-plane T-shaped branches. These waveguide T-shaped branches have the following disadvantages: 1) The bandwidth is insufficient. The relative operating bandwidth of the waveguide E-plane T-shaped ...
