Embodiment Construction

[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0019] as attached figure 1 As shown, a single-pulse sum and difference device, the sum and difference device includes: a dielectric plate 13, a metal cavity 14, a mixing ring 1, a mixing ring 2, a mixing ring 3, and a mixing ring 4, and also includes: an open branch line 5. Open leg 6, Open leg 7, Open leg 8, Open leg 9, Open leg 10, Open leg 11, Open leg 12.

[0020] The metal cavity 14 is a square, the surrounding edges and the middle part are convex, and the rest is concave. The dielectric plate 13 is placed in the concave part of the metal cavity 14 to match the concave part. Mixing ring 1, mixing ring 2, mixing ring 3 , The mixing ring 4 is etched on the four corners of the dielectric plate 13 . The b-termin...

Abstract

The invention relates to a monopulse sum and difference network, which comprises a dielectric plate, a metal cavity, hybrid rings, a first open-circuit branch line and a second open-circuit branch line, wherein each hybrid ring at least comprises a first end, a second end, a third end and a fourth end; the first open-circuit branch line and the second open-circuit branch line are connected with the hybrid rings; one end of the first open-circuit branch line is in an open circuit and the other end is connected with the first end of one hybrid ring; and one end of the second open-circuit branch line is in an open circuit and the other end of the second open-circuit branch line is connected with the third end of one hybrid ring. The obtained sum and difference network is simple in structure; all circuits are located in the same plane, and are convenient to process and relatively small in volume; all external input and output interfaces are located in the same plane through installing a vertical joint; installation and fixation are convenient and the debugging workload is extremely low; and the monopulse sum and difference network can be directly used without debugging after being processed.

Description

technical field [0001] The invention relates to the technical field of summers, in particular to a single-pulse summer. Background technique [0002] The summer is widely used in the monopulse antenna system, and it is one of the most critical components in the antenna system. In recent years, with the rapid development of the solid-state monopulse phased array antenna, the planarization and miniaturization of the summer Higher requirements are put forward. The bandwidth of the summer in the traditional structure is narrow. After the bandwidth exceeds 5%, the amplitude and phase consistency of the transmission is poor, and the isolation is low, which makes it unusable in engineering. Contents of the invention [0003] The technical problem to be solved by the present invention is: the bandwidth of the current summator is narrow, and the consistency of the amplitude and phase of the transmission is poor when the bandwidth exceeds 5%, and the isolation is low, so it cannot b...
