Abstract

The utility model provides the technical scheme of a ferrite switch, and the scheme is a ferrite switch. The ferrite switch comprises a switch body, and the switch body is in an arc structure. A first I/O port and a second I/O port are symmetrically arranged on both ends of the switch body, and the two ports are connected in parallel. A bilateral hollow channel is arranged on the outer side of the switch body. A number of ferrite magnetic cores are arranged in the inner side of the switch body. Each ferrite magnetic core is respectively and correspondingly provided with a set of incentive terminals. The incentive terminals are arranged above the hollow channel. Radiation ports are arranged on the arc inner side wall of the switch body. Opening inner threads are arranged on left and right sides of each radiation port. Pins are arranged at the middle parts of upper and lower ends of each radiation port. The ferrite switch can keep the same insertion loss value, and can reduce the insertion loss value at the same time.

Description

A kind of ferrite switch

Technical field

The utility model relates to a kind of switch/inlet structure, especially a kind of ferrite switch.

Background technology

In the prior art, known technology is that the mirror multi-beam antenna there is no concrete application at home, also only has in the world the U.S. that matured product is arranged.In most lens multi-beam antenna feeding networks, each radiation port Insertion Loss difference is large, and the wave beam consistency is bad, and this is the existing weak point of prior art.

The utility model content

The purpose of this utility model is exactly for the existing deficiency of prior art, and a kind of ferrite switch technical scheme is provided, this scheme adopts arc-shaped structure, two I/O port correspondences are positioned at switch body two ends and are connected in parallel, and can keep identical Insertion Loss value, can also reduce the Insertion Loss value simultaneously.

This programme is achieved by the following technical measures: a kind of ferrite switch, include switch body, and switch body is convex structure; The switch body two ends are symmetrically arranged with an I/O port and the 2nd I/O port, and two-port is connected in parallel; The switch body arranged outside has symmetrical hollow channel; The inboard inside of switch body is provided with a plurality of FERRITE CORE; Each FERRITE CORE correspondence separately is provided with one group of stimulation terminal; Stimulation terminal is arranged on above hollow channel; The arc madial wall of switch body is provided with the radiation port; The radiation port left and right sides is provided with the opening internal thread; The middle part at two ends, radiation port up and down is provided with pin.

Preferred as this programme: an I/O port and the 2nd I/O port are the waveguide flange structure.

The beneficial effect of this programme can be learnt according to the narration to such scheme, because switch body two ends in this scheme are symmetrically arranged with an I/O port and the 2nd I/O port, two-port is connected in parallel, with respect to being connected in series, when the radiation port number was even number, its maximum Insertion Loss was reduced to (N/2-1) * η by original N * η; When the radiation port number was odd number, its maximum Insertion Loss was reduced to (N-1)/2 * η (wherein N is the radiation port number, and η is single FERRITE CORE Insertion Loss) by original N * η, and this structure can also guarantee the consistency of a port Insertion Loss value simultaneously.

This shows, the utility model compared with prior art each port Insertion Loss value consistency is better, and the Insertion Loss value is lower, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.

Embodiment

For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.

Can find out by accompanying drawing, in the ferrite switch of this programme, an I/O port and the 2nd I/O port are symmetrical, consist of parallel way, and its version is waveguide flange; For the FERRITE CORE 9 in the left and right sides, switch body center consists of respectively series system.The cable of stimulation terminal 2 is wound around on FERRITE CORE 9 by rule, by applying direct impulse for stimulation terminal 2, can realize respectively the conducting of an I/O port and left side radiation port and the conducting of the 2nd I/O port and right side radiation port, transmission and the transmission from two I/O port to right side radiation port of settling signal from an I/O port to left side radiation port respectively, when described stimulation terminal 2 is applied reverse impulse, can realize respectively the reverse transfer of signal.
