Novel bridge

Abstract

A novel electric bridge relates to the technical field of electric bridges. It consists of a lower cavity, an inner cover, and an outer cover. An inner cover is installed above the lower cavity, an outer cover is installed above the inner cover, and there is a waterproof groove between the inner cover and the lower cavity. Microstrip lines are arranged in the body, dielectric plates are respectively arranged above and below the microstrip lines, and additional dielectric boards are respectively arranged outside the dielectric boards. The invention not only has high power, can enter and exit at the same time, but also can intermodulate three media, and can be waterproof, which not only meets the functional requirements, but also reduces the production cost.

Description

Technical field: [0001] The invention relates to the technical field of electric bridges. Background technique: [0002] The frequency of the widely used 3dB bridge is between 800-2500MHz. With the development of technology, the requirements for communication technology are getting higher and higher. Passive products such as , attenuator, etc., not only use more DIN type couplers to increase power, but also put forward higher requirements such as three-media intermodulation, IP65 waterproof, etc., among which the bridge is the most obvious, and put forward a higher high Power, same input and output, three media intermodulation, IP65 waterproof and other requirements, but if all these requirements are realized in the 800-2500MHz bridge, it is difficult to achieve, because the high power is required, so the microstrip line design cannot be used, and the microstrip line design cannot be used. The metal thickness of the strip line is only 0.035mm, which is difficult to withstan...

Problems solved by technology

[0002] The frequency of the widely used 3dB bridge is between 800-2500MHz. With the development of technology, the requirements for communication technology are getting higher and higher. Passive products such as , attenuator, etc., not only use more DIN type couplers to increase power, but also put forward higher requirements such as three-media intermodulation, IP65 waterproof, etc., among which the bridge is the most obvious, and put forward higher high Power, same input and output, three media intermodulation, IP65 waterproof and other requirements, but if all these requirements are realized in the 800-2500MHz bridge, it is difficult to achieve, because the high power is required, so the microstrip line design cannot be used, and the microstrip line design cannot be used. The metal thickness of the strip line is only 0.035mm, which is difficult to withstand high power, and because of the requirement of the same input and output, the commonly used strip line structure bridge is not good, and the design of the columnar structure may not be sold at the price or even the cost. What's more, there are three intermodulation, IP65 waterproof and other requirements that need to be met
