DIN type high intermodulation waterproof electric bridge

Abstract

The invention discloses a DIN type high intermodulation waterproof electric bridge and relates to the technical field of electric bridges. The DIN type high intermodulation waterproof electric bridge is formed by a lower cavity, an inner cover plate and an outer cover plate, wherein the inner cover plate is arranged above the lower cavity, the outer cover plate is arranged above the inner cover plate, a waterproof groove is formed between the inner cover plate and the lower cavity, a micro-strip line is arranged in the lower cavity, dielectric slabs are arranged above and below the micro-strip line respectively, and additional dielectric slabs are arranged on the outer surfaces of the dielectric slabs respectively. The DIN type high intermodulation waterproof electric bridge has a high power, achieves in and out simultaneously, reaches three-dielectric intermodulation, can resist water, and not only meets functional requirements but also reduces 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 with...

[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
