DIN type intermodulation waterproof electric bridge

Abstract

The invention discloses a DIN type intermodulation waterproof electric bridge, relating to the electric technology field. The DIN type intermodulation waterproof electric bridge consists of a lower cavity, an inner cover plate and an outer cover plate. An inner cover plate is arranged above the lower cavity body; the outer cover plate is arranged above the inner cover plate; a waterproof groove is arranged between the inner cover plate and the lower cavity; a microstrip line is arranged inside the cavity; the upper side and the lower side of the microstripe are provided with medium plates; and the outside of the medium plates are provided with additional medium plates. The DIN type intermodulation waterproof electric bridge disclosed by the invention is high in power, and can enter and exit at the same time, third-order intermodulation and waterproof function can be achieved, so that functional requirements are satisfied, and the production cost is also lowered.

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
