The quatrter-wavelength line radio frequency lightning protection device is a kind of traditional lightning protection device.For many years, it bears the power height with simple in structure, and lightning protection effect is good, dependable performance, and non-maintaining characteristics extensively are used for various radio-frequency receiving-transmittings in a large number and penetrate system.In recent years, along with developing rapidly of communication science and technology and market, radio system has not been some frequency or narrowband systems in the past, generation be multiband and broadband system, the high power feed system.Like this, the weakness of traditional quatrter-wavelength line radio frequency lightning protection device just shows especially out.Because the present transmitting-receiving conllinear of communication system, cause up and downstream signal between can produce intermodulation product.Conventional filter construction lightning protection device is difficult to accomplish low intermodulation value.Most below 150dBc (43dBm*2), the product price that reaches this value is very high, and the product percent of pass is only less than 80%, along with the rising of communication frequency, and the more difficult raising of intermodulation value.
Summary of the invention
The purpose of this utility model is in order to solve the shocking preventing technology problem in multiband and the broadband radio frequency microwave system, and problems such as feed protection, low intermodulation value, and a kind of quarter-wave line terminal open circuit radio frequency lightning protection device for compensation is provided.
The purpose of this utility model is achieved in that the utility model comprises outer conductor, in described outer conductor, be provided with 50 ohm of coaxial lines of input, the input insulator, input compensating coaxial line, the quarter-wave branch line, the reference-junction compensation coaxial line, 50 ohm of coaxial lines of output insulator and output, 50 ohm of coaxial lines of described input link to each other through the support of input insulator and with input compensating coaxial line, the other end of input compensating coaxial line is connected with the reference-junction compensation coaxial line with the quarter-wave branch line respectively, 50 ohm of coaxial lines of the other end of reference-junction compensation coaxial line and output link to each other, 50 ohm of coaxial lines of output support through the output insulator, are provided with gap or gas discharge tube between the other end of described quarter-wave branch line and the outer conductor.
Compensating coaxial line of input described in the utility model and reference-junction compensation coaxial line can adopt the more piece transmission line section to compose in series.With the raising of complex structure degree, exchange bandwidth of operation for and further widen, simultaneously can feeding DC.
The utility model can be provided with structure interval electric capacity on described reference-junction compensation coaxial line.The protection level can be reduced, but feed can not be led to.
The utility model is repaid when being provided with structure interval electric capacity on the coaxial line at described output, can be provided with the direct current output interface at the end of described quarter-wave branch line, thereby can lead to feed.
Technique effect of the present utility model is: the utility model can provide on the basis of feed protection, guarantees high intermodulation value, reaches 160dBc, and percent of pass can reach more than 98%.Conventional quatrter-wavelength line radio frequency lightning protection device but can't be the power consumption equipment feed on top, base station, and this product has also increased the function that can lead to feed except that the characteristics that contain conventional quatrter-wavelength line radio frequency lightning protection device.Can reduce the system wiring cost with protection radio-frequency apparatus and power supply unit, improve device sensitivity.
