Broadband cavity double-power distributor achieving index taper line transmission

Abstract

The invention relates to a broadband cavity double-power distributor achieving index taper line transmission. The broadband cavity double-power distributor comprises an outer cavity and an inner conductor resonant rod embedded into the outer cavity. One end of the inner conductor resonant rod serves as a resonant rod input end and is connected with an input end contact pin. The other end of the inner conductor resonant rod serves as a resonant rod output end and is connected with a first output end contact pin and a second output end contact pin. According to the broadband cavity double-power distributor achieving index taper line transmission, the overall structure is compact, the length is small, machining is easy, the size and weight are small, and the production cost is low. The problems that a cavity power distributor in the prior art is long, poor in product consistency, large in machining difficulty, high in production cost, large in size and weight and the like are solved.

Description

technical field [0001] The invention relates to the field of cellular mobile communication, in particular to a broadband cavity-two power divider for exponential gradient line transmission. Background technique [0002] At present, most of the common broadband cavity power dividers on the market are formed by cascading multi-stage quarter-wavelength impedance converters, but the cavity power dividers produced and processed by this method are relatively long and require more energy consumption. More raw materials lead to higher production costs, and because the inner conductor is stepped impedance transformation, the production and processing of the inner conductor is more difficult, which reduces the production efficiency. Usually, if you want to achieve the coverage of the 800-2700MHz frequency band, it takes five A quarter-wavelength impedance converter is cascaded, and the total length of the product is generally more than 230mm, which greatly wastes materials and increas...

[0002] At present, most of the common broadband cavity power dividers on the market are formed by cascading multi-stage quarter-wavelength impedance converters, but the cavity power dividers produced and processed by this method are relatively long and require more energy consumption. More raw materials lead to higher production costs, and because the inner conductor is transformed in a stepped impedance, the production and processing of the inner conductor is more difficult, which reduces the production efficiency. Usually, if the coverage of the 800-2700MHz frequency band is to be achieved, it takes five A quarter-wavelength impedance converter is cascaded, and the total length of the product is generally more than 230mm, which greatly wastes materials and increases production costs.
