An Ultra-Wideband High Power Miniaturized Power Splitter

Abstract

The invention discloses a UWB (ultra wide band) high-power miniature power divider, and the power divider comprises a multi-stage air stripline network, a metal separator plate, and a multi-stage microstrip network. The multi-stage air stripline network comprises a first impedance matching conversion part. The multi-stage microstrip network comprises a dielectric plate, and the lower end face of the dielectric plate is provided with a microstrip layer. The microstrip layer is provided with two second impedance matching conversion parts, and the two second impedance matching conversion parts are distributed at two sides of the first impedance matching conversion part, and are connected with the first impedance matching conversion part through a vertical transition. The vertical transition comprises a rectangular metal plate and a metal cylinder. The metal plate is bent to form a right angle, and the vertical transition passes through the metal separator plate and the dielectric plate, and is connected with the first and second impedance matching conversion parts. The power divider is advantageous in that the vertical transition enables the multi-stage air stripline network and the multi-stage microstrip network to be connected for combined use, so as to meet the UWB, high-power and miniature requirements of the power divider.

Description

technical field [0001] The invention relates to the technical field of ultra-wideband power distribution and synthesis network in wideband radar, communication and electronic countermeasure systems, in particular to an ultra-wideband high-power miniaturized power divider. Background technique [0002] Ultra-wideband power splitters are widely used in military and civil electronic systems such as broadband radar, electronic countermeasures, and broadband communications. As power splitters for energy synthesis and distribution, there are currently three main forms: air board line network form, micro Band network form and waveguide form, the waveguide form power divider bears high power but the volume and weight are too large, and it is difficult to realize the octave ultra-broadband design; the air board line network form power divider is also too large in volume and weight; and the micro The power divider with network form is difficult to withstand high power, and the simple ...
