Abstract

The invention discloses an ultra-wideband sum-difference device, which comprises a dielectric substrate and a conductor layer arranged on the dielectric substrate, wherein the conductor layer is provided with a sum-difference circuit, and the sum-difference circuit includes two coplanar waveguide T-shaped branches, two coplanar waveguide-slot line T-shaped branches and four coplanar waveguide-slotline transitions; the two coplanar waveguide T-shaped branches and the two coplanar waveguide-slot line T-shaped branches are arranged at intervals and mutually connected to enclose into a closed area, and one coplanar waveguide-slot line transition is connected between the adjacent coplanar waveguide T-shaped branch and the coplanar waveguide-slot line T-shaped branch. The ultra-wideband sum-difference device can achieve good standing wave, amplitude and phase characteristics and large sum-difference isolation close to the octave.

Description

technical field [0001] The invention relates to the technical field of microwave devices. More specifically, it relates to an ultra-wideband summator. Background technique [0002] Summers are widely used in 0° and 180° power distribution or synthesis, such as balanced mixers, amplifiers, etc. The summator is also one of the key components of the monopulse system radar. With the development of technology, higher requirements are put forward for the broadband and miniaturization of the summator. The traditional planar summer is generally composed of a ring bridge, and the bandwidth is limited by the length of the ring, and the bandwidth is generally narrow. Contents of the invention [0003] An object of the present invention is to provide an ultra-wideband summer to solve the problem that the current summer has a narrow bandwidth and cannot be applied in the ultra-wideband. [0004] To achieve the above object, the present invention adopts the following technical solut...
