Abstract

The invention discloses an identical system circuit combiner with high-isolation degree, aiming at providing the identical system circuit combiner with high-isolation degree, which has simple structure and lower cost and is easy for processing. The identical system circuit combiner with the high-isolation degree comprises at least three medium plates and two coupling wires, wherein the coupling wires are clamped between the two medium plates with different dielectric constants; a layer of medium plate is clamped between the two coupling wires; the coupling wires are provided with micro-strip thin wires; one end of each micro-strip thin wire is connected with each coupling wire and the other end of the micro-strip thin wire is suspended. The transmission phase speeds of odd modules and even modules can be adjusted by mixing different medium materials and adding the micro-strip thin wires to the coupling wires, and the port isolation degree of the identical system circuit combiner is improved.. The invention is suitable for all dual-output port circuit combiners.

Description

technical field [0001] The invention relates to a combiner, in particular to a combiner with high isolation and the same system. Background technique [0002] The same system combiner is a device that mixes the energy of two signals and divides them into two outputs with equal or unequal energy. It is generally used for [0003] The main technical parameters of the combiner in the same system include power loss (including insertion loss, distribution loss and reflection loss), voltage standing wave ratio of each port, isolation between power input ports, power capacity and operating frequency bandwidth, etc., among which the power The isolation between input ports is a very important indicator. [0004] The State Intellectual Property Office of the People's Republic of China published a patent document whose publication number is CN1988248A on June 27, 2007. The name is a combiner, which includes a cavity filter and a microwave circulator. The electromagnetic wave energy c...
