The invention discloses a high-power wideband power divider, which comprises a microwave dielectric substrate. A microstrip line is arranged on one surface of the microwave dielectric substrate, and a grounding plate is arranged on the other surface of the microwave dielectric substrate. The microstrip line consists of two groups of symmetrical microstrip line sections (1). Each group of microstrip line sections (1) comprise five sections of 1 / 2 microwave microstrip lines (2) and four sections of 1 / 4 microwave microstrip lines (3). All the 1 / 4 microwave microstrip lines (3) and the 1 / 2 microwave microstrip lines (2) are equal in width, and have dumbbell shapes with thin middle parts and two thick ends. The thin middle part of each section of microstrip line is a nick (4) which is connected with a loading capacitor, and the other end of each loading capacitor is connected with the grounding plate on the other surface of the microwave dielectric substrate. The high-power wideband power divider has the characteristics of small size, light weight, simple structure, wideband, high isolation between output ends, high standing wave ratio, low power loss, high output power, no requirements for the connection of two output ports with a matched resistor, and the like, and is easy to machine.
Description
technical field [0001] The invention relates to a high-power wide-band power divider. Background technique [0002] The microstrip line design used by the popular power splitters in the market is generally composed of 12 equivalent quarter-wavelength microstrip lines and half-wavelength microstrip lines on each side. Wide, in line with the characteristics of microwave work. However, the microstrip power splitter with this structure has the following disadvantages: (1) the transmitted power is relatively small; (2) the output must be connected to a matching isolation resistor, otherwise the output standing wave will be very large; (3) the output must A matching isolation resistor must be connected, otherwise the isolation between the output ports cannot meet the parameters specified in the technical requirements: (4) It cannot be used as a combiner for small signals, because two signals with different phases will definitely burn out the matching isolation resistance, and ev...
