Abstract

The invention discloses a broadband ridge waveguide power synthesizer based on a gradient ridge and a power synthesizer device. The synthesizer has a compact structure, large bandwidth, low insertionloss and high bearing power and can realize higher power synthesis output. The broadband waveguide power synthesizer comprises a ridge waveguide which is composed of an upper cavity, a ridge cavity and a lower cavity, a first port which is arranged at one end of the ridge waveguide, a second port which is arranged at the other end of the ridge waveguide, a third port which is arranged at the frontend of the ridge waveguide and the gradient ridge, an penetrating ridge and a chamfered ridge which are arranged in the ridge cavity.

Description

technical field [0001] The present disclosure relates to the technical field of power combining, in particular to a wideband ridge waveguide power combiner based on tapered ridges and a power combiner device. Background technique [0002] Traditional power combining technologies include planar power combining technology and spatial power combining technology. Planar power combining technology is mainly based on microstrip planar circuit; space power combining technology can be divided into two types based on waveguide structure and coaxial structure. Due to the inhomogeneity of the radially symmetrical distribution of the fundamental electromagnetic field of the coaxial transmission structure, the field strength near the inner conductor is relatively large. At the same time, due to the narrow space for electromagnetic wave transmission between the inner and outer conductors, and the The existing dielectric loss leads to a small carrying power, and the concentration of the f...
