An Ultra Wide Band Power Divider/combiner Based On Radial Waveguide
In this paper, an improved 1:8 power divider divider//combiner based on radial waveguide is proposed at ka-kaband. band. To widen the bandwidth of the divider divider//combiner combiner,,,, aaaannnn axially symmetric oversized coaxial waveguide is used to transform input to the radial waveguide, and at the bottom of the radial waveguide waveguide,,,, stepped-impedance technology is used to realize the impedance match match.... According to EM simulation simulationssss,,,, the simulated 20-dB return-returnloss loss bandwidth is approximately 42.4 42.4%%%% (ranging from 26 to 40 GHz), and good amplitude imbalance and phase imbalance are observed in the whole Ka band band.... FFFFurthermore, urthermore, the isolations between the peripheral ports are also discussed. TTTThis his structure has properties of not only aaaa wide band, low insertion loss and high output power, but also aaaa small size, aaaa high power combining efficiency and efficient heat sinking, and has potential for millimeter-wave broad-band high power combination.
