    摘要： A transit structure of a standard waveguide and a dielectric waveguide is related to connecting the dielectric dielectric waveguide to the standard waveguide. The transit structure includes: a cavity to match the dielectric waveguide and the standard waveguide, wherein the dielectric waveguide and the standard waveguide are orthogonal to each other to connect. The transit structure drastically reduces a design time by simply implementing a transit structure by using only a dielectric waveguide, a cavity and a standard waveguide on a dielectric substrate and remarkably reduces a size thereof in comparison with a conventional transit structure since all designs are finished in the size of a metal waveguide.

    摘要： Provided is a digital predistortion linearizer applicable to millimeter-wave band point-to-point communications. The digital predistortion linearizer includes a transmission unit and a reception unit. The reception unit receives a first signal including a transmission signal and a distortion signal through a millimeter-wave propagation environment, detects the distortion signal from the first signal, and transmits information on the detected distortion signal with the first signal to the transmission unit. The transmission unit generates a predistortion signal using the information on the distortion signal and the first signal received from the reception unit, couples the generated predistortion signal with the transmission signal, and outputs the coupled signal.
