    The 6G race has already begun, and many countries and giant corporations started directing significant efforts and funds towards the development of the future technology. The 6G standard is expected to migrate to higher bands of frequencies to support wider bandwidth. Through this wide bandwidth, it will be feasible to serve the expected massive number of users and future applications, such as virtual reality and HD realtime transmission. One major problem in high frequency ranges, such as mm-wave bands, is the high signal attenuation, which can be compensated through more efficient amplifier systems. In this paper, we propose a wideband amplifier design fed through a Ridge Gap Waveguide line. The proposed design has many advantages inherited from the host guiding structure. The signal is carried by a Quasi-TEM signal, which minimizes the signal distortion. Also, the structure acts as a large heat sink, which minimizes the operating temperature. As a result, the expected added noise by the proposed amplifier shall be minimal. © 2020 IEEE.
