On the Design of Reconfigurable Wideband Ridge Gap Waveguide Amplifier Modules

The near-to-launch 5G standard for wireless communications did not seal the ultimate use the mm-wave bands. As a result, the future 6G standard is expected to proceed in more efficient utilization of these bands. One of the most critical elements in the RF link is the amplifier, especially when the attenuation of the channel is relatively high which is the case for the mm-wave bands. In this work, a reconfigurable design of a wideband amplifier is presented to operate in the band 34 GHz to 38 GHz. The line parameters are investigated to study the tune-ability of this configuration. In particular, changing the parasitic loading by varying lines width can achieve a matching level beyond 15 dB over partial band operations based on the configuration. The availability of such a reconfigurable module will pave the way for efficient 6G development.
