Description
Yujie Zhi and co-authors build the front end of a wireless link that spans 67 to 110 gigahertz, in a 2026 paper. Such millimeter waves are a hunting ground for 6G speed. Their design starts with a waveguide diplexer that splits bands with little loss, then adds transitions that filter as they convert between waveguide and circuit board.
Built and measured, the parts held loss under 1.5 decibels and crushed out-of-band signals by over fifty decibels. The full front end, with amplifiers and oscillator, kept harmonics sixty decibels down. Clean, wide, and compact is exactly what future pocket radios will need.
