Integrated Terahertz Transmit / Receive Modules

摘要

We report on research and development ofmillimeter-wave components used in prototype 600 GHztransmit and receive systems. These systems offer state-ofthe-art performance in terms of noise, power, ease of useand mechanical and electrical robustness. The transmitterscomprise high-power frequency multiplier chains driven bycommercial power amplifiers in the 18-45 GHz range andlower frequency fundamental oscillators. The receiverscomprise a subharmonic mixer and an LO multiplier chain.All of the components are based on planar GaAs Schottkydiodes in fixed-tuned broadband embedding structures.These designs are scalable to any frequency in the bandfrom 100 GHz through 1 THz and we are exploring thechallenges of scaling to the 1-5 THz band.
