RF Performance of a 600 - 720 GHz Sideband-Separating Mixer with All-Copper Micromachined Waveguide Mixer Block

摘要

Here we report on the RF performance of a 2SB mixer (600-720 GHz) fabricated in a new method that combines traditional micromachining with waveguide components fabricated by photolithography and electroplating. The latter allows reaching, in a reproducible way, the stringent accuracies necessary for the critical RF components at these high frequencies.
