Abstract
We have developed electronic circuits that generate and detect subpicosecond shock-waves. We have used these circuits with integrated antennas in a system capable of free space spectroscopy with greater than 10 dB signal to noise from 5 GHz to 1 THz. This system was used to characterize a submillimeter wave filter from 6.4 GHz to 1 THz. In particular, 250-375 GHz measurements are demonstrated with 2 dB accuracy over a 20 dB dynamic range.
