The propagation of terahertz-bandwidth electrical pulses with low distortion has been demonstrated using an ultra-broadband coplanar waveguide fabricated on durable 1.4-/spl mu/m-thick membrane substrates. This CPW was characterized using an in situ test-signal pulse generator and an electro-optic sampling technique, which also individually resolved the propagation of even and odd mode waveforms in the time domain. The attenuation and mode-propagation characteristics for this CPW and a CPW on a GaAs substrate are compared.<>
