Abstract :
A GaAs monolithic time-domain reflectometer (TDR) for millimeter-wave network analysis has been fabricated. The nonlinear transmission line (NLTL)-based TDR has two outputs from which the incident and reverse waves can be determined. The two channels show a 2.3-ps falltime, and hence a 150-GHz 3-dB TDR bandwidth. The reflection coefficient in the time domain obtained after a partial calibration clearly indicates a prominent reflection when the TDR is under open-circuitry load. With the use of network analysis calibration routines, corrected millimeter-wave vector measurements will be feasible with these devices
