Abstract :
A 50 GHZ sampler whose performance is a result of the addition of a small GaAs nonlinear transmission line is described. The compact hybrid microcircuit also features a step recovery diode (SRD), a microstrip-to-slotline balun and a GaAs integrated sampling bridge to form a complete sampling subsystem. The conversion efficiency of the shockline-enhanced sampler was improved over the full measured frequency range of 2-60 GHz when compared to the response of the sampler that did not use a shockline.<>
