Measurement of microwave and UHF signals is often done with sampling techniques. In this paper, the techniques and technology of sampling of electrical signals is reviewed from 1950 to the present. It includes both references to the open literature, as well as an extensive review of relevant patents. It also provides an overview of sampling applications and the use of computer technology to compensate and correct for errors in the sampling process.

This paper reports a novel MMIC sampler based on NLTL technology which has been designed using the Philips ED02AH process. The sampling MMIC can be used to measure waveforms in the (3-+34) GHz bandwidth. A tapered microstrip based NLTL pulse generator has been combined with a diode-resistor bridge to minimize on GaAs real estate compared to CPW methodology. The advantage of the designed sampling MMIC is wide bandwidth, compressed size and consequently lower cost. The sampling MMIC finds application in sampling oscilloscopes and Time Domain Reflectometers (TDRs). A CPW based NLTL shock wave generator has also been designedfor comparison based on bonding several MMIC NLTL samples together.
