Design of Bias Tees for a Pulsed-bias, Pulsed-RF Test System Using Accurate Component Models

In this article, a design of custom bias tees to be used in a pulsed-bias, pulsed-RF measurement system is described. The bias tee design is such that the DC path allows bias pulses to pass through to the device unchanged, while still allowing RF measu...
