CAE Interfaces with HP Automatic Network Analyzers

Abstract

Recent enhancements in microwave simulator programs, such as EEsof's Touchstone, now permit the designer to use measured data to refine theoretical models. These models can now reflect manufacturing variables and non-ideal elements which will greatly enhance the predictability of future designs. The measured data is supplied through direct interaction with the HP 8510 or 3577 automatic network analyzers. Many exciting applications result -- active device characterization, de-embedding and component measurement for use in upgrading model parasitics to reflect the real world, to name a few. This paper presents the design of a 2 to 6 Ghz four-stage feedback amplifier to illustrate the power of the microwave simulator/automatic network analyzer interface.
