Electronic calibration unit for DC-8 GHz vector-network-analyzer measurements

Abstract

We present design and realization of a vector-network-analyzer (VNA) electronic-calibration unit operating from DC to 8 GHz. Calibration standards are implemented on a printed circuit board and are connected to the VNA ports through a set of micro-electro-mechanical-system (MEMS) switches. We verify our unit by comparing corrected measurements of verification items obtained after calibrating the VNA with our electronic unit and with mechanical devices. The results show a very good agreement.
