Characterization of transmission line based on advanced SOLTcalibration: Review

Abstract

Validation of analog IP's at high frequency is performed on a test board. For proper validation of IP's, it is very necessary to characterize the transmission line in such a manner that how much amount of signal is received at the destination & how much amount of losses introduce the transmission line. This paper proposed, Fixture free characterization of transmission line mounted on test board, based on advanced SOLT calibration performed on test dummy structure (ISS).Extraction of RLGC parameters, attenuation constant and phase constant of transmission line in very simple manner. Advanced probes technology minimizes insertion and return losses at high frequency which introduce by the adopters. Fixture free characterization minimizes phase delays produced by the adopters.
