An improved two-tier L-L method for characterizing symmetrical microwave test fixtures is introduced in this paper. The improved two-tier L-L method is implemented with two uniform transmission lines having the same characteristic impedance and propa

The classical method for extracting the intrinsic elements of the small signal equivalent circuit of the FET is based on the knowledge of intrinsic Y ij -parameters. It requires finding the frequency range where the value of each intrinsic element is

In this paper, the parasitic and intrinsic elements of the coplanar PHEMTs are determined from S-parameter measurements corrected using the classical LRM calibration technique and the improved LRM with a reference line of arbitrary length. For the fi

A novel procedure to characterize coaxial line-stretcher phase shifter based on the two-line method is presented in this work. Intrinsic losses and differential phase shift are determined using S-parameters data measured with an uncalibrated vector n

In this paper a straightforward method to determine the parasitic gate resistance (R g ) of GaN FET is introduced. The method uses a simple linear regression to directly determine the value of R g without prior knowledge of the Schottky diode resista

By using an indirect method for determining the characteristic impedance of uniform transmission lines embedded in coaxial connectors, a novel two tier L-L de-embedding method is presented. The proposed de-embedding method is suitable for S parameter

In this paper we present a new method for calculating the characteristic impedance of the transmission lines embedded in identical, symmetrical and reciprocal transitions. For calculating the matrix elements of the transitions as well as the characte
