141. Electrical characterization methods for high-speed interconnections
Published: 8/1/1996
Authors: Roger Marks, Dylan F Williams

142. Thermal Noise in Lossy Waveguides
Published: 7/1/1996
Author: Dylan F Williams
Abstract: This work rigorously treats thermal electromagnetic noise in lossy waveguides and develops explicit modal equivalent­ circuit representations for the noise generated by arbitrary passive networks embedded in them. The results show that the formulatio ...

143. On-Wafer Measurement at Millimeter Wave Frequencies
Published: 6/1/1996
Authors: Dylan F Williams, J. M Belquin, G. Dambrine, R. Fenton
Abstract: We investigate millimeter wave on-wafer calibration and measurement in coplanar waveguide and demonstrate the applicability of the multiline thru-reflect-line calibration and good measurement repeatability between laboratories. We also investigate ca ...

144. Line-Reflect-Match Calibrations with Nonideal Microstrip Standards
Published: 12/1/1995
Authors: Dylan F Williams, J. B. Schappacher
Abstract: We apply a previously developed Line-Reflect-Match (LRM) calibration that compensates for the nonideal electrical behavior of the match standard to microstrip transmission lines and investigate impedance definitions, standard parasitics, and calibrat ...

145. Coaxial Line-Reflect-Match Calibration
Published: 10/1/1995
Authors: Jeffrey A Jargon, Roger Marks, Dylan F Williams
Abstract: We describe a coaxial line-reflect-match calibration that corrects for imperfections in the load used as a match standard. The method provides a practical means of obtaining accurate, wideband calibrations with compact coaxial standard sets. When our ...

146. Fiber Coating Diameter: Toward a Glass Artifact Standard
Published: 9/1/1995
Authors: Dylan F Williams, M. Young, L. A. Tietz

147. Comments on "Conversions Between S, Z, Y, h, ABCD, and T Parameters which are Valid for Complex Source and Load Impedances"
Published: 4/1/1995
Authors: Roger Marks, Dylan F Williams
Abstract: In his recent paper, Frickey presents formulas for conversions between various network matrices. Four of these matrices (Z, Y, h, and ABCD) relate voltages and currents at the ports: the other two (S and T) relate wave quantities. These relationships ...

148. LRM Probe-Tip Calibrations Using Nonideal Standards
Published: 2/1/1995
Authors: Dylan F Williams, Roger Marks
Abstract: The line-reflect-match calibration is enhanced to accommodate imperfect match standards and lossy lines typical of monolithic microwave integrated circuits. We characterize the match and line standards using an additional line standard of moderate le ...

149. Compensation for Substrate Permittivity in Probe-Tip Calibration
Published: 12/1/1994
Authors: Dylan F Williams, Roger Marks
Abstract: We demonstrate a method of compensation for the effect of substrate permittivity on coplanar waveguide probe-tip scattering parameter calibrations, modeling the effect as a capacitance at the probe tip. Comparison to on-wafer multiline TRL calibratio ...

150. UWBain Network Analysis Using the Multiline TRL Calibration
Published: 12/1/1994
Authors: Roger Marks, L. A. Hayden, Jeffrey A Jargon, Dylan F Williams
