Progress Toward MMIC On-Wafer Standards

November 1, 1990
Author(s)
Dylan F. Williams, Roger Marks, K. R. Phillips, T. Miers
A prototype standard set in coplanar waveguide suitable for the calibration of wafer probe stations has been developed through a cooperative effort between the National Institute of Standards and Technology and a MIMIC Phase 3 team. The coplanar standard

The Interpretation and Use of S-Parameters in Lossy Lines

November 1, 1990
Author(s)
Dylan F. Williams, Roger Marks
Although a fundamental parameter of transmission lines, the characteristic impedance is difficult to measure accurately. We suggest a method by which it may be easily determined from a measurement of the propagation constant. The method is based on a

The NIST Working Form for STEP

November 1, 1990
Author(s)
Steve Clark
The Product Data Exchange Specification (PDES) is an emerging standard for the exchange of product information among various manufacturing applications. The natural exchange medium for PDES product models is the STEP physical file format. The National PDES

Growth of YBa2Cu3O7 thin films on MgO: the effect of substrate preparation

October 30, 1990
Author(s)
Stephen E. Russek, Brian H. Moeckly, D. K. Lathrop, R A. Buhrman, Jian Li, J. W. Mayer
We discuss the results of a study on growth by laser ablation of YBa2CuO7 thin films on polycrystalline and annealed vicinal (001) MgO substrates. In both instances the films were found to grow predominantly with c axis normal to the plane of the substrate

Heat Release Rate: The Single Most Important Variable in Fire Hazard

October 20, 1990
Author(s)
Vyto Babrauskas, Richard Peacock
Heat release rate measurements are sometimes seen by manufacturers and product users as just another piece of data to gather. It is the purpose of this paper to explain why heat release rate is in fact, the single most important variable in characterizing

NIST Network Common Memory User Manual

October 1, 1990
Author(s)
Don E. Libes
This manual describes how to use the NIST Network Common Memory Systems (CMS), version 7. The CMS provides a common memory that may be shared among processes distributed across a local area network. Unlike other shared memory systems, CMS accesses
