In response to requests by U.S. industry and members of the International Electrotechnical Commision, the National Institute of Standards and Technology initiated a passive intermodualtion measurement comparison for the U.S. wireless industry. The goal of
Through its technical laboratory research programs, the Electronics and Electrical Engineering Laboratory (EEEL) supports the U.S. electronics industry, its suppliers, and its customers by providing measurement technology needed to maintain and improve
We use a general description of transmission lines to develop analytic descriptions for offset OSLT (Open-Short-Load-Thru) standards used to calibrate vector network analyzers.

We use SPICE simulations to determine a response function of a two-diode 20-GHz sampling circuit. We explore the validity of the SPICE simulations in a variety of operational conditions and examine differences between the actual response of an impedance
The NIST Noise Project has developed the theoretical formalism and experimental methods for performing accurate noise-temperature measurements on wafer. This report summarizes the theoretical formulation and describes the design, methods, and results of

In this paper, we review the system design, antenna structures, and optoelectronic components that can be used to accurately measure electromagnetic (EM) fields at frequencies up to 100 GHz, in support of the technologies of telecommunications, materials
A new spatial correlation function is derived for the axial electric field and is compared with the previously known spatial correlation function for the total electric field. The new correlation function is used to determine the average power received by
This paper presents a full-wave analysis of the split-cylinder resonator. We outline a model where the fringing fields are rigorously accounted for and the resonance condition is derived. using this model, a method for nondestructively measuring the
Antenna and electric field probe calibration requires precise positioning and movement throughout a known RF field Measurements are usually made in an anechoic chamber. A robotic six axis antenna positioner was needed that would work in this environment at
