MauryMaury Microwave was featuring a comprehensive line of coaxial and waveguide VNA calibration kits, which consist of accurate, stable, and precise calibration standards for a broad range of VNA models. When properly used, these kits ensure a true evaluation of VNA performance. Maury kits offer a range of performance and cost options which provide users with choices that are both technically and economically suitable for a variety of intended application. They were also featuring calibration-grade metrology, precision, and lab interconnect solutions including cable assemblies, adapters and more. Maury Microwave's Stability™ series sets the standard for high-performance ruggedized microwave/RF cable assemblies. Designed specifically for phase-stable and amplitude-stable applications, Stability™ offers excellent measurement repeatability even after cable flexure. Maury was also featuring their various characterization systems such as device characterization for power amplifier design. The ideal form of the amplifier device data is a large signal model from which the performance can be analyzed for varying drive and impedance conditions, so complex or multi-stage circuits can be designed. A method of formulating a large signal model is to use a measurement-based behavioral approach, as with the X-Parameter model. This is based on measurements of X-parameters, which are a superset of S-parameters for nonlinear components, and are measured using a Non-linear Vector Network Analyzer. Maury supplies various systems to characterize and models all types of devices.

M/C MitronMini Circuits/Mitron highlighted its expansive selection of RF/microwave components, including its ZVBP line of bandpass filters, MNA line of monolithic amplifiers, as well as its range of MMICs.
