Specialized techniques and instruments for measuring performance at higher frequencies.
Logarithmic amplifiers provide an output voltage that is logarithmically scaled relative to the amplitude envelope of the input signal. Historically these have been used to provide logarithmic Y-axis scaling to spectrum analyzer displays, for example. This app note describes the basic block diagram and principles of operation of a log amplifier.
Converting a phase noise specification to jitter is often desirable for digital designers and others used to working in the time domain. This app note describes the principles of phase noise as well as deriving the conversion to jitter. A useful list of references is also included.
This connector identifier guide features schematic drawings of over 50 different connector types in each gender. The guide also features a chart comparing the maximum frequency capability of each type. A small glossary of RF terms is also included.
A brief overview of power meter technologies as well as links to other valuable resources on the subject. A survey of power meter vendors is also included.
This application note provides and in-depth analysis of the performance of connections using mixed connector types among SMA, 3.5-mm, and 2.92-mm varieties. These connectors are all designed to work together mechanically, but have some differences electrically.
This application note discusses the use of SMA connectors in the lab, along with their performance when mated to APC 3.5mm connectors.

Coaxial cable connectors are a fundamental component for interfacing with RF devices up to hundreds of gigahertz. The frequency handling capability of coaxial connectors is based upon the dimensions of the inner and outer conductors, as well as the quality of precision in which the parts of the coaxial connector are constructed. Coaxial connectors are generally designed with either 50 or 75 ohms of impedance. The impedance of the coaxial connector is dictated by the dielectric material between the inner and outer conductors and their ratio.
