What factors should be considered when choosing an RF connector
RF connector is a kind of connection device that can transmit RF signals with small loss and reflection in RF transmission system and provide fast and repeated connection. It is mainly composed of contacts, insulators, shells and accessories. The RF connector should be selected with reliable contact, good conductive insulation performance, sufficient mechanical strength, and the number of plug-ins to meet the relevant international and domestic standards. At the same time, there are many factors that determine the connector series and style, of which the mating cable and the use of frequency range are the main factors. In engineering practice, make the connector diameter and cable diameter as close as possible to minimize reflections. The greater the difference between cable diameter and connector diameter, the worse the performance. Reflections generally increase as a function of frequency, and generally smaller connectors perform well at higher frequencies. For very high frequencies (above 26GHz), sophisticated air media connectors are required.

Switching Power Supply Control Loop Stability Test Using Frequency Response Analyzer (FRA)
Today, the demand for high-performance power systems is increasing, from applications in high-energy and efficient aerospace and automotive systems to applications in highly efficient battery systems with very low power consumption (such as consumer and medical electronics). Because of this demand in the market, it is particularly important to optimize the design of energy conversion to achieve the goal of high cost performance.
