各种射频接头指南C ONNECTOR APPLICATION GUIDE RF RF Connector Interface Styles and Applications Coaxial connectors are commonly referred to as "RF" connectors, although most connector styles can be used at microwave frequencies. The term "RF (Radio Frequency) generally refers to frequencies in the MHz range, while microwave frequencies are greater than 1 GHz. Coaxial connectors are grouped into categories based on their physical size and cable compatibility. The coaxial connector categories are listed below: Standard Miniature Sub-Miniature Micro-Miniature In general, these groupings represent the development of coaxial connector design from the 1930’s to the 1980’s. In the early days, the only coaxial cables available were much larger in diameter than most common coaxial cables used today. Therefore, t……
