同轴连接器频率范围 Coaxial Connector Frequency Ranges
同轴连接器类型coaxial connector types:
The coaxial connector types mainly used in upper microwave and millimeter-wave frequency range are summarized in the table below. K connectors and V connectors are the trademarks of Anritsu. Their equivalents are 2.92 mm and 1.85 mm connectors, respectively. SMA is the trademark of Omni- spectrum, now, Tyco Electronics.
The inner diameter of the outer conductor “D”, outer diameter of the inner conductor “d” an dielectric constant of the connectors are used to name the connector types, for example, 2.92 mm is the outer connector’s inner diameter. In addition, one can also see that the TEM mode operating frequency range of these connectors is extended beyond what the industry normally uses. For example, the K connector can be operated up to 45 GHz and V connector can be extended to 72 GHz versus specified 67 GHz, respectively, without abrupt performance degradations.
同轴连接器主要用于超高微波和毫米波频率范围，其类型总结如下表。
*备注：
Anritsu安立公司的K和V连接器对应分别为2.92毫米和1.85毫米连接器。
SMA是Omni- spectrum即现在泰科电子的标准。
外导体的内径“d”、内导体的外径“d”、连接器的介电常数用来命名连接器的类型，例如，2.92 mm是外连接器的内径。此外，人们还可以看到，这些连接器在使用上通常可以超过TEM模式电磁波工作频率范围。
例如，不影响性能的前提下，K连接器可用于高达45 GHz；V连接器可以扩展到72 GHz（而标称67 GHz）。
