(b) for other types of RF connectors, specific product specific analysis, if both have the potential of broadband structure, but also the objective needs of some measures of spread spectrum, generally speaking can be achieved Spread Spectrum purpose.
(c)for the spread spectrum connection, the interface mechanical compatibility, can be inserted with each other. When mixed with the electrical performance is not necessarily such as spread spectrum as well.
(d) for 18 GHz applications, select the type TNC is a good compromise between the ultra-compact SMA and larger N-type connector, it can be applied to medium-size cable, such as SYV50-2 SYV50-3, RG-142 RG141 and RG250 good RF performance, the TNC type connector can be used in the power level higher than the SMA connectors, TNC series of N-type connector size is small and light weight, they are more likely installed in the device requires intensive package.
(e) adjust the insulating support in the axial location and design of structural connectors, sometimes can reach to reduce the relative permittivity of the insulating support, but also to achieve the purpose of spread-spectrum, but also one of the lower connector VSWR measures deviation, due to calculation error and mechanical processing, the application should be combined with tests to determine the location and structure of the insulating support.
