The RF rotary joint design adopts the principle of high-frequency signal skin effect and coaxial cable structure simulation, which is used to transmit high-speed data and analog signals in continuous rotating devices. This type of slip ring can be divided into single-channel and multi-channel. The analog signal above 30-500MHZ also supports high frequency signal and control signal 24V, communication, power supply, fluid mixed transmission medium.
As picture shows a single-channel high-frequency rotary joint customized by Yingzhi Technology for customers, with a maximum transmission rate of up to 40GHz. In order to ensure low damage and reliable transmission of RF rotary joints and high-frequency signals, we have key internal contact points in the RF rotary joint Imported high-elastic wear-resistant materials are used, and special electroplating is done on the surface.
Specially designed for radio frequency signal transmission, the highest frequency can reach 40GHz
Coaxial contact design makes the connector have an ultra-wide bandwidth and no cut-off frequency
Multi-contact structure, effectively reducing relative jitter
The overall size is small, the connector is plugged and used, and it is easy to install
