The collector ring, also known as the slip ring, is an indispensable component of the rotary antenna system and the communication equipment in motion. Except for some low-end applications that have a short scanning area, most antenna slip rings must include an RF signal module. This RF module has different names depending on the industry. As a professional manufacturer of slip rings, JINPAT Electronics calls such a module a high-frequency rotary joint or RF rotary joint. This rotary joint can support max. 4 channels. The frequency range is the same as that of the antenna and the communication equipment in motion.

The high-frequency rotary joint or RF slip ring is usually combined with a through-hole slip ring. The high-frequency rotary joint is built into the through-hole. Most of JINPAT’s hybrid RF slip rings use this design. As for those that can’t be satisfied with the solid shaft slip ring, the intermediate frequency through-hole slip ring can help.

JINPAT LPHF-02A RF Slip Ring The combination is a completely new hybrid electric slip ring that works on radio frequencies. Generally speaking, the RF slip ring is a standard product. There is no need to adjust the signal transmission. Thus, it has a shorter production process. As for the through-hole RF slip rings, they are custom-made. Signal consistency, delay consistency, and isolation between circuits are all elements to consider. Some changes need to be made before mass production.

In short, JINPAT Electronics has good qualification to develop RF rotary joint stands and customized through-hole RF rotary joints. Take JINPAT Stand LPHF-02A RF rotary joint for example. It is a very mature model of RF slip ring. It is a popular sales model that receives positive feedback from customers. As for the through-hole RF slip ring, the through-hole diameter can reach 120mm max. keywords RF rotary joints High frequency rotary joints
