Introduction to JINPAT Radar Slip Ring Technology

Introduction to JINPAT Radar Slip Ring Technology

Radar can be found in airports, high-rise buildings, and various civilian ships. In addition to active phased array radars or other types of fixed array radars, which have a fixed surface, all rotating radars require a slip ring. The radar slip ring is installed on the rotating base of the antenna and is used to transmit RF signals and electrical energy when the antenna rotates infinitely. This characteristic makes most radar slip rings integrated products of RF slip rings and electrical slip rings.

In some special radars, even pneumatic and liquid channels need to be integrated to provide cooling for components such as the transmitter on the radar panel. As a professional and experienced supplier of rotating conductive solutions, JINPAT has developed various types of integrated slip rings and high-frequency signal slip rings with independent intellectual property rights. The JINPAT high-frequency slip ring has reached the world's advanced level in terms of electrical and mechanical performance such as VSWR, insertion loss, maximum speed, and service life. The self-research capability of high-frequency slip rings determines that JINPAT will have a place in the radar slip ring market.

In terms of product structure, JINPAT radar slip rings generally have three types: pancake type, through-hole type, and columnar type. The internal structure of the slip rings of the latter two types is no different, so they are classified into the JINPAT LPT series when named. First, let's take a look at the pancake LPK series radar slip rings. Due to their structural advantages, pancake slip rings are generally installed in narrow axial spaces on vehicle-mounted or airborne platforms. The pancake radar slip ring is mainly a one-piece structure product, and its body generally has a certain size of through-hole for installing high-frequency slip rings. In addition to pancake slip rings, hollow shaft slip rings with through-holes also use the same high-frequency slip ring integration method.

Columnar radar slip rings, like those large through-hole radar slip rings, are generally medium to large-sized products. They do not integrate small components such as high-frequency slip rings, but use the traditional conductive slip ring solution by directly connecting the coaxial cable inside the slip ring to solve the problem of high-frequency signal transmission. The development difficulty of through-hole radar slip rings lies in the consistency control of RF signals among the channels, the delay consistency, and the isolation between channels. Moreover, the larger the aperture, the higher the development difficulty. Due to long-term investment in this field, JINPAT technical strength in the field of large through-hole radar slip rings is also at the forefront of international slip ring manufacturers.
