To understand the domestic price of high-frequency slip rings and what technical standards can be achieved, we must first understand the working principle of high-frequency slip rings. High frequency slip ring, also called high frequency rotary joint, includes coaxial rotary joint, waveguide rotary joint and coaxial/waveguide rotary joint, also called radio frequency slip ring.
The high-frequency slip ring is specially developed for the transmission of high-speed serial digital signals or analog signals such as high-definition signals, radio frequency signals, and microwave signals. This series of products supports single-channel or multi-channel high-frequency signal transmission alone, and also supports mixed transmission of high-frequency signals, control signals, communication signals, power and fluid media, that is, combined slip rings.
High-frequency slip rings are mainly used for air traffic control radars, radar antennas, rotating batteries, military radar systems, airborne mobile communications, high-definition network video surveillance systems, medical engineering equipment, electronic warfare systems, missile defense systems, and multi-axis three-dimensional space simulation High-tech fields such as devices, satellite antennas, turntables, and navigation. It can be known from the application field of high-frequency slip ring that the price of domestic high-frequency slip ring is relatively high, ranging from several thousand to tens of thousands, depending on the specific application field and design requirements of high-frequency slip ring. There are few professional slip ring manufacturers for slip rings.
Single channel, when the frequency is 0-3G, insertion loss <1.2, standing wave <1.6, small size; divided into single channel and multi-channel, the highest frequency of single channel can reach 50GHz; the frequency of dual channel can reach 18GHz; The frequency is up to 3GHz.
The high-frequency slip ring can be used in continuous rotating devices to transmit high-frequency signals and high-speed signals between fixed parts and rotating parts. The following technical advantages can be achieved:
1. It can transmit analog signals and high-speed digital with frequencies up to 500 MHz-50 GHz Signal, can mix and transmit 1-200 power/signal.
2. Compact structure, stable performance, good shielding effect, strong anti-interference ability, and easy to integrate into other equipment.
3. It can be coaxial, waveguide, coaxial/waveguide hybrid transmission.
4. Ultra-low insertion loss and voltage standing wave ratio, high-frequency rotary joints with through holes can be customized.
5. Wide operating temperature range, suitable for extreme environment applications, and high degree of shape customization.
