Single Channel RF Rotary Joint DC-18GHz 50Ω SMA-F Interface 300RPM Stainless Steel for Radar Rotating Antenna
Product Overview
Our single-channel RF rotary joint (slip ring) is engineered to deliver uninterrupted, high-frequency signal transmission between stationary and rotating platforms. With a compact flange design and robust stainless steel housing, it ensures reliable performance in demanding dynamic environments.
Key Features & Advantages
- Wide Frequency & High Power: Covers DC-18GHz with 50Ω impedance. Handles high average power: 100W (DC-2GHz), 50W (2-8GHz), 25W (8-15GHz), and 20W (15-18GHz).
- Superior RF Performance: Ultra-low VSWR (Max 1.25) and low insertion loss (Max 0.3dB) guarantee signal integrity and minimal reflection.
- Durable & Compact: 25.40mm flange diameter, lightweight yet sturdy stainless steel construction. Rated IP41 for basic dust and moisture protection.
- High-Speed & Long Life: Supports rotational speeds up to 300RPM with a minimum operating life of 10 million revolutions.
- Harsh Environment Ready: Operates reliably in temperatures from -40℃ to +80℃. Complies with GJB150 standards for damp heat, vibration, and shock resistance.
- Easy Integration: Equipped with standard SMA-F interfaces for quick connection.
