Short Description
This is a custom medium-frequency slip ring platform (commercial name: Ingiant Medium Frequency Slip-Ring) providing three independent 50Ω RF channels for 1–5.25 GHz. Standard configuration uses SMA-F connectors, supports 10 W average power per channel, low insertion loss (≤1.2 dB), isolation ≥50 dB and phase stability from ±2° to ±4°. Rated operating range: -40°C to +70°C; IP51; minimum life 5 million revolutions at up to 30 RPM.

Product Overview
The slip ring maintains RF integrity (insertion loss, VSWR, isolation, phase) over continuous 360° rotation, preventing cable twisting and enabling reliable rotating RF interfaces for antenna pedestals, radar, test benches and other rotating microwave systems.

Engineering Interpretation of Key Parameters

• Frequency range: Covers L‑band, S‑band and lower C‑band; platform can be engineered up to DC–18/26.5/40 GHz.
• Power rating: 10 W CW per channel in matched conditions; higher ratings available with thermal design adjustments.
• Impedance stability: Low VSWR and small variation through rotation indicate precision RF contact and mechanical tolerances.
• Amplitude stability: Low insertion loss and limited variation are critical for amplitude‑sensitive systems.
• Isolation: ≥50 dB reduces channel leakage and intermodulation in multi‑carrier setups.
• Phase stability: ±2°–±4° suitable for coherent systems (phased arrays, interferometry, SAR) requiring precision bearings and matched contact surfaces.
