RF rotary joints transmit RF signals during rotation using sliding gold-plated contacts (12-24 channels) or capacitive coupling, maintaining <0.5dB insertion loss from DC-60GHz, enabling 360° movement in radar/communication systems without signal degradation. Basic Working Principle An RF rotary joint, often called a slip ring, is a precision electromechanical device that enables the continuous transmission of […]

To select the right coaxial attenuator, match its frequency range (e.g., 50MHz–6GHz) to your system’s operating band. Choose attenuation (3dB/10dB) based on signal level needs; ensure power handling (≥10W CW) exceeds peak input. Prioritize low VSWR (≤1.5) for minimal reflection, and verify with a network analyzer. Opt for corrosion-resistant materials (brass/stainless steel) for durability. Understand
