ETL Systems Swift SWF-G2S-S6-118 2×1 S-Band Latching RF Redundancy Switch

ETL Systems Swift SWF-G2S-S6-118 2×1 S-Band Latching RF Redundancy Switch

The ETL Systems Swift SWF-G2S-S6-118 provides automatic RF redundancy switching over 500–3150 MHz using a latching electromechanical relay. RF detection at both inputs supports switching based on signal-level difference or active-path level. After switching, the module maintains the selected path when the original signal recovers, reducing unnecessary switching operations. Its hot-swappable design integrates with compatible StingRay GENUS 2U or outdoor chassis.

Key Features

• Automatic switching by input-level comparison or active-path level

• Latching operation retains the new path after the original signal recovers

• Manual path selection through local or remote controls

• Hot-swappable, field-replaceable module

• Low insertion loss with 50 dB minimum path isolation

Requires a compatible GENUS chassis. Outdoor operation requires the appropriate protective outdoor chassis.
