DELTA22/X/SMAM/S/S/20

Overview

The Siretta DELTA22B/X/SMAM/S/S/20 is a direct-mount ISM band antenna designed for sub-GHz applications. It features an omnidirectional radiation pattern with a gain of 3 dBi, optimized for frequencies around 915 MHz. The unit utilizes a male SMA connector for interface compatibility and incorporates a direct installation mounting style. Constructed as a passive whip antenna, it measures 115 mm in length. The component complies with EU standards and RoHS directives, ensuring suitability for regulated electronic environments.

Feature Summary

• Omnidirectional radiation pattern ensures consistent signal coverage in all horizontal directions.
• Direct mounting configuration allows for secure attachment without additional brackets.
• Passive design operates within the ISM frequency bands without external power requirements.

Applications

• Sub-GHz wireless sensor networks
• Industrial telemetry systems
• Remote monitoring devices

Procurement Notes

Verify that the specific suffix 'DELTA22B' matches the required model variant, as ordering codes may differ slightly from generic family names. Confirm that the SMA male connector polarity aligns with the receiving equipment interface. Ensure the direct-mount mechanical form factor fits the intended enclosure or panel space constraints before finalizing the order.

Selection Notes

Select this component when a compact, low-profile solution is required for sub-GHz ISM band operations. The 3 dBi gain provides a balance between size and performance for short-range communication links. Consider the 115 mm physical length to ensure adequate clearance during installation. This model is suitable for designs prioritizing simple integration over high-gain directional performance.

Part Context

This antenna belongs to the Siretta DELTA series, which focuses on compact passive antennas for various wireless protocols. The DELTA22B variant specifically targets ISM band applications, distinguishing itself from cellular or WiFi models within the broader portfolio. It represents a standard solution for manufacturers needing reliable sub-GHz connectivity in constrained spaces.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users must verify electrical compatibility and mechanical fit when considering alternative components from other manufacturers.
