Overview
The Siretta ALPHA22/3M/SMAM/SMAM/SMAM/S/S/26 is a passive indoor cellular and GNSS combo antenna. It operates across a frequency range of 698 MHz to 2.7 GHz with a linear gain of 2 dBi. The unit features an adhesive or chassis mount configuration and includes three 3-meter RG174 cables terminating in SMA male connectors. Designed for multi-protocol support including GSM, UMTS, LTE, WiFi, GPS, GLONASS, and Galileo, it ensures comprehensive connectivity for IoT and M2M applications requiring simultaneous cellular and satellite positioning.
Feature Summary
- Combines cellular reception with GNSS positioning capabilities in a single compact puck design
- Supports multiple wireless protocols including 2G, 3G, 4G, WiFi, and global navigation satellite systems
- Features flexible mounting options via adhesive backing or chassis screw installation
- Includes pre-attached 3-meter low-loss coaxial cables for convenient integration
Applications
- Industrial IoT gateways requiring integrated location tracking
- M2M communication modules for asset tracking
- Smart metering and utility automation devices
- Vehicle telematics and fleet management systems
- Home automation hubs with cellular backhaul
Procurement Notes
Verify the specific connector polarity and cable length requirements against your system design before ordering. Confirm that the adhesive mounting surface is compatible with your enclosure material. Ensure that the SMA male connectors align with your device's female ports. Check regulatory compliance documentation for target markets. Validate frequency coverage matches all supported network bands in your deployment region.
Selection Notes
Select this model when both cellular data and precise GNSS positioning are required within a single component footprint. The 2 dBi gain is suitable for indoor environments with moderate signal attenuation. Consider the 3-meter cable length for routing flexibility away from noisy electronics. This part is ideal for space-constrained designs where separate antennas would exceed available volume.
Part Context
This component belongs to the Siretta ALPHA series, which specializes in multi-band cellular and GNSS combo antennas. The ALPHA series is engineered for robust performance in industrial and commercial IoT applications. It integrates seamlessly with modern embedded systems requiring reliable connectivity and location services without increasing board complexity.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific configuration. Alternative solutions may require separate cellular and GNSS antennas if combined functionality is not strictly necessary. Verify compatibility with existing RF front-end components when considering different manufacturers.
