Overview
The Siretta ALPHA3A/3M/SMAM/S/S/26 is a passive cellular antenna designed for indoor applications. It operates across multiple frequency bands, specifically covering 824 MHz to 894 MHz, 1.71 GHz to 2.17 GHz, and 2.4 GHz to 2.5 GHz. The unit features a 3-meter cable length terminated with an SMA male connector. This component supports various cellular protocols including GSM, UMTS, DCS, PCS, GPRS, WCDMA, LTE, NB-IoT, and ISM sub-GHz standards.
Feature Summary
- Supports multi-band cellular communication protocols including GSM, UMTS, LTE, and NB-IoT
- Includes a 3-meter integrated cable for flexible installation positioning
- Utilizes an SMA male connector interface for standard RF equipment compatibility
Applications
- Indoor cellular signal distribution systems
- IoT device connectivity modules supporting LTE and NB-IoT
- Wireless infrastructure requiring multi-band GSM and UMTS coverage
Procurement Notes
Verify the specific SMA male connector polarity and impedance matching requirements against your host device specifications before integration. Confirm that the 3-meter cable length aligns with your system layout constraints. Ensure the operating frequency range fully encompasses your target network bands to maintain optimal signal integrity and protocol compliance.
Selection Notes
Select this model when indoor multi-band cellular coverage is required without external mounting options. The fixed 3-meter cable length offers a balance between reach and manageability for internal routing. Consider the SMA male interface compatibility with your existing RF connectors and ensure the passive design meets your power handling needs.
Part Context
This component belongs to the ALPHA series of antennas manufactured by Siretta Ltd. The series focuses on providing reliable connectivity solutions for various wireless standards. The specific part number indicates the inclusion of a 3-meter cable and SMA male termination, distinguishing it from other variants in the lineup that may feature different lengths or connector types.
Replacement Considerations
Direct substitutes within the ALPHA series may vary by cable length or connector type. Verify functional equivalence regarding supported frequency bands and protocol compatibility. Ensure any replacement maintains the same SMA male interface and 3-meter cable specification to preserve mechanical fit and electrical performance.
