APAMS-131 RF Antenna Equivalent & Substitute Parts

Part Overview

The APAMS-131 is a dual-band RF whip antenna manufactured by Abracon LLC, designed for 900MHz and 1.8GHz frequency bands with 3dBi gain and SMA Male base mount termination. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system design and procurement. The antenna operates across 890MHz–960MHz and 1.71GHz–1.88GHz frequency ranges, suitable for applications requiring compact, straight whip antenna configurations with standard SMA connectors.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the APAMS-131 are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Termination type: SMA Male (required for connector compatibility)
• Antenna configuration: Whip, Straight (physical form factor)
• Frequency coverage: Must encompass or overlap the 900MHz and 1.8GHz bands
• Mounting capability: Base mount or equivalent fixed installation method
• Compliance: ROHS3 and REACH compliance maintained

Substitute Parts Identified:

1. GA.107.201111 (Taoglas Limited) – Wide-band cellular antenna covering 800MHz–2.2GHz with 5dBi gain, SMA Male base mount. Frequency range encompasses both 900MHz and 1.8GHz bands with higher gain performance.

2. MB.TG30.A.305111 (Taoglas Limited) – Multi-band antenna covering 600MHz–6GHz with magnetic mounting and 3m cable. Supports 8 frequency bands including 892MHz and 1.955GHz, with variable gain across bands. Magnetic mount provides alternative installation flexibility.

Parameter Comparison

Engineering Selection Recommendations

GA.107.201111 Selection Criteria:

• Recommended for direct replacement in applications requiring consistent base mount installation
• Active product status ensures long-term availability and supply chain stability
• Frequency range 800MHz–2.2GHz provides full coverage of APAMS-131 operating bands with margin
• Higher gain (5dBi vs. 3dBi) improves link budget performance
• Identical VSWR specification (2) maintains impedance matching characteristics
• Packaging in Bag format suitable for standard component handling

MB.TG30.A.305111 Selection Criteria:

• Applicable for applications requiring multi-band operation beyond 900MHz and 1.8GHz
• Magnetic mounting provides installation flexibility where base mount is not feasible
• Integrated 3m cable eliminates separate cable procurement
• IP67 ingress protection rating extends environmental operating range
• Frequency coverage 600MHz–6GHz supports CDMA, GPRS, GPS, HSDPA, LTE, UMTS, WCDMA, and Wi-Fi applications
• Larger physical height (196.10mm) requires space verification in mechanical design

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original APAMS-131 specification.

Frequently Asked Questions (FAQ)

Q: Can GA.107.201111 directly replace APAMS-131 in existing designs? A: Yes. Both parts feature SMA Male termination, whip straight antenna configuration, base mount installation, and VSWR of 2. The GA.107.201111 covers the full frequency range of APAMS-131 (890MHz–960MHz and 1.71GHz–1.88GHz) within its 800MHz–2.2GHz operating range. Physical height difference (116mm vs. 109mm) requires mechanical clearance verification.

Q: What is the primary difference between GA.107.201111 and MB.TG30.A.305111? A: GA.107.201111 is a single-band cellular antenna with base mount, optimized for 900MHz and 1.8GHz coverage. MB.TG30.A.305111 is a multi-band antenna with magnetic mount supporting 8 frequency bands across 600MHz–6GHz. Selection depends on frequency requirements and mounting constraints.

Q: Does MB.TG30.A.305111 require additional installation components? A: MB.TG30.A.305111 uses magnetic mounting, which requires a ferrous metal surface for attachment. It includes a 3m integrated cable. Base mount applications may require adapter evaluation or mechanical redesign.

Q: Are all substitute parts RoHS3 compliant? A: Yes. APAMS-131, GA.107.201111, and MB.TG30.A.305111 are all ROHS3 compliant with REACH unaffected status, meeting current regulatory requirements.

Q: What is the impact of gain difference between APAMS-131 (3dBi) and GA.107.201111 (5dBi)? A: The 2dBi gain increase in GA.107.201111 improves received signal strength and transmission efficiency. This is beneficial for link budget performance but does not affect connector compatibility or frequency band operation.

Q: Can packaging format affect component selection? A: Packaging format (Bag vs. Box) affects handling, storage, and logistics but does not impact electrical or mechanical performance. GA.107.201111 is supplied in Bag packaging; MB.TG30.A.305111 is supplied in Box packaging.
