APAMPS-105 Equivalent & Substitute Parts

Part Overview

The APAMPS-105 is a multi-band RF antenna module manufactured by Abracon LLC, designed for cellular and navigation applications. This adhesive-mounted antenna operates across three frequency bands: 900MHz, 1.575GHz, and 1.8GHz, with coverage spanning 806MHz to 1.88GHz. The module features dual termination options (SMA Male and FME Female connectors), integrated LNA, and a 3-meter cable assembly. The product maintains Active status with full RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements necessitate alternative antenna configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the APAMPS-105 is determined by the following critical parameters:

Frequency Coverage: The substitute part must support the three primary frequency bands (900MHz, 1.575GHz, 1.8GHz) with equivalent or broader frequency range coverage to maintain functional compatibility in GPS and GSM applications.

Antenna Configuration: Both the main part and substitute must utilize adhesive mounting to ensure mechanical compatibility with existing PCB layouts and enclosure designs.

Termination Type: The substitute part must provide SMA Male connectors to maintain electrical interface compatibility with downstream RF circuitry.

Regulatory Compliance: Both parts must maintain RoHS3 compliance and equivalent moisture sensitivity ratings to satisfy manufacturing and environmental requirements.

Gain and VSWR Characteristics: The substitute part must operate within acceptable gain and VSWR ranges for the specified frequency bands to ensure equivalent RF performance.

The MA208.A.AB.001 from Taoglas Limited satisfies these substitution criteria through its support of all three primary frequency bands, adhesive mounting configuration, dual SMA Male termination, and equivalent RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the APAMPS-105 and MA208.A.AB.001 maintain Active product status with full RoHS3 compliance, ensuring long-term availability and regulatory alignment for production environments.

The MA208.A.AB.001 provides extended frequency band coverage (7 bands versus 3 bands) and includes integrated filtering in addition to LNA functionality. This configuration supports broader application scope including CDMA, DCS, LTE, PCS, and UMTS standards beyond the GPS and GSM focus of the APAMPS-105.

The APAMPS-105 features a more compact dual-termination design with both SMA Male and FME Female connectors, providing flexibility in RF interface options. The MA208.A.AB.001 utilizes dual SMA Male termination, requiring interface adaptation if FME Female connectivity is required in the target application.

Physical form factor differs between the two parts: the APAMPS-105 presents a module configuration at 15.80mm height, while the MA208.A.AB.001 employs a flat bar design at 9.00mm height. This dimensional difference may influence PCB layout and enclosure integration considerations.

Selection between these parts should be based on specific application requirements regarding frequency band support, connector type compatibility, and physical space constraints within the target system.

Frequently Asked Questions (FAQ)

Q: Can the MA208.A.AB.001 directly replace the APAMPS-105 in existing designs?

A: Direct replacement requires verification of three factors: (1) SMA Male connector compatibility with existing RF circuitry, as the MA208.A.AB.001 does not provide FME Female termination; (2) PCB layout accommodation of the reduced 9.00mm height profile; (3) confirmation that the extended frequency band coverage does not introduce unintended RF coupling or interference in the target application.

Q: What are the key differences in RF performance between these parts?

A: The APAMPS-105 specifies VSWR values of 1.5 and 2.0 across its three frequency bands. The MA208.A.AB.001 specifies VSWR values of 3.3, 3.6, and 2.2 across its seven frequency bands. Gain characteristics differ across the frequency spectrum, with the MA208.A.AB.001 providing higher gain at certain bands (4.6dBic) and lower gain at others (0.42dBi) compared to the APAMPS-105 range of -1dBi to 5dBic.

Q: Are both parts suitable for GPS and GSM applications?

A: Yes. Both parts support the 900MHz and 1.575GHz frequency bands required for GSM and GPS operation respectively. The MA208.A.AB.001 extends support to additional cellular standards (CDMA, DCS, LTE, PCS, UMTS) and frequency bands beyond the core GPS/GSM requirement.

Q: What is the significance of the integrated filter in the MA208.A.AB.001?

A: The MA208.A.AB.001 includes integrated filtering in addition to LNA amplification. This configuration provides additional RF selectivity and may reduce out-of-band interference compared to the APAMPS-105 LNA-only design. Filter characteristics are not specified in the provided parameters.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the APAMPS-105 and MA208.A.AB.001 maintain ROHS3 compliance. The APAMPS-105 is REACH Affected; the MA208.A.AB.001 is REACH Unaffected. Both parts carry identical ECCN classification (7A994) for export control purposes.

Q: What packaging considerations apply to these parts?

A: The APAMPS-105 is supplied in standard packaging. The MA208.A.AB.001 is supplied in Bag packaging. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control requirements during storage or handling.
