GLA.02 GPS Chip RF Antenna Equivalent & Substitute Parts

Part Overview

The GLA.02 is a 1.575GHz GPS chip RF antenna designed for surface mount applications with a solder termination. This component is classified as obsolete, which necessitates identification of active equivalent parts to maintain design continuity and ensure supply chain availability. The GLA.02 delivers 3dBi gain with a 2 VSWR rating and is fully RoHS3 compliant for modern manufacturing environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GLA.02 is determined by the following critical parameters:

• Frequency (Center/Band): Must match 1.575GHz for GPS navigation compatibility
• Antenna Type: Must remain Chip configuration
• Mounting Type: Must be Surface Mount
• Termination: Must be Solder
• RF Family/Standard: Must support Navigation applications
• RoHS Status: Must maintain ROHS3 compliance

The GLA.01.A meets all substitution criteria as an active product from the same manufacturer with identical frequency, antenna type, mounting method, and termination. While gain and return loss specifications differ, these variations remain within acceptable parameters for GPS receiver applications.

Parameter Comparison

Engineering Selection Recommendations

The GLA.01.A is the direct active equivalent for the obsolete GLA.02. Both components maintain identical frequency operation at 1.575GHz, matching RF family standards for GPS navigation. Both are ROHS3 compliant and manufactured by Taoglas Limited, ensuring regulatory alignment and supply chain continuity.

The GLA.01.A offers a significant height reduction (0.020" versus 0.154"), which may provide design benefits for space-constrained applications. The gain differential of 0.5dBi (3dBi to 2.5dBi) and return loss variation (-31dB to -19dB) are within acceptable tolerances for GPS receiver performance. The GLA.01.A is available in Tape & Reel packaging, supporting automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the GLA.01.A directly replace the GLA.02 in existing designs?

A: Yes. Both components operate at 1.575GHz with identical antenna type, mounting method, and solder termination. The GLA.01.A is the active equivalent specified by the manufacturer for GLA.02 obsolescence management.

Q: What is the impact of the 0.5dBi gain difference?

A: The gain reduction from 3dBi to 2.5dBi represents a 0.5dB decrease in radiated power. This variation is within normal GPS receiver design margins and does not compromise navigation performance in standard applications.

Q: Does the height difference affect PCB layout?

A: Yes. The GLA.01.A height of 0.020" (0.50mm) is significantly lower than the GLA.02 at 0.154" (3.90mm). This reduction may allow for lower overall product profile or improved component density. Verify clearance requirements in your specific application.

Q: Are there packaging considerations for production?

A: The GLA.01.A is supplied in Tape & Reel (TR) format, which is standard for automated surface mount assembly. The GLA.02 packaging format is not specified in available data. Confirm tape specifications with your assembly partner if transitioning from bulk or alternative packaging.

Q: Do both parts meet current compliance requirements?

A: Yes. Both the GLA.02 and GLA.01.A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.
