GPSANT1 RF Antenna Equivalent & Substitute Parts

Part Overview

The GPSANT1 is a 1.575GHz flat patch RF antenna manufactured by RF Solutions, designed for UHF applications within the 1.525GHz to 1.625GHz frequency range. This component features an SMA male termination and is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs.

The obsolete status of GPSANT1 requires engineers to evaluate substitute components that maintain electrical and mechanical compatibility while ensuring continued availability and compliance with current regulatory standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of GPSANT1 is determined by the following critical parameters:

Frequency Compatibility: The substitute must operate at or encompass the 1.575GHz center frequency. APAMPG-130 operates at 1.575GHz and 1.602GHz, with frequency ranges of 1.572GHz ~ 1.578GHz and 1.594GHz ~ 1.61GHz, providing coverage of the original 1.575GHz specification.

Termination Type: Both components utilize SMA male connectors, ensuring mechanical and electrical interface compatibility.

Frequency Group: Both components operate within the UHF band (1GHz ~ 2GHz), maintaining the same frequency classification.

Moisture Sensitivity: Both components are rated MSL 1 (Unlimited), indicating equivalent environmental tolerance.

The APAMPG-130 substitute differs in antenna type (dome versus flat patch) and includes dual-band capability for GLONASS and GPS applications, but maintains the core electrical parameters necessary for 1.575GHz operation.

Engineering Selection Recommendations

Product Status Consideration: GPSANT1 is classified as obsolete, while APAMPG-130 maintains active product status with current manufacturing support and availability.

Regulatory Compliance: APAMPG-130 is ROHS3 compliant and REACH affected, representing current regulatory alignment. GPSANT1 is RoHS non-compliant, reflecting its obsolete classification.

Electrical Performance: APAMPG-130 provides specified VSWR (1.5) and gain (30dB) parameters, enabling quantified performance assessment. GPSANT1 specifications for these parameters are not provided.

Frequency Coverage: APAMPG-130 encompasses the 1.575GHz center frequency of GPSANT1 within its dual-band structure, with the primary GPS band (1.572GHz ~ 1.578GHz) directly overlapping the original specification.

Mechanical Differences: APAMPG-130 features magnetic mounting and specified height dimensions (0.610" / 15.50mm), whereas GPSANT1 mounting specifications are not provided. System integration must account for the antenna type transition from flat patch to dome configuration.

Frequently Asked Questions (FAQ)

Q: Can APAMPG-130 directly replace GPSANT1 in existing designs?

A: APAMPG-130 maintains electrical compatibility at the 1.575GHz center frequency and uses identical SMA male termination. However, the antenna type differs (dome versus flat patch), requiring mechanical integration assessment. Physical mounting and form factor compatibility must be verified for specific applications.

Q: What is the significance of the dual-band capability in APAMPG-130?

A: APAMPG-130 operates at both 1.575GHz (GPS) and 1.602GHz (GLONASS), providing multi-constellation navigation support. Systems requiring only 1.575GHz operation will function with APAMPG-130, though the additional band capability is not utilized.

Q: How do the frequency ranges compare between these components?

A: GPSANT1 specifies a single continuous range of 1.525GHz ~ 1.625GHz. APAMPG-130 specifies two discrete ranges: 1.572GHz ~ 1.578GHz and 1.594GHz ~ 1.61GHz. The APAMPG-130 primary GPS band (1.572GHz ~ 1.578GHz) is narrower but encompasses the 1.575GHz center frequency.

Q: What are the compliance implications of switching from GPSANT1 to APAMPG-130?

A: APAMPG-130 is ROHS3 compliant and REACH affected, meeting current regulatory requirements. GPSANT1 is RoHS non-compliant. New designs and systems subject to RoHS or REACH regulations must use APAMPG-130 or equivalent compliant alternatives.

Q: Are there packaging differences between these components?

A: GPSANT1 packaging is not specified. APAMPG-130 is supplied in bulk packaging. Procurement and inventory management processes may require adjustment based on available packaging formats.

Q: What is the impact of the magnetic mounting feature on APAMPG-130?

A: APAMPG-130 includes magnetic mounting capability, enabling rapid installation and repositioning on ferromagnetic surfaces. GPSANT1 mounting specifications are not provided. System design must accommodate or account for this mounting method difference.
