4GDPSM Equivalent & Substitute Parts Reference

Part Overview

The PCTEL 4GDPSM is a multi-band dome RF antenna designed for cellular and navigation applications. This component operates across three frequency bands (698MHz–960MHz, 1.575GHz–1.61GHz, 1.71GHz–2.7GHz) and integrates a 5-meter RG-174/U cable with SMA Male connector termination. The 4GDPSM is currently listed as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system integration and maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4GDPSM is determined by the following critical parameters:

• Antenna Type: Dome configuration required
• Frequency Coverage: Must support LTE cellular bands (698MHz–960MHz, 1.71GHz–2.7GHz) and GNSS/GPS bands (1.575GHz–1.61GHz)
• Termination: SMA Male connector
• Cable Assembly: 5-meter RG-174/U cable
• Mechanical Compatibility: Maximum height 1.575" (40.00mm)
• Environmental Rating: IP67 ingress protection
• Compliance: ROHS3 certification

The PCTEL 710682 qualifies as a substitute based on matching antenna type, termination style, cable specifications, mechanical envelope, environmental rating, and compliance requirements. The 710682 operates across two primary frequency bands (698MHz–960MHz, 1.71GHz–2.7GHz) covering LTE and GNSS/GPS applications, with equivalent gain characteristics and VSWR performance.

Parameter Comparison

Engineering Selection Recommendations

The 4GDPSM is classified as obsolete, making the PCTEL 710682 the primary active alternative. Both components share identical mechanical form factors, environmental ratings, and core RF characteristics (VSWR, gain magnitude, antenna type, and cable specifications).

The 710682 maintains active product status, ensuring availability for procurement and supply chain continuity. Both parts comply with ROHS3 requirements and deliver equivalent performance across overlapping frequency bands. The 710682 operates across two frequency bands versus the 4GDPSM's three bands; applications requiring the 1.575GHz–1.61GHz GNSS band must evaluate whether the 710682's 1.71GHz–2.7GHz coverage satisfies system requirements.

Frequently Asked Questions (FAQ)

Q: Can the 710682 directly replace the 4GDPSM in existing installations?

A: The 710682 is mechanically and electrically compatible with the 4GDPSM for applications requiring LTE cellular (698MHz–960MHz, 1.71GHz–2.7GHz) and GNSS/GPS coverage. Systems dependent on the 1.575GHz–1.61GHz band must confirm the 710682's frequency coverage meets operational specifications.

Q: What is the difference between SMA Male Connector Mount and SMA Male Stud termination?

A: Both termination styles provide SMA Male connectivity. Connector Mount and Stud refer to the physical mounting interface. Compatibility depends on the receiving connector type in the host system.

Q: Are both parts ROHS3 compliant?

A: The 4GDPSM is explicitly ROHS3 compliant. The 710682's RoHS status is not specified in the provided data.

Q: What frequency bands does each antenna cover?

A: The 4GDPSM covers 698MHz–960MHz, 1.575GHz–1.61GHz, and 1.71GHz–2.7GHz. The 710682 covers 698MHz–960MHz and 1.71GHz–2.7GHz, omitting the 1.575GHz–1.61GHz band.

Q: Do both antennas have identical gain characteristics?

A: Both antennas deliver -6.32dBi and 12.05dBi gain across their respective frequency ranges with matching VSWR of 2.
