1270FW

Overview

The Amphenol PCTEL 1270FW is a GNSS and GPS module antenna designed for the L1 frequency band. It operates within a range of 1.565 GHz to 1.585 GHz, centered at 1.57542 GHz with a tolerance of ±10 MHz. The component features a TNC female connector with a screw-lock mechanism and utilizes surface-mount device (SMD) installation. It provides a nominal gain of 4.5 dBic and includes an integrated amplifier delivering 26 dB gain at 5 V. This assembly is part of the robust 12700 series, engineered for airborne applications requiring reliable wireless connectivity.

Feature Summary

• Integrated low-noise amplifier providing 26 dB gain at 5 V supply
• TNC female connector with screw-lock retention mechanism
• Surface-mount device (SMD) form factor for PCB integration
• Designed for airborne environments with rigorous environmental testing

Applications

• GNSS receiver systems
• GPS navigation modules
• Airborne electronic equipment
• Aviation communication devices

Procurement Notes

Verify the specific revision status of the 1270FW part number before procurement, as some sources indicate potential discontinuation or legacy status within the manufacturer's portfolio. Confirm that the required 5 V operating voltage aligns with the target system design. Ensure the SMD mounting footprint matches the PCB layout specifications provided in the official datasheet to guarantee mechanical stability during operation.

Selection Notes

Select the 1270FW when a compact, high-gain GNSS solution is required for space-constrained airborne designs. The integrated amplifier simplifies RF chain design by eliminating the need for external amplification stages. Consider the TNC interface if direct cable connection is preferred over U.FL alternatives. Validate that the SMD package type is compatible with the manufacturing process and thermal requirements of the final assembly.

Part Context

The 1270FW belongs to the PCTEL 12700 series, which specializes in ruggedized antennas for critical infrastructure and aviation sectors. This series emphasizes durability and performance under harsh conditions. The component represents a specialized solution for satellite navigation, distinct from general-purpose cellular or Wi-Fi antennas offered by the same manufacturer.

Replacement Considerations

Public records indicate this part may be discontinued by the manufacturer. Verify current availability through authorized distributors. If unavailable, consult the official product lifecycle documentation for recommended cross-references or newer series replacements that maintain TNC female SMD compatibility and similar L1 band performance characteristics.
