1357D-15CM-UFL

Overview

The Amphenol PCTEL 1357D-15CM-UFL is a GNSS ceramic patch antenna designed for surface mount applications. It operates within the L1 band, covering frequencies from 1565.42 MHz to 1585 MHz with a center frequency of 1575.2 MHz. The component features an integrated Low Noise Amplifier (LNA) and a filter to enhance signal integrity. It utilizes a U.FL connector interface and includes a 15 cm cable length. The maximum power rating is specified at 50 W, ensuring robust performance in various RF environments.

Feature Summary

• Integrated Low Noise Amplifier and filter for improved signal reception
• Ceramic patch construction optimized for GNSS applications
• Surface mount design with pre-attached 15 cm cable
• U.FL connector interface for compact integration

Applications

• GPS navigation systems
• GNSS tracking devices
• Telematics modules
• Mobile device positioning

Procurement Notes

Verify the specific suffix '15CM' confirms the 15 cm cable length variant when sourcing. Ensure compatibility with U.FL mating connectors on the host PCB or assembly. Confirm that the surface mount footprint matches the mechanical dimensions provided in the official datasheet to avoid assembly issues.

Selection Notes

Select this model when a fixed-length 15 cm cable is required for internal routing within compact enclosures. The integrated LNA provides necessary gain for weak satellite signals without requiring external amplification stages. Consider the U.FL termination if space constraints prohibit direct PCB mounting of the antenna element itself.

Part Context

This part belongs to the 1357D series of GNSS antennas from Amphenol PCTEL. The series offers various cable length options, such as 5 cm and 11 cm variants, to suit different form factors. All models share the same core ceramic patch technology and LNA/filter integration, differing primarily in cable length and connector type.

Replacement Considerations

Direct substitutes include other 1357D variants with different cable lengths, such as 1357D-5CM-UFL or 1357D-11CM-UFL, if cable routing allows modification. Cross-brand replacements require matching the 1575.2 MHz center frequency, U.FL interface, and surface mount package.
