JTT1575S35P3X

Antennas RF Overview

The JTT1575S35P3X is a GPS patch antenna manufactured by JC Antenna, designed for UHF frequency applications within the 1GHz to 2GHz range. It operates at a center frequency of 1.575GHz with a bandwidth of 6MHz (1.572GHz to 1.578GHz). The component provides a gain of 6.5dBi and features a maximum height of 0.118 inches (3.00mm). It is specified as a ceramic antenna type with a 50Ω impedance.

Antennas RF Feature Summary

• High gain performance of 6.5dBi for enhanced signal reception
• Low profile design with a maximum height of 3.00mm
• Optimized for GPS L1 band operations

Antennas RF Applications

• GPS navigation systems
• GNSS tracking devices
• Automotive telematics

Antennas RF Procurement Notes

Verify the specific datasheet version from JC Antenna to confirm mechanical dimensions and mounting requirements. Ensure compatibility with the intended ground plane size, as patch antenna performance is highly dependent on the reference ground. Cross-reference the DigiKey part number 4034-JTT1575S35P3X-ND for supply chain availability.

Antennas RF Selection Notes

Select this model when high gain is required in a low-profile form factor for GPS applications. Compare against lower gain variants like the JTT1575S20P4X if space constraints are less critical but cost or size reduction is prioritized. Ensure the operating environment supports the standard commercial temperature range unless otherwise specified.

Antennas RF Part Context

JC Antenna specializes in GNSS, 4G/5G, and WiFi solutions for IoT applications. The JTT series represents their patch antenna lineup, offering various sizes and gain configurations. This model is part of their broader portfolio of RF antennas designed for reliable wireless communication in constrained spaces.

Antennas RF Replacement Considerations

The JTT1575S20P4X is a documented alternative with lower gain (2dBi) and different dimensions. Verify that the reduced gain meets system link budget requirements before substituting.
