JCN539

Antennas RF Overview

The JCN539 is a GNSS internal active ceramic patch antenna manufactured by JC Antenna. It operates within the frequency range of 1.561GHz to 1.602GHz, with a center frequency of 1.581GHz. The component provides a gain of 5dBic at zenith and maintains a VSWR of less than 1.5. It features an integrated Low Noise Amplifier (LNA) and includes a 100mm cable terminated with an I-PEX connector. Designed for surface mount installation, the antenna has a maximum height of 6.00mm.

Antennas RF Feature Summary

• Integrated low noise amplifier for signal enhancement
• Right-hand circular polarization for GNSS compatibility
• Compact surface mount design with pre-attached cable

Antennas RF Applications

• GNSS navigation systems
• Internal device positioning modules
• GPS/GLONASS/Beidou receivers

Antennas RF Procurement Notes

Verify the specific I-PEX connector generation and LNA voltage requirements against the target system design. Confirm that the 100mm cable length meets spatial constraints within the enclosure. Ensure the surface mount footprint aligns with the PCB layout guidelines provided in the official datasheet to maintain impedance matching and mechanical stability.

Antennas RF Selection Notes

Select this component when a compact, internally mounted solution with built-in amplification is required. The fixed 100mm cable length limits placement flexibility compared to flexible coaxial options. Consider the 6.00mm height profile for clearance requirements. This model is suitable for applications prioritizing low profile and integrated signal conditioning over external mounting versatility.

Antennas RF Part Context
