JCN047

Overview

The JCN047 is a small size internal GPS PCB antenna manufactured by JC Antenna. It supports active GPS, GLONASS, and BEIDOU systems. The component features an integrated Low Noise Amplifier (LNA) with a gain of 16±2dB and a noise figure of less than 1.5dB. The axial ratio is specified at a maximum of 5dB. The physical dimensions are 15x15x6.5mm or 15x15x4mm depending on the specific variant documentation. The antenna operates with a standard impedance of 50Ω.

Feature Summary

• Supports multi-constellation GNSS including GPS, GLONASS, and BEIDOU
• Integrated LNA for signal amplification
• Compact form factor suitable for space-constrained devices

Applications

• Car trackers
• OBD systems

Procurement Notes

Verify the exact mechanical height specification (4mm vs 6.5mm) against the specific datasheet revision required for your enclosure design. Confirm that the LNA power supply requirements align with your system's voltage rails before integration. Ensure the 50Ω interface matches your RF trace design to maintain signal integrity.

Selection Notes

Select this component when multi-band GNSS reception is required in a compact footprint. The integrated LNA simplifies the RF front-end design by providing necessary gain and noise performance. Consider the specific dimensional constraints of the host device to determine if the 4mm or 6.5mm profile is appropriate for the assembly.
