YEMA500J1AH

Antennas RF Overview

The Quectel YEMA500J1AH is a low-profile external antenna module designed for 4G, 5G, and GNSS applications. It supports 5G*4 and GNSS L1&L5 bands with an integrated LNA providing 28dB gain. The unit features an adhesive mount, SMA male connector, and a 1300mm cable. Dimensions are 264.6 x 161.2 x 30.6 mm. It meets IP67 and IP69K ingress protection standards and complies with UL 94 V-0 and RoHS/REACH regulations.

Antennas RF Feature Summary

• Integrated Low Noise Amplifier (LNA) with 28dB gain for signal enhancement
• Multi-band support combining 5G cellular and dual-frequency GNSS L1/L5 reception
• Robust environmental sealing rated IP67 and IP69K for harsh conditions
• Low-profile design utilizing adhesive mounting for secure installation

Antennas RF Applications

• IoT modules requiring combined cellular and positioning capabilities
• LTE and M2M communication devices
• Wi-Fi module integration scenarios
• Remote monitoring and control systems
• Vehicular telematics and digital signage

Antennas RF Procurement Notes

Verify the specific datasheet version to confirm exact frequency ranges and impedance specifications prior to integration. Ensure the SMA male connector interface matches the host device port. Confirm that the adhesive mounting surface is compatible with the intended installation environment. Check for any regional supply restrictions or limited availability status before finalizing procurement plans.

Antennas RF Selection Notes

Select this model when both 5G connectivity and precise GNSS positioning via L1/L5 bands are required in a single compact unit. The integrated LNA makes it suitable for applications where signal strength may be compromised. The adhesive mount option simplifies installation compared to screw-mounted alternatives. Verify that the 1300mm cable length accommodates the physical layout of the target equipment.

Antennas RF Part Context

This component belongs to Quectel's Wireless Solutions external antenna portfolio. It is engineered for robust performance in industrial and commercial IoT deployments. The product integrates multiple radio technologies into a single housing to reduce system complexity. It is part of a broader range of antennas supporting various cellular and satellite navigation standards.

Antennas RF Replacement Considerations

Consider the YEMA600J1AH if 5G*2 support is sufficient instead of 5G*4. Evaluate the YEMN402J1AH for screw-mount requirements rather than adhesive. Check for updated Quectel models offering different cable lengths or connector types if the current configuration does not fit the mechanical design.
