2J0801CF-C40G-A38G

Overview

The 2J0801CF-C40G-A38G is a connector-mount GNSS active antenna designed for multi-constellation navigation. It supports GPS, GLONASS, BeiDou, QZSS, and Galileo systems within the 1561 MHz to 1606 MHz frequency range. The component features a high gain of 28 dBi and incorporates an integrated pre-filter with a low noise figure to enhance signal integrity. It utilizes an SMA male connector for interface and operates reliably in temperatures ranging from -40 °C to +85 °C.

Feature Summary

• Multi-constellation support for global positioning accuracy
• Integrated pre-filter for improved signal-to-noise ratio
• High gain performance for extended reception range

Applications

• Automotive navigation systems
• Industrial IoT tracking devices
• Maritime navigation equipment

Procurement Notes

Verify that the specific suffix A38G corresponds to the required right-angle configuration and physical dimensions (Ø 13.2 × 19 × 81.5 mm) before procurement. Confirm that the host system provides adequate DC power supply, as this is an active antenna requiring bias voltage for operation. Ensure the mating connector interface matches the SMA male termination specified in the datasheet.

Selection Notes

Select this model when high-gain performance and multi-constellation compatibility are critical for positioning accuracy in challenging RF environments. The integrated pre-filter makes it suitable for applications requiring robust interference rejection. Consider the right-angle form factor if space constraints or cable routing geometry necessitate a non-linear antenna orientation relative to the mounting surface.

Part Context

This component belongs to the 2J Antennas GNSS series, which specializes in active antennas for precise location services. The DEBA series mentioned in general data refers to multiprotocol RF antennas, whereas this specific part number is dedicated to satellite navigation frequencies. It represents a specialized solution for global positioning rather than general-purpose wireless communication protocols.

Replacement Considerations

The standard 2J0801CF-C40G variant offers identical electrical specifications but may differ in mechanical orientation or color. Verify dimensional compatibility and connector alignment when substituting models within the same product family.
