JCA002

Antennas RF Overview

The JCA002 is an active external GNSS antenna manufactured by JC Antenna, designed for navigation applications. It operates within the UHF frequency group, specifically covering a range of 1.56GHz to 1.61GHz with a center frequency typically around 1575.42MHz. The component features Right-Hand Circular Polarization (RHCP) and requires a DC supply voltage between 2.2V and 5V. Its maximum height is specified as 15.10mm (0.594 inches). The unit includes an SMA connector interface and utilizes adhesive mounting for secure installation.

Antennas RF Procurement Notes

Verify the specific connector variant and mounting style required for your application, as listings may indicate SMA or MMCX interfaces and adhesive or magnetic bases. Confirm that the power supply circuit provides the necessary 2.2V to 5V DC range and current consumption limits. Ensure the operating environment supports the specified frequency range for accurate GNSS signal processing.

Antennas RF Selection Notes

Select this component when a compact, active GNSS solution is required for multi-constellation support including GPS, GLONASS, and Beidou. The adhesive mounting option simplifies integration into devices where drilling or bolting is not feasible. Consider the 15.10mm height constraint for enclosure design. Verify compatibility with the host system's RF interface and power delivery specifications before finalizing the design.

Antennas RF Part Context
