JCA236

Antennas RF Overview

The JCA236 is a high-accuracy GNSS active antenna manufactured by JC Antenna. It operates within the UHF frequency group, specifically covering the range of 1561.098 MHz to 1602 MHz with a center frequency of 1575.42 ± 3 MHz. The component features right-hand circular polarization (RHCP) and provides a gain of 5 dBic at zenith relative to the PCB. Key electrical specifications include a voltage standing wave ratio (V.S.W.R.) of less than 1.5, an impedance of 50 Ω, and a maximum axial ratio of 3 dB. The unit utilizes an SMA connector interface.

Antennas RF Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct configuration. Confirm that the SMA connector type matches the system requirements. Check the product status as active to ensure availability. Validate the lead time information directly with the supplier prior to placing orders. Ensure the adhesive mounting method is compatible with the target application environment.

Antennas RF Selection Notes

Select this component when high-accuracy GNSS reception is required in compact form factors. The active design supports weak signal environments typical in urban or indoor settings. The 50 Ω impedance ensures compatibility with standard RF front-end circuits. Consider the adhesive mounting option for space-constrained PCB layouts where traditional connectors are impractical.
