JCA601

Overview

The JCA601 is a mini external dome GPS active antenna designed for car navigation systems. It operates at the L1 band center frequency of 1575.42±1MHz with a bandwidth of CF±5MHz. The device features right-hand circular polarization (RHCP) and utilizes an SMA connector with 50Ω impedance. Key electrical parameters include a V.S.W.R. of less than 1.5, axial ratio of 3dB (min), and LNA gain of 28±2dB. The physical housing is black plastic with dimensions of 25x25x4mm.

Feature Summary

• Integrated low-noise amplifier providing high signal gain for reliable reception
• Right-hand circular polarization optimized for satellite signal acquisition
• Compact dome design suitable for small vehicle installations

Applications

• Car navigation systems
• GNSS tracking devices
• Automotive telematics units

Procurement Notes
