## Overview
The YFGA225E3AM is a high-performance GNSS active antenna designed for precise positioning applications. Operating across the 1164–1189MHz and 1559–1606MHz frequency bands, it supports multiple GNSS systems including GPS, GLONASS, GALILEO, BDS, QZSS, and IRNSS, ensuring reliable signal reception.

With dimensions of 39mm x 39mm x 12.1mm and a weight of 23.5g, this compact antenna features a screw mounting design for easy installation. It integrates a ceramic patch with an RF cable (Φ 1.13, black, 100mm) and an IPEX MHF 1 connector.

Boasting a 14 ±3dB LNA gain and ≤ 2.5dB noise figure, it delivers excellent signal amplification and low noise interference. The antenna offers RHCP polarization, 50Ω impedance, and directional radiation, with key performance metrics including 38.8% efficiency at 1176MHz and 56.5% at 1575MHz, along with peak gains of -0.99dBi and -0.18dBi respectively.
