The YEMD302L1A from Quectel is a 4G/GNSS/Wi-Fi 3-in-1 Combo Antenna that operates from 700-960 MHz/1710-2690 MHz (4G), 2400-2500 MHz/5150-5850 MHz/5925-7125 MHz (Wi-Fi), and 1565-1606 MHz (GNSS). This antenna is designed for applications requiring the antenna to be discrete and it offers backward-compatibility to support 2G, 3G, LTE Cat-M, and NB-IoT. The combo antenna is enclosed in a flame-retardant UL94 V-0 enclosure, which makes it suitable for use in harsh outdoor environments. It provides a peak gain of 5.9 dBi with an efficiency of up to 75.6% and has a VSWR of less than 3.7:1. This linear/RHCP-polarized antenna integrates a low noise amplifier (LNA) that provides a gain of 18 dB with a noise figure of less than 2.5 dB.
The YEMD302L1A ensures a high degree of isolation between the antenna ports to avoid self-interference, resulting in stable and high-speed data connection in the 4G, Wi-Fi, and GNSS bands. The LNA of this antenna requires a DC supply from 2.7 to 3.3 V and consumes 8.3 mA of current. This RoHS-compliant antenna is available in an IP67-rated magnetic/adhesive/screw-mount enclosure that measures 109.28 x 89.00 x 25.80 mm and has SMA (male) connectors. It is ideal for public safety, HD video streaming, utilities and smart cities, automotive vehicle tracking, and fleet management applications.
