The YEMA206J1AM from Quectel is a 4G and GNSS Combo Antenna that operates from 698 to 960 MHz (4G) and 1559 to 1606 MHz (GNSS). It is optimized to provide broadband cellular coverage while supporting multi-constellation GNSS reception and is compatible with 2G, 3G, LTE Cat-M, and NB-IoT applications. This combo antenna is suitable for applications requiring a compact, low-profile antenna and can be used with Quectel's RM520x series modules. It supports linear (4G) and RHCP (GNSS) polarization, provides a peak gain of up to 3.3 dBi with an efficiency of up to 63.3%, and has a VSWR of less than 3.30:1.
The YEMA206J1AM integrates a GNSS LNA with 16 dB of gain and a noise figure below 2.5 dB, along with an integrated filter delivering more than 45 dB of out-of-band rejection. The LNA requires a 2.7 to 3.3 V DC supply and draws 4.3 mA of current. This 50-ohm antenna is available in an adhesive-mount ABS+PC enclosure measuring 82.0 × 18.2 mm and has an SMA (male) connector. The enclosure is IP67-rated, making it suitable for harsh outdoor environments. It is ideal for fleet management, automotive tracking, smart city infrastructure, utilities, public safety, and other IoT applications.
