The Joymax PLF-C025cc4B antenna is an embedded, RHCP, stacked ceramic patch antenna integrated with a 2-stage LNA, designed for GNSS frequency bands (1176.45 MHz, 1127.6 MHz, 1559~1608 MHz), supporting GPS (L1, L2, L5), GALILEO (E1, E5a), GLONASS (G1), BeiDou/Compass (B1, B1C, B2a), QZSS (L1, L2, L5), IRNSS (NavIC) for Navigation, Location, and Timing applications.
The embedded antenna has a coax cable terminated in a MHF Plug connector. The antenna may be mounted inside an end-product’s enclosure by mechanical means (e.g. bracket, adhesive - not included), or by soldering the LNA shielding case to the main PCB.
