The APAMPGJ-141 is an active internal patch antenna designed for receiving both GPS (1575.42 MHz) and GLONASS (1592-1610 MHz) signals. It incorporates a pre-filter and a Low Noise Amplifier (LNA) which provides a typical gain of 23 dB at 3V and 24 dB at 5V, operating over a wide supply voltage range from 2.7V to 5.5V. The antenna features Right-Hand Circular Polarization (RHCP), a VSWR of 1.5:1, and a patch gain between 2 and 3 dBic. Its compact size and included U.FL connector on a 100mm micro-coax cable make it ideal for integration into applications like automotive navigation and tracking systems.
