00 — Overview

What the AT2659 family does

The AT2659 is a low noise amplifier (LNA) chip for L1 band global satellite navigation, supporting GPS, BeiDou, Galileo, and Glonass systems. It features a typical noise figure of 0.80 dB, 21.5 dB power gain, and -14 dBm input P1dB. The device operates across 1550 MHz to 1615 MHz with 4.3 mA current consumption and a 1.4 V to 3.6 V supply range. This component is typically used in automatic navigation, positioning mobile devices, personal navigators, integrated GPS phones, notebooks, underwater navigation, and aviation equipment.
