MAX2659ELT+T-GPS / GNSS低噪声放大器
MAX2659ELT+T General Description
MAX2659ELT+T 概述
The MAX2659 high-gain, low-noise amplifier (LNA) isdesigned for GPS, Galileo, and GLONASS applications.Designed in Maxim’s advanced SiGe process, the device achieves a 20.5dB gain and an ultra-low-noise figure of 0.8dB while maximizing the input-referred 1dB compression point and the 3rd-order intercept point at-12dBm and -5dBm, respectively.
The MAX2659 operates from a +1.6V to +3.3V single supply and consumes only 4.1mA. The shutdown feature in the device reduces the supply current to be less than 1μA. The MAX2659 is available in a very small,lead-free, RoHS-compliant, 1.5mm x 1.0mm x 0.75mm,6-pin μDFN package.
低噪声放大器（LNA）是专为GPS，Galileo和GLONASS应用。在Maxim先进的SiGe工艺设计，在提供20.5dB增益和0.8分贝的超低噪声系数的同时，可使输入参考1dB压缩点和-12 dBm的分别和-5dBm，三阶截取点。
MAX2659采用+ 1.6V至+3.3V单电源仅消耗4.1mA电流。在设备停机功能可将电源电流小于1μA。该MAX2659是在一个非常小的，无铅，符合RoHS标准可用，1.5毫米X1.0毫米X0.75毫米，6引脚μDFN封装。
