描述 Description

Recommended replacement: MAX2693L
The MAX2693 high-gain, low-noise amplifier (LNA) is designed for GPS L1, Galileo, and GLONASS applications. Built using Maxim's advanced SiGe process, this low-current LNA achieves an ultra-low noise figure while maximizing the input-referred 1dB compression point and the 3rd-order intercept point. The MAX2693 operates from a 1.6V to 3.3V single supply voltage and is optimized for low current, high linearity, and high gain. A shutdown feature reduces the supply current to less than 1μA. The MAX2693 is available in a very small, lead-free, RoHS-compliant, 0.86mm x 0.86mm x 0.65mm, wafer-level package (WLP).

簡(jiǎn)介

MAX2693屬于RF/IF射頻/中頻RFID的射頻放大器。由制造生產(chǎn)的MAX2693射頻放大器在射頻應(yīng)用中，射頻放大器產(chǎn)品可用于信號(hào)增益和緩沖。這些產(chǎn)品與通用運(yùn)算放大器的不同之處在于，它們通常適用于更高的頻率，更傾向于提供不可調(diào)節(jié)的固定增益，并且輸入或輸出阻抗值符合常用傳輸線特性阻抗。
