产品概述

The MAX2640/MAX2641 are low-cost, ultra-low-noiseamplifiers designed for applications in the cellular, PCS,GPS, and 2.4GHz ISM frequency bands. Operating froma single +2.7V to +5.5V supply, these devices consumeonly 3.5mA of current while providing a low noise figure,high gain, high input IP3, and an operating frequencyrange that extends from 300MHz to 2500MHz.

The MAX2640 is optimized for 300MHz to 1500MHzapplications, with a typical performance of 15.1dB gain,input IP3 of -10dBm, and a noise figure of 0.9dB at900MHz. The MAX2641 is optimized for 1400MHz to2500MHz applications, with a typical performance of14.4dB gain, an input IP3 of -4dBm, and a noise figureof 1.3dB at 1900MHz.

These devices are internally biased, eliminating theneed for external bias resistors and chokes. In a typicalapplication, the only external components needed are atwo-element input match, input and output blockingcapacitors, and a VCC bypass capacitor.

The MAX2640/MAX2641 are designed on a high-frequency,low-noise, advanced silicon-germaniumprocess and are offered in the space-saving 6-pinSOT23 package.
