300MHz to 2500MHz SiGe

Ultra-Low-Noise Amplifiers

General Description

The MAX2640/MAX2641 are low-cost, ultra-low-noise

amplifiers designed for applications in the cellular, PCS,

GPS, and 2.4GHz ISM frequency bands. Operating from

a single +2.7V to +5.5V supply, these devices consume

only 3.5mA of current while providing a low noise fig-

ure, high gain, high input IP3, and an operating fre-

quency range that extends from 300MHz to 2500MHz.

The MAX2640 is optimized for 300MHz to 1500MHz

applications, with a typical performance of 15.1dB gain,

input IP3 of -10dBm, and a noise figure of 0.9dB at

900MHz. The MAX2641 is optimized for 1400MHz to

2500MHz applications, with a typical performance of

14.4dB gain, an input IP3 of -4dBm, and a noise figure

of 1.3dB at 1900MHz.

These devices are internally biased, eliminating the

need for external bias resistors and chokes. In a typical

application, the only external components needed are a

two-element input match, input and output blocking

capacitors, and a V CC bypass capacitor.

The MAX2640/MAX2641 are designed on a high-fre-

quency, low-noise, advanced silicon-germanium

process and are offered in the space-saving 6-pin

SOT23 package.
