19-1384; Rev 3; 4/07 EVALUATION KIT AVAILABLE 300MHz to 2500MHz SiGe Ultra-Low-Noise Amplifiers MAX2640/MAX2641 General Description Features The MAX2640/MAX2641 are low-cost, ultra-low-noise Wide Operating Frequency Range amplifiers designed for applications in the cellular, PCS, MAX2640: 300MHz to 1500MHz GPS, and 2.4GHz ISM frequency bands. Operating from MAX2641: 1400MHz to 2500MHz a single +2.7V to +5.5V supply, these devices consume Low Noise Figure only 3.5mA of current while providing a low noise fig- MAX2640: 0.9dB at 900MHz ure, high gain, high input IP3, and an operating fre- MAX2641: 1.2dB at 1575MHz quency range that extends from 300MHz to 2500MHz. 1.3dB at 1900MHz The MAX2640 is optimized for 300MHz to 1500MHz 1.5dB at 2450MHz applications, with a typical performance of 15.1dB gain, High Gain input IP3 of -10dBm, and a noise figure of 0.9dB at MAX2640: 15.1dB at 900MHz 900MHz. The MAX2641 is optimized for 1400MHz to MAX2641: 15.7dB at 1575MHz 2500MHz applications, with a typical performance of 14.4dB at 1900MHz 14.4dB gain, an input IP3 of -4dBm, and a noise figure 13.5dB at 2450MHz of 1.3dB at 1900MHz. High Reverse Isolation These devices are internally biased, eliminating the MAX2640: 40dB at 900MHz need for external bias resistors and chokes. In a typical MAX2641: 31dB at 1575MHz application, the only external components needed are a 30dB at 1900MHz two-element input match, input and output blocking 24dB at 2450MHz capacitors, and a VCC bypass capacitor. +2.7V to +5.5V Single-Supply Operation The MAX2640/MAX2641 are designed on a high-fre- Low 3.5mA Supply Current quency, low-noise, advanced silicon-germanium Ultra-Small SOT23-6 Package process and are offered in the space-saving 6-pinSOT23 package.
