300MHz to 2500MHz SiGe  
Ultra-Low-Noise Amplifiers  
General Description  
Features  
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.  
♦ Wide Operating Frequency Range  
MAX2640: 300MHz to 1500MHz  
MAX2641: 1400MHz to 2500MHz  
♦ Low Noise Figure  
MAX2640: 0.9dB at 900MHz  
MAX2641: 1.2dB at 1575MHz  
1.3dB at 1900MHz  
1.5dB at 2450MHz  
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.  
♦ High Gain  
MAX2640: 15.1dB at 900MHz  
MAX2641: 15.7dB at 1575MHz  
14.4dB at 1900MHz  
13.5dB at 2450MHz  
♦ High Reverse Isolation  
MAX2640: 40dB at 900MHz  
MAX2641: 31dB at 1575MHz  
30dB at 1900MHz  
24dB at 2450MHz  
♦ +2.7V to +5.5V Single-Supply Operation  
♦ Low 3.5mA Supply Current  
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  
bypass capacitor.  
CC  
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.
