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 figure,
high gain, high input IP3, and an operating frequency
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 VCC bypass capacitor.
The MAX2640/MAX2641 are designed on a high-frequency,
low-noise, advanced silicon-germanium
process and are offered in the space-saving 6-pin
SOT23 package.
