The MAX2640/MAX2641 are low-cost, ultra-low-noise amplifiers designed for applications in the cellular, PCS, GPS, and 2.4GHz ISM frequency bands.
The MAX2640 and MAX2641 are low‑cost, ultra‑low‑noise amplifiers designed for cellular, PCS, GPS and 2.4 GHz ISM applications. They operate from a single +2.7 V to +5.5 V supply and draw only 3.5 mA of current.
Key features include wide frequency coverage (300 MHz‑2.5 GHz), high gain (up to 15.1 dB), low noise figures (as low as 0.9 dB), high reverse isolation, and a compact 6‑pin SOT23‑6 package. Typical designs require only five external components.
