说明

The MAX2642/MAX2643 low-cost, high third-order intercept point (IP3), low-noise amplifiers (LNAs) are designed for applications in cellular, ISM, SMR, and PMR systems. They feature a programmable bias, allowing the IP3 and supply current to be optimized for specific applications. These LNAs provide up to 0dBm input IP3 while maintaining a low noise figure of 1.3dB.

The gain for these devices is typically 17dB. The MAX2642 also features a 13dB attenuation step, which extends the LNA's dynamic range. Both devices feature a shutdown mode that minimizes power consumption. On-chip output matching saves board space by reducing the number of external components.

The MAX2642/MAX2643 are designed on a low-noise, advanced silicon-germanium (SiGe) process technology. They operate from a +2.7V to +5.5V single supply and are available in the ultra-small 6-pin SC70 package.
