MAX2642EXT+T

The MAX2642EXT+T is a 900MHz SiGe, high IP3, low noise amplifier (LNA) in 6 pin SC-70 package. This low cost, high third order intercept = point (IP3) LNA is designed for applications in cellular, ISM, SMR and PMR systems. It features a programmable bias, allowing IP3 and supply current to be optimized for specific applications. This LNA provides up to 0dBm input IP3 while maintaining a low noise figure of 1.3dB. The gain for this device is typically 17dB. The MAX2642 also features a 13dB attenuation step which extends LNA's dynamic range. It also features a shutdown mode that minimizes power consumption. On-chip output matching saves board space by reducing the number of external components. The MAX2642 is designed on a low noise, advanced silicon germanium (SiGe) process technology. Typical applications include 800MHz/900MHz cellular phones, 900MHz cordless phones, 868MHz/900MHz ISM band wireless data and PMR/SMR/LMR.
