19-1682; Rev 0; 4/00 UAL IT MAN TION K A ET U E L H A S EV TA WS DA FOLLO 900MHz SiGe, High IP3, Low-Noise Amplifiers Features o Wide Frequency Range: 800MHz to 1000MHz o High Output IP3 and Adjustable +17dBm at 5.3mA +7dBm at 2.8mA o Low Noise Figure: 1.3dB at 900MHz o 13dB Attenuation Step (MAX2642) o On-Chip Output Matching o Low-Power Shutdown Mode o +2.7V to +5.5V Single-Supply Operation o Ultra-Small SC70-6 Package General Description 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.
