... On-chip output matching saves board space by reduc- ing the number of external components. The MAX2642/MAX2643 are designed on a low-noise, advanced silicon-germanium (SiGe) process technolo- gy. They operate from a +2.7V to +5.5V single supply and are available in the ultra-small 6-pin SC70 package. ...
