500mhz To 2500mhz Vco Buffer Amplifiers

The MAX2472 MAX2473 are flexible, wideband, high- reverse-isolation Buffer Amplifiers The MAX2472 has dual open-collector outputs capable of delivering -5dBm into 50 while maintaining harmonic suppression below -25dBc. The MAX2473 has a single open-collector output with a bias control pin to vary output power from -10dBm to -2dBm while maintaining harmonic suppression below -25dBc. The MAX2472 MAX2473s combination of high reverse isolation and low supply current makes them ideal for applications requiring high performance with low power. They feature high input impedance and open-col- lector outputs for maximum flexibility, enabling them to be used with a variety of Oscillator topologies. Both the MAX2472 and MAX2473 operate from a single +2.7V to +5.5V supply. With VCC = +3.0V and -25dBm input power, the MAX2472 consumes 5.2mA, while the MAX2473 consumes only 2.7mA. Both devices are avail- able in a tiny 6-pin SOT23 package requiring minimal board space. By Maxim Integrated Products
