The MAX2472/MAX2473 are flexible, wideband, highreverse-isolaTIon buffer amplifiers. The MAX2472 has dualopen-collector outputs capable of delivering -5dBm into50½ while maintaining harmonic suppression below-25dBc. The MAX2473 has a single open-collector outputwith a bias control pin to vary output power from -10dBmto -2dBm while maintaining harmonic suppression below-25dBc. The MAX2472/MAX2473’s combinaTIon of highreverse isolaTIon and low supply current makes them idealfor applicaTIons requiring high performance with lowpower. They feature high input impedance and open-collectoroutputs for maximum flexibility, enabling them to beused 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 -25dBminput power, the MAX2472 consumes 5.2mA, while theMAX2473 consumes only 2.7mA. Both devices are availablein a tiny 6-pin SOT23 package requiring minimalboard space.ApplicationsCellular and PCS Mobile PhonesPrivate Mobile RadiosISM-Band ApplicationsIF/RF OscillatorsGeneral-Purpose Buffers/Amplifiers
