500MHz to 2500MHz
VCO Buffer Amplifiers
General Description
The MAX2472/MAX2473 are flexible, wideband, high-
reverse-isolation buffer amplifiers. The MAX2472 has dual
open-collector outputs capable of delivering -5dBm into
50Ω 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/MAX2473’s 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.
