MAX2473EUT-T
500MHz to 2500MHz VCO Buffer Amplifiers
General DescriptionThe MAX2472/MAX2473 are flexible, wideband, high-
reverse-isolation buffer amplifiers. The MAX2472 has dual
open-collector outputs capable of delivering -5dBm into
50Ωwhile 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1:Limits are 100% production tested at TA= +25°C. Limits over the entire operating temperature range are guaranteed by
design and characterization but are not production tested.
Note 2:This is the recommended operating frequency range. The parts have been characterized over the specified frequency
range and production tested at 900MHz. Operation outside of this range is possible but not guaranteed.
Note 3:Guaranteed by design and characterization.
