♦ +2.7V to +5.5V Supply Range

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.

♦ 500MHz to 2500MHz Input Frequency Range

♦ High Reverse Isolation: 49dB at 900MHz

♦ Dual Open-Collector Outputs (MAX2472)

♦ Adjustable -10dBm to -2dBm Output Power

Control (MAX2473)

♦ High Input Impedance: >250Ω at 900MHz

♦ Ultra-Small SOT23-6 Package

Ord e rin g In fo rm a t io n

Both the MAX2472 and MAX2473 operate from a single

+2.7V to +5.5V supply. With V

= +3.0V and -25dBm

TEMP.

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.
