The MAX2470/MAX2471 are flexible, low-cost, high-

reverse-isolation buffer amplifiers for applications with

discrete and module-based VCO designs. Both feature

differential 50Ω outputs for driving a single differential

(balanced) load or two separate single-ended (unbal-

anced) 50Ω loads. The MAX2470 offers a single-ended

input and has two selectable frequency ranges of oper-

ation: 10MHz to 500MHz and 10MHz to 200MHz. The

MAX2471 offers a differential input and operates from

10MHz to 500MHz. The MAX2470/MAX2471 also feature

high input impedance for maximum flexibility, enabling

them to be used with a variety of oscillator topologies.

High reverse isolation combined with low supply current

make them ideal for applications requiring high perfor-

mance with low power.

♦ +2.7V to +5.5V Supply Range

♦ Input Frequency Range

High: 10MHz to 500MHz (MAX2470/2471)

Low: 10MHz to 200MHz (MAX2470)

♦ >14dB Power Gain at 200MHz

♦ 64dB Typical Reverse Isolation at 200MHz

♦ Low-Distortion Output Drive

♦ Ultra-Small SOT23-6 Package

♦ High Input Impedance

♦ Single-Ended (MAX2470) or Differential

(MAX2471) Inputs

These devices are also ideal for use as active baluns.

The MAX2470 converts a single-ended input to a differ-

ential output. The MAX2471 is useful as a differential

buffer stage or to convert from a differential input to two

single-ended outputs.

The MAX2470 operates from a single +2.7V to +5.5V

supply. At -5dBm output power, it consumes 5.5mA in

the hig h-fre q ue nc y ra ng e a nd only 3.6mA in the

low-frequency range. The MAX2471 operates from a

+2.7V to +5.5V single supply and consumes 5.5mA.

Both devices are available in ultra-small SOT23-6 plas-

tic packages, requiring minimal board space.
