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-collector 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 available in a tiny 6-pin SOT23 package requiring minimal board space.

Applications

  • Cellular and PCS Mobile Phones
  • General-Purpose Buffers/Amplifiers
  • IF/RF Oscillators
  • ISM-Band Applications
  • Private Mobile Radios (PMRs)

Product Detail

The MAX2472/MAX2473 evaluation kits (EV kits) simplify evaluation of the MAX2472/MAX2473 VCO buffers. They enable performance testing and require no additional support circuitry. All inputs and outputs use SMA connectors to facilitate connection of RF test equipment.

The MAX2472 EV kit is assembled with the MAX2472 and provides a high-impedance input and a pair of open-collector outputs. The EV kit includes a matching network tuned for 900MHz. The MAX2473 EV kit is assembled with the MAX2473 and provides a high-impedance input, a single open-collector output, and a bias control input for setting the output power. Output matches for 600MHz, 1900MHz, or 2400MHz are achieved by replacing the matching components with values provided in the MAX2472/MAX2473 data sheet.

Applications

  • Cellular and PCS Mobile Phones
  • General-Purpose Buffers/Amplifiers
  • IF/RF Oscillators
  • ISM-Band Applications
  • Private Mobile Radios (PMRs)
