Overview

  • High Power Gain: 19dB (MAX2679), 16.5dB (MAX2679B)
  • Low Noise Figure: 0.95dB (MAX2679), 1.03dB (MAX2679B)
  • Integrated 50Ω Output Matching Circuit
  • Low Supply Current: 1mA (MAX2679), 650μA (MAX2679B)
  • Wide Supply Voltage Range: 1.08V to 1.98V
  • Low Bill of Materials: One Inductor, Two Capacitors, One Resistor
  • 4-Bump, 0.4mm Pitch WLP, 0.83mm x 0.83mm

The MAX2679 and MAX2679B low-noise amplifiers (LNA) are designed for GPS L1, Galileo, and GLONASS applications. The devices achieve high gain and low noise figure while maximizing the input-referred 1dB compression point and the 3rd-order intercept point. The MAX2679 achieves excellent performance while consuming only 1mA supply current and providing 0.95dB noise figure. The MAX2679B achieves excellent performance while consuming only 650µA and providing 1.03dB noise figure.

The MAX2679/MAX2679B operates from a +1.08V to +1.98V single supply. The devices are available in a very small, lead-free, RoHS-compliant, 0.83mm x 0.83mm wafer-level package (WLP).
