  • Ultra-Low-Noise Figure: 0.8dB
  • Integrated 50Ω Output Matching Circuit
  • Low Supply Current: 4.1mA (MAX2657)
  • Wide Supply Voltage Range: 1.6V to 3.3V
  • Low Bill of Materials: One Inductor, Two Capacitors

  • 0.4mm-Pitch Wafer-Level Package (WLP)

The MAX2657/MAX2658 high-gain, low-noise amplifiers (LNAs) are designed for GPS L1, Galileo, and GLONASS applications. Designed in Maxim's advanced SiGe process, the devices achieve a high gain and an ultra-low-noise figure while maximizing the input-referred 1dB compression point and the 3rd-order intercept point.

The MAX2657/MAX2658 operate from a +1.6V to +3.3V single supply. The MAX2657 is optimized for low current. The MAX2658 is optimized for high linearity. The shutdown feature in the device reduces the supply current to be less than 1µA. The MAX2657/MAX2658 are available in a very small, lead-free, RoHS-compliant, 0.86mm x 1.26mm x 0.65mm, wafer-level package (WLP).
