MGA-13516 - Low Noise Amplifier

General Description

Avago Technologies’ MGA-13516 is a two stage, easy-touse GaAs MMIC Low Noise Amplifier (LNA) with active bias.

The LNA has low noise with good input return loss and high linearity achieved through the use of Avago Technologies’ proprietary 0.5um and 0.25um GaAs Enhancement-mode pHEMT process.

Key Features

  • Low noise figure.
  • High gain.
  • Good IRL.
  • High linearity performance.
  • High reverse isolation.
  • Externally adjustable supply current.
  • Externally adjustable gain.
  • GaAs E-pHEMT Technology [1].
  • Low cost QFN package.
  • Excellent uniformity in product specifications Specifications 900MHz ; Q1 : 5V, 45mA (typ) Q2 : 5V, 110mA.
  • 31.8 dB Gain.
  • 0.66 dB Noise Figure.

MGA-13516 High Gain, High Linearity, Active Bias, Low Noise Amplifier Data Sheet Description Avago Technologies’ MGA-13516 is a two stage, easy-touse GaAs MMIC Low Noise Amplifier (LNA) with active bias. The LNA has low noise with good input return loss and high linearity achieved through the use of Avago Technologies’ proprietary 0.5um and 0.25um GaAs Enhancement-mode pHEMT process. Both LNAs inside have extra feature that allows a designer to adjust supply current. The first stage has an additional feature where the gain can be adjusted externally without affecting noise figure. Minimum matching needed for input, output and the inter-stage between the two LNA. It is designed for optimum use between 400MHz to 1.5GHz. For optimum performance at higher frequency from 1.4GHz to 2.
