Alternative Part Number

  • GALI-1+ --: Monolithic amplifier in the same gain/frequency class with similar 50-ohm SOT-89 style package, widely used as a direct functional substitute.
  • ERA-1SM+ --: Same manufacturer's ERA series MMIC amplifier offering comparable gain and bandwidth, pin-compatible in many designs.
  • BGA-1 --: Alternative broadband MMIC amplifier from a different series with similar gain and frequency range, suitable for drop-in evaluation.
  • BGA-1+ --: Low-noise MMIC amplifier in SOT-86 package with comparable gain and bandwidth, suitable alternative when MAR-1SM is unavailable.
  • BGA-101 --: Low-noise silicon MMIC amplifier with comparable gain and frequency coverage, usable as a cross-manufacturer alternative for general-purpose RF amplification.
