Alternative Part Number

  • BGA-5389 --: Qorvo acquired RFMD's RF component portfolio; the BGA-series Darlington amplifier is a direct functional equivalent to the SGA-5389 with similar gain and frequency range.
  • MAR-8ASM+ --: Wideband monolithic amplifier in a similar package offering comparable gain and bandwidth, commonly used as a drop-in replacement for SGA-series gain blocks.
  • ERA-5SM+ --: Monolithic amplifier with similar gain and frequency characteristics, suitable as an alternative gain block when the SGA-5389 is unavailable.
