Alternative Part Number

  • BGA-9189 --: Wideband MMIC amplifier in the same gain/frequency class, commonly used as a drop-in substitute for Sirenza SGA-series gain blocks.
  • MAR-8ASM+ --: Monolithic amplifier with comparable gain and bandwidth, available in surface-mount package and widely cross-referenced for SGA-9189Z applications.
  • ERA-5SM+ --: Similar cascadable 50-ohm gain block with matching frequency range and gain, suitable as a functional replacement when layout is adjusted.
  • SBA-5089Z --: Wideband cascadable gain block amplifier in the same class, offering comparable gain and bandwidth for RF/IF signal chain designs.
  • PGA-103+ --: Monolithic broadband amplifier with similar gain and frequency coverage, widely available and commonly used as a drop-in style replacement.
  • GALI-39+ --: Low-cost cascadable InGaP HBT gain block with comparable performance, suitable for general-purpose RF amplification where exact matching is not critical.
