Application Scenarios & Design Considerations

Low Noise, High Gain SiGe HBT

Alternative Part Number

  • BGA-8343 --: Qorvo (formerly RFMD) offers the BGA series as a direct replacement for the SGA series; same gain block function and similar frequency range.
  • PGA-103+ --: Mini-Circuits PGA-103+ is a wideband gain block amplifier with comparable gain and low noise, suitable as a functional substitute.
  • MAR-8ASM+ --: Mini-Circuits MAR-8ASM+ is a cascadable MMIC amplifier with similar gain and bandwidth, commonly used as an alternative to SGA-series gain blocks.
  • SBB5089Z --: Wideband InGaP HBT gain block amplifier covering DC-6 GHz with similar gain and P1dB, commonly used as a drop-in replacement for Sirenza SGA-series gain blocks.
  • HMC311SC70 --: InGaP HBT gain block amplifier with similar frequency range and gain characteristics, suitable replacement for SGA-8343Z in RF gain stage applications.
