Application Scenarios & Design Considerations

DC-4500 MHz, Cascadable SiGe HBT MMIC Amplifier

Alternative Part Number

  • BGA-6389 --: Similar SiGe HBT gain block amplifier in the same frequency range with comparable gain and output power, widely used as a drop-in replacement.
  • PGA-103+ --: Monolithic amplifier offering comparable gain and P1dB in the same band, available in SOT-89 package and commonly substituted for Sirenza gain blocks.
  • HMC311SC70 --: InGaP HBT gain block with similar gain and output compression point, suitable alternative when SGA-6389 is unavailable.
  • MAR-8ASM+ --: Low-cost cascadable MMIC amplifier with comparable gain and output power, suitable substitute when minor performance differences are acceptable.
