Application Scenarios & Design Considerations

DC-3500 MHz, Cascadable SiGe HBT MMIC Amplifier

Alternative Part Number

  • BGA-6489 --: Qorvo's BGA series is a direct functional equivalent to Sirenza's SGA series, offering similar gain and frequency performance in the same package style.
  • PGA-103+ --: Mini-Circuits PGA series provides comparable broadband gain and low noise, widely used as a drop-in alternative for SGA-6489 in RF amplifier designs.
  • HMC311SC70 --: Analog Devices HMC311 offers similar gain and frequency range in a small package, suitable as an alternative with good availability.
  • SNA-186 --: Wideband MMIC amplifier in the same gain class, commonly used as a drop-in replacement for SGA-series gain blocks.
  • MAR-8ASM --: Low-cost cascadable MMIC amplifier with comparable gain and frequency range, suitable for general RF gain-stage substitution.
  • ERA-5SM --: Monolithic amplifier offering similar gain and output power, widely available and often used where SGA-6489 is specified.
