Application Scenarios & Design Considerations

DC-5000 MHz, Cascadable SiGe HBT MMIC Amplifier

Alternative Part Number

  • BGA-4286 --: Qorvo's BGA series is the direct successor to Sirenza's SGA line after acquisition, offering comparable gain and frequency performance in the same application space.
  • PGA-103+ --: Mini-Circuits PGA series provides similar cascadable gain block functionality with matching frequency range, widely available and well documented.
  • MAR-8ASM+ --: Mini-Circuits MAR series is a common drop-in style MMIC amplifier alternative with comparable gain and bandwidth for general RF gain block use.
  • SBA-4086 --: Same SIRENEA amplifier family with comparable gain block architecture, making it a direct functional substitute for the SGA-4286.
  • PMA-5454 --: Wideband MMIC amplifier with similar gain and frequency range, widely available and commonly used as a drop-in replacement for SGA-series parts.
  • GALI-39+ --: Low-cost cascadable gain block with comparable gain and bandwidth, suitable as an alternative when matching SGA-4286 performance requirements.
