Application Scenarios & Design Considerations

DC-4500 MHz, Cascadable SiGe HBT MMIC Amplifier

Alternative Part Number

  • SBA-5089 --: Cascadable SiGe HBT MMIC amplifier in the same gain-block class with comparable gain and bandwidth, widely used as a drop-in replacement for Sirenza SGA parts.
  • SBB-5089 --: Similar Darlington-style gain block with matching pinout and bias scheme, offering comparable gain and output power for 50-ohm RF designs.
  • HMC311SC70 --: InGaP HBT gain block amplifier covering DC to several GHz with similar gain and P1dB, suitable alternative when Sirenza parts are unavailable.
  • BGA6289 --: Similar cascadable broadband amplifier in the same gain class, widely available and pin-compatible in many RF designs.
  • MAR-6SM+ --: Monolithic amplifier with comparable gain and frequency range, offered in a similar SOT package for drop-in evaluation.
  • ERA-3SM+ --: Wideband gain block with comparable performance and good availability as a general replacement for RF amplifier stages.
