Application Scenarios & Design Considerations

DC-3500 MHz, Cascadable SiGe HBT MMIC Amplifier

Alternative Part Number

  • BGA-4263 --: Qorvo's BGA series is the direct successor to the Sirenza SGA line; the BGA-4263 offers comparable gain and P1dB in the same SOT-363 package and is the most reliable drop-in replacement.
  • PGA-103+ --: Mini-Circuits PGA-103+ is a wideband Darlington gain block with similar gain and output power, available in SOT-89, and is a well-stocked alternative for general-purpose RF amplification.
  • HMC311SC70 --: ADI HMC311SC70 is a cascadable InGaP HBT gain block covering DC to 6 GHz with comparable gain and OIP3, suitable as a functional substitute when layout can accommodate the SC-70 package.
  • MAR-8ASM+ --: Mini-Circuits MAR-8ASM+ is a low-cost cascadable MMIC amplifier in SOT-363 with comparable gain and bandwidth, commonly used as an alternative to SGA-series gain blocks.
