Application Scenarios & Design Considerations

50MHz to 4000MHz, GaAs pHEMT LOW NOISE MMIC AMPLIFIER

Alternative Part Number

  • SBA-5089Z --: Same vendor family of cascadable InGaP HBT gain blocks in SOT-89 with comparable gain and P1dB, making it a strong drop-in candidate for SPF-5122Z.
  • PGA-103+ --: Wideband monolithic amplifier in SOT-89 with similar gain and output power, widely available and commonly used as a replacement for RFMD SPF-series gain blocks.
  • BGA-824 --: Low-noise SiGe wideband amplifier in SOT-343 offering comparable gain and noise figure, suitable as an alternative when layout can accommodate a different package.
  • BGA-7022 --: Silicon germanium wideband amplifier offering similar gain and bandwidth characteristics, usable as an alternative gain block with minor matching adjustments.
