- High linearity (high OIP3)  
- Single positive supply voltage (5 V)  
- RoHS compliant  
- Surface-mount SOT-89 package  

This information is based on the manufacturer's datasheet and specifications.

Application Scenarios & Design Considerations

0.05-6 GHz, Cascadable Active Bias InGaP/GaAs HBT MMIC Amplifier

Alternative Part Number

  • ERA-5SM+ --: Monolithic amplifier in the same gain/bandwidth class, widely used as a drop-in replacement for SBB-series gain blocks.
  • GALI-39+ --: Similar cascadable 50-ohm gain block with comparable gain and output power, available in SOT-89 package.
  • BGA-6289 --: Comparable broadband gain block from a former RFMD-lineage vendor, suitable for similar RF amplifier applications.
  • PGA-103+ --: Wideband MMIC amplifier in the same gain class with similar frequency coverage, available in SOT-89 package and widely stocked as a drop-in style replacement.
  • BGA-2718 --: Silicon germanium broadband amplifier with similar gain and low noise figure, usable as a functional substitute where layout can be adapted.
