SiGe PA Technologies

Cost-effective, silicon-based platforms for integrated cellular and Wi-Fi power amplifiers

The GLOBALFOUNDRIES family of silicon germanium (SiGe) BiCMOS power amplifier technologies, SiGe PA, is optimized for standalone and integrated power amplifier solutions in Wi-Fi and cellular applications, including:

  • Smartphones/tablets
  • Access points
  • Macro base stations
  • Small cells
  • IoT devices

The SiGe PA family includes four 350 nm CMOS-based platforms: the newest pair of offerings, SiGe 5PAx and1K5PAx and their earlier counterparts, SiGe 5PAe and 1KW5PAe. Each pair features both 50-ohm and high-resistivity substrate options.
