Summary of Features:
  • Low noise broadband NPN RF transistor based on Infineon´s reliable, high volume SiGe:C bipolar technology
  • High maximum RF input power and ESD robustness 20 dBm maximum RF input power, 1.5 KV HBM ESD hardness
  • Unique combination of high RF performance, robustness and ease of application circuit design
  • Low noise figure: NFmin = 0.95 dB at 2.4 GHz and 1.05 dB at 5.5 GHz, 1.8 V, 8 mA
  • High gain |S21|2 = 21.5 dB at 2.4 GHz and 16.5 dB at 5.5 GHz, 1.8 V, 15 mA
  • OIP3 = 21.5 dBm at 2.4 GHz and 20.5 dBm at 5.5 GHz, 1.8 V, 20 mA
  • Ideal for low voltage applications e.g. VCC = 1.2 V and 1.8 V (2.85 V, 3.3 V, 3.6 V requires corresponding collector resistor)
  • Low power consumption, ideal for mobile applications
  • Pb-free (RoHS compliant) and halogen free very small thin leadless plastic package
  • Qualification report according to AEC-Q101 available
Target Applications:
  • Wireless Communications: WLAN IEEE802.11b,g,n,a,ac single- and dual band applications, broadband LTE or WiMAX LNA
  • Satellite navigation systems (e.g. GPS, GLONASS, COMPASS...) and satellite C-band LNB (1st and 2nd stage LNA)
  • Broadband amplifiers: Dualband WLAN, multiband mobile phone, UWB up to 10 GHz
  • ISM bands up to 10 GHz
  • Dedicated short range communication (DSRC) systems: WLAN IEEE802.11p
