Product Brief
The BFR720L3RH is a very low noise wideband NPN RF transistor. The device is based on Infineon’s reliable high volume silicon germanium carbon (SiGe:C) heterojunction bipolar technology. The BFR720L3RH provides a transition frequency fT of 43 GHz and is suited for low voltage applications (VCEO,max = 4 V) from VHF to 12 GHz. Due to its low power consumption the device is very energy efficient and well suited for mobile applications. The BFR720L3RH is housed in a very thin small leadless package ideal for modules.

Features
• Very low noise figure NFmin = 0.45 dB at 1.9 GHz, 0.65 dB at
   5.5 GHz, 3 V, 4 mA
• High power gain Gms = 21 dB at 5.5 GHz, 13 mA, 3 V
• Very thin small leadless package (height only 0.31 mm), hence
   ideal for modules with compact size and low profile height
• Pb-free (RoHS compliant) and halogen-free package
• Qualification report according to AEC-Q101 available
