BFP840FESD
Overview
The BFP840FESD is a discrete RF heterojunction bipolar transistor (HBT) with an integrated ESD protection suitable for 5 GHz band applications.
Summary of Features
- Unique combination of high end RF performance and robustness: 20 dBm maximum RF input power, 1.5kV HBM ESD hardness
- High transition frequency fT = 85 GHz to enable best in class noise figure at high frequencies: NFmin = 0.75 dB at 5.5 GHz, 1.8 V, 5 mA
- High gain Gms = 23 dB at 5.5 GHz, 1.8 V, 10 mA
- OIP3 = 22 dBm at 5.5 GHz, 1.8 V, 10 mA
- Suitable for low voltage applications e.g. VCC = 1.2 V and 1.8 V (2.85 V, 3.3 V, 3.6 V require a corresponding collector resistor)
- Low profile and small form factor leadless package
Potential Applications
- Wireless communications: WLAN 2.4 GHz and 5-6 GHz bands, WiMAX and UWB
- Satellite communication systems: satellite radio (SDARs, DAB), navigation systems (e.g. GPS, Glonass, Beidou, Galileo)
