BFP843  
Robust low noise broadband pre-matched RF bipolar transistor  
Product description  
The BFP843 is a robust low noise broadband pre-matched RF heterojunction bipolar  
transistor (HBT).  
Feature list  
Unique combination of high end RF performance and robustness: 20 dBm maximum RF input power,  
1.5 kV HBM ESD hardness  
High transition frequency enables best in class noise performance at high frequencies:  
NFmin = 1.2 dB at 5.5 GHz, 1.8 V, 8 mA  
High gain Gma = 17 dB at 5.5 GHz, 1.8 V, 15 mA  
OIP3 = 19.5 dBm at 5.5 GHz, 1.8 V, 15 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)  
Product validation  
Qualified for industrial applications according to the relevant tests of JEDEC47/20/22.  
Potential applications  
WLAN, WiMAX and UWB  
Satellite communication systems: satellite radio (SDARs, DAB) and navigation systems (e.g. GPS, GLONASS,  
BeiDou, Galileo)

Note:  
Gms = IS21 / S12I for k < 1; Gma = IS21 / S12I(k-(k2-1)1/2) for k > 1. In order to get the NFmin values stated in  
this chapter, the test fixture losses have been subtracted from all measured results. OIP3 value  
depends on termination of all intermodulation frequency components. Termination used for this  
measurement is 50 Ω from 0.2 MHz to 12 GHz.
