SiGeC microwave NPN
transistor BFU725F
A perfect match up to 20 GHz
Meet the trend towards higher frequencies. With NXP Semiconductors’ latest SiGeC microwave
NPN transistor BFU725F, you get high switching frequencies plus extremely high gain and low noise.
All this in an easy-to-use SOT343F package. It’s the ideal solution for applications up to 20 GHz.
Key features
Ñ
Ñ
Very low noise (0.4 dB at 1.8 GHz / 0.67 dB at 5.8 GHz)
High maximum stable gain (27.8 dB at 1.8 GHz / 10 dB
at 18 GHz)
The NPN microwave transistor BFU725F delivers an unbeatable
blend of high switching frequency, high gain and very low
noise. Thanks to its ultra-low noise figure, it’s perfect for your
sensitive RF receivers particularly those for high-performance
cell phones. Alternatively, with its high cut-off frequency,
it’s your ideal solution for microwave applications in the 10 GHz
to 30 GHz range, such as satellite TV receivers and automotive
collision avoidance radar.

Key benefits
Ñ
SiGeC process delivers high switching frequency from
a silicon-based device
Ñ
Ñ
Cost-effective alternative to GaAs devices
RoHS compliant
The BFU725F get its outstanding performance from our
innovative silicon-germanium-carbon (SiGeC) BiCMOS
process. QUBiC4X was designed specifically to meet the
needs of real-life, high-frequency applications and delivers
an unrivalled fusion of high power gain and excellent dynamic
range. It combines the performance of gallium-arsenide (GaAs)
technologies with the reliability of a silicon-based process.
Key applications
Ñ
Ñ
Ñ
GPS systems
DECT phones
Low noise amplifier (LNA) for microwave
communications systems
Ñ
2nd stage LNA and mixer in direct broadcast satellite (DBS)
low-noise blocks (LNBs)
In addition, with the BFU725F, you don’t need a biasing IC or
negative biasing voltage. So it’s a much more cost-effective
solution than GaAs pHEMT devices.
