The BFR90 is a Silicon NPN Planar RF Transistor manufactured by Telefunken, suitable for applications requiring high gain and low noise, such as small-signal amplifiers. It also excels in applications demanding fast switching times.
Key electrical specifications include a typical current-gain bandwidth product (fT) of 5.0 GHz at 14 mA collector current and 10V collector-emitter voltage. The device exhibits a low noise figure (NF) of 2.4 dB at 0.5 GHz and a maximum power gain (Gmax) of 18 dB at 0.5 GHz. The collector current is rated up to 30 mA, with a collector-emitter voltage of 15 Vdc and a collector-base voltage of 20 Vdc.
This transistor is housed in a TO-50 package. The absolute maximum ratings include a total device dissipation of 180 mW at 60°C, with a derating of 2.0 mW/°C above that temperature. The maximum operating temperature is 150°C.
Applications include high-gain, low-noise small-signal amplifiers and circuits requiring fast switching characteristics.
