The BFR182W is a silicon bipolar RF transistor designed for high-frequency applications. Manufactured by Siemens, this transistor is now classified as end-of-life. It was commonly used in various wireless communication and signal amplification circuits. Its features include good gain, low noise, and reasonable linearity for many signal applications.

Applications

• RF Amplifiers
• Oscillators
• Mixers
• High-frequency signal amplification in communication devices.
• Satellite tuners

Features

• Good transition frequency (fT)
• Low noise figure
• High gain
• Good linearity for RF signal integrity
• Small SMD package

Benefits

• Improved signal reception due to low noise.
• Efficient signal amplification.
• Reduced signal distortion.
• Compact size for miniaturization.
• Enhanced performance in wireless circuits.

Typical specifications include parameters such as collector-emitter voltage, collector current, power dissipation, transition frequency, and noise figure. These parameters allowed design engineers to effectively use the transistor in high-frequency circuits. The small surface mount package facilitated its use in miniaturized designs. While end-of-life, the understanding of its capabilities can assist in maintaining older systems and aid in selecting replacement parts.
