The BFR99 from Thomson-CSF is a PNP silicon planar epitaxial transistor specifically engineered for wide band common-emitter linear amplifier applications up to 1GHz. It features a high transition frequency (fT) of 2 GHz at 10mA, low reverse capacitance (Cre) of 0.4 pF at 1MHz, and good cross-modulation properties with low noise.
This transistor operates with a maximum collector current of 50mA and can handle collector-emitter voltages up to -25V. Power dissipation is rated at 225mW at ambient temperature and 360mW at case temperature, both at 25°C. The operating temperature range is from -55°C to 200°C.
The BFR99 is housed in a Jedec TO-72 metal case, suitable for through-hole mounting. Its electrical characteristics include a DC current gain (hFE) ranging from 20 to 80 depending on the collector current, and a base-emitter voltage of -0.75V typical at -10mA.
Key electrical parameters include a collector cutoff current (ICBO) of -100nA at -15V, and breakdown voltages of -25V for collector-base (VCBO) and collector-emitter (VCEO), and -3V for emitter-base (VEBO).
Noise figure measurements show typical values of 2.5dB at 200MHz and 3.5dB at 800MHz for a collector current of 3mA, and 3dB at 200MHz and 4dB at 800MHz for a collector current of 10mA, with a source resistance of 50 Ohms.
