BFT92
PNP 5 GHz wideband transistor
Product specification November 1992
NXP Semiconductors Product specification
PNP 5 GHz wideband transistor BFT92
DESCRIPTION PINNING
PNP transistor in a plastic SOT23 PIN DESCRIPTION
envelope.
Code: W1p
It is primarily intended for use in RF lfpage 3

amplifiers, radar systems,
oscilloscopes, spectrum analyzers, 3 collector
etc. The transistor features low 1 2
intermodulation distortion and high

power gain; due to its very high
transition frequency, it also has
excellent wideband properties and
low noise up to high frequencies.
