NPN 9 GHz wideband transistor
Product specification
BFR540
FEATURES
High power gain
Low noise figure
High transition frequency
Gold metallization ensures
excellent reliability.
DESCRIPTION
The BFR540 is an npn silicon planar
epitaxial transistor, intended for
applications in the RF frontend in
wideband applications in the GHz
range, such as analog and digital
cellular telephones, cordless
telephones (CT1, CT2, DECT, etc.),
radar detectors, satellite TV tuners
(SATV), MATV/CATV amplifiers and
repeater amplifiers in fibre-optic
systems.
The transistor is encapsulated in a
plastic SOT23 envelope.
