Product speciﬁcation

NPN 9 GHz wideband transistor

BFR540

FEATURES

• High power gain

• Low noise figure

• High transition frequency

• Gold metallization ensures

excellent reliability.

APPLICATIONS

RF front end 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.
