Philips Semiconductors Product specification
NPN 9 GHz wideband transistor BFG520; BFG520/X; BFG520/XR
FEATURES
• High power gain
• Low noise figure
• High transition frequency
• Gold metallization ensures
excellent reliability.
DESCRIPTION
NPN silicon planar epitaxial
transistors, intended for applications
in the RF frontend in the GHz range,
such as analog and digital cellular
telephones, cordless telephones
(CT1, CT2, DECT, etc.), radar
detectors, pagers and satellite TV
tuners (SATV) and repeater
amplifiers in fibre-optic systems.
The transistors are encapsulated in
4-pin, dual-emitter plastic SOT143
and SOT143R envelopes.
