BFG520
NPN 9 GHz wideband transistor
NPN silicon planar epitaxial transistor, 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.
