The BFG520 is a NPN silicon epitaxial planar Wideband Transistor encapsulated in a plastic envelope. The device is intended for applications in the RF frontend in the GHz range, such as analogue and digital cellular telephones, cordless telephones (CT1, CT2, DECT), radar detectors, pagers and satellite TV tuners (SATV) and repeater amplifiers in fibre-optic systems.
