The BFR505 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, pagers and satellite TV tuners (SATV). The
transistor is encapsulated in a plastic SOT23 envelope.
