BFR505/T1 NXP

BFR505 NPN 9 GHz wideband transistor Rev. 4 7 September 2011 Product data sheet 1. Product profile 1.1 General description The BFR505 is an NPN silicon planar epitaxial transistor, intended for applications in the RF front end 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. 1.2 Features and benefits High power gain Low noise figure High transition frequency Gold metallization ensures excellent reliability. 1.3 Quick reference data Table 1.
