BFG540; BFG540/X; BFG540/XR
General description
NPN silicon planar epitaxial transistors, intended for wideband applications in the GHz range, such as analog and digital cellular telephones, cordless telephones (CT1, CT2, DECT, etc.), radar detectors, satellite TV tuners (SATV), MATV/CATV amplifiers and repeater amplifiers in fibre-optical systems.
The transistors are mounted in plastic SOT143B and SOT143R packages.
Features
- High power gain
- Low noise figure
- High transition frequency
- Gold metallization ensures excellent reliability.
