This document describes the features and characteristics of the BFG540 series wideband transistors, including high power gain, low noise figure, high transition frequency, and gold metallization for excellent reliability. These transistors are intended for wideband applications in the GHz range, such as analog and digital cellular telephones, cordless telephones, radar detectors, satellite TV tuners, MATV/CATV amplifiers, and repeater amplifiers in fiber-optical systems.
