Product Summary

The BFQ3401 is an NPN 4 GHz wideband transistor encapsulated in a 4 lead SOT122A envelope with a ceramic cap. All leads are isolated from the stud. The BFQ3401 is primarily intended for driver and final stages in MATV system amplifiers. It is also suitable for use in low power band IV and V equipment. Diffused emitter-ballasting resistors and the application of gold sandwich metallization ensure an optimum temperature profile and excellent reliability properties. The BFQ3401 also features high output voltage capabilities.
