LLE15180X

DISCRETE SEMICONDUCTORS DATA SHEET LLE15180X NPN microwave power transistor Product specification Supersedes data of September 1994 1997 Feb 18 Philips Semiconductors Product specification NPN microwave power transistor FEATURES Diffused emitter ballasting resistors providing excellent current sharing and withstanding a high VSWR Interdigitated structure provides high emitter efficiency Gold metallization realizes very good stability of the characteristics and excellent lifetime Multicell geometry gives good balance of dissipated power and low thermal resistance Internal input and output prematching ensures good stability and allows an easier design of wideband circuits. APPLICATIONS Intended for use in common emitter, class AB amplifiers in CW conditions for professional applications between 1.4 GHz and 1.6 GHz. DESCRIPTION NPN silicon planar epitaxial microwave power transistor in a SOT437A glued cap metal ceramic flange package, with emitter connected to flange.
