NPN microwave power transistor
FEATURES • Interdigitated structure provides high emitter efficiency • Diffused emitter ballasting resistor provides excellent current sharing and withstanding a high VSWR • Gold metallization realizes very stable 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 • Common emitter class-A amplifiers in CW conditions for military and professional applications in the 1.
