DESCRIPTION
N-P-N silicon planar epitaxial transistor intended for transmitting applications in class-A, B or C in the supply voltages up to 13,5 V. The resistance stabilization of the transistor provides protection against device damage at severe load mismatch conditions. The transistor is housed in a V4" capstan envelope with a ceramic cap. QUICK REFERENCE DATA R.F. performance up to Th = 25 °C in an unneutralized common-emitter class-circuit. MODE OF OPERATION c.w. c.w.
