VHF power transistor
DESCRIPTION N-P-N silicon planar epitaxial transistor primarily for use in v.h.f.-f.m. broadcast transmitters. FEATURES • internally matched input for wideband operation and high power gain; • multi-base structure and diffused emitter ballasting resistors for an optimum temperature profile; • gold-metallization ensures excellent reliability. The transistor has a 1⁄2in 6-lead flange envelope with a ceramic cap. All leads are isolated from the flange. QUICK REFERENCE DATA R.F. performance up to Th = 25 °C in an unneutralized common-emitter class-B circuit. MODE OPERATION narrow band; c.w.
