UHF linear push-pull power
transistor
FEATURES • internally matched input for wideband operation and high power gain • internal midpoint (r.
f.
ground) reduces negative feedback and improves power gain • increased input and output impedances (compared with single-ended
transistors) simplify wideband matching • length of the external emitter leads is not critical • diffused emitter ballasting resistors for an optimum temperature profile • gold metallization ensures excellent reliability.
