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.
