DESCRIPTION
The AM81719-040 is a high power silicon NPN
bipolar transistor designed for Class C, CW com-
munications and telemetry applications in the
1.75 - 1.85 GHz frequency range.
An emitter-ballasted refractory-gold overlay die
geometry with computerized automatic wire-
bonding is employed to ensure long-term reliabil-
ity and product consistency.
