The AM81719-030 is a high power silicon NPN 
bipolar transistor designed for Class C, CW communications and telemetry applications in the 1.75
- 1.85 GHz frequency range. 
An emitter site ballasted refractory/gold overlay
die geometry computerized automatic wirebonding 
is employed to ensure long term reliability and 
product consistency.
AM81719-030 is supplied in the industry-standard 
AMPAC hermetic metal/ceramic package.
