The SD1474 is a Class C 28 V common emitter device optimized
for pulsed applications in the 400-500MHz frequency range.
Refractory gold metallization and emitter ballasting ensure long-term
reliability as well as device ruggedness under severe load mismatch
conditions.
SD1474 is characterized for both CW and pulsed operation and is
provided in an industry鈥搒tandard .400鈥?Square hermetic package.
