DESCRIPTION
The SD4013 is a gold metallized epitaxial silicon
NPN planar transistor using diffused emitter ballast
resistors for superior ruggedness.
The SD4013 can withstand 20:1 VSWR under rated
operating conditions and is internally input matched 1. Collector 3. Emitter
to optimize power gain and efficiency over the 2. Base 4. Emitter
band.
