DESCRIPTION
The SD1480 is a common emitter 28 V Class C
epitaxial silicon NPN planar transistor designed
primarily for VHF communications applications.
This internally matched device incorporates dif-
fused emitter ballasting resistors nad provides high
gain and stable operation across the entire 136
- 175 MHz VHF communications band.
