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.
