DESCRIPTION
The SD1477 is a 12.5 V Class C epitaxial silicon
NPN planar transistor designed primarily for VHF
FM communications. This device utilizes diffused
emitter resistors to withstand extremely high VSWR
under rated operating conditions, and is internally
input matched to optimize power gain and effi-
ciency over the 136 - 175 MHz band.
