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.
