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 in-

ternally input matched to optimize power gain and

efficiency over the 136 - 175 MHz band.
