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.
