RF POWER BIPOLAR TRANSISTORS VHF MOBILE APPLICATIONS

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.
