SD1477 RF POWER BIPOLAR TRANSISTORS VHF MOBILE APPLICATIONS FEATURES SUMMARY 175 MHz Figure 1. Package 12.5 VOLTS COMMON EMITTER POUT = 100 W MIN. WITH 6.0 dB GAIN 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 efficiency over the 136 - 175 MHz band. .500 6L FL (M111) epoxy sealed Figure 2.
