SD1477 RF POWER BIPOLAR TRANSISTORS VHF MOBILE APPLICATIONS FEATURES SUMMARY Figure 1. Package ■ 175 MHz ■ 12.5 VOLTS ■ COMMON EMITTER )■ POUT = 100 W MIN. WITH 6.0 dB GAIN duct(sDESCRIPTION roThe SD1477 is a 12.5 V Class C epitaxial silicon NPN planar transistor designed primarily for VHF PFM communications. This device utilizes diffused teemitter resistors to withstand extremely high leVSWR under rated operating conditions, and is in- ternally input matched to optimize power gain and bsoefficiency over the 136 - 175 MHz band. .500 6L FL (M111) epoxy sealed Figure 2.
