DESCRIPTI ON
The SD1414 is a 12.5 V Class C epitaxial silicon
NPN planar transistor designed for amplifier applications in the 806 - 866 MHz frequency range.
Internal input matching and common base configuration assure optimum gain and efficiency
across the entire frequency band. The SD1414
withstands infinite VSWR at rated power output.
