Descriptive summary

The fT-ITC curve represents Transition Frequency (fTT) characteristics as a function of collector current (ITC) for the six generations of RF wideband transistors. A group of transistors having the same collector current (ITC) & similar transition frequencies (fTT) represents a curve. The curve number matches products in the table, detailing their RF characteristics.
