A Black and White and Color TV Video I-F Output Transistor

A new Fairchild silicon planar transistor has been designed specifically to satisfy the requirements of both black and white and color TV video i-f output stages. Characterization of the transistor is discussed with particular emphasis on the parameters important to this application. The use of Y parameters and a study of gain and stability requirements result in a device characterization which directly relates the device parameters to circuit performance. Specific designs of i-f output stages are considered. Other possible applications of this new device are discussed briefly.
