## My Family Essay For School

In the resistive scheme most effectively to use resistance in a collector chain equal to loading resistance. Let's calculate power parameters of the scheme, having accepted identical resistance of loading and collector:

Tension given by the cascade transistor, equally entrance the current given by the previous cascade is almost equal to loading current. Therefore the felt resistance of loading of the cascade equally to a half of resistance, its entrance resistance is also equal to a half of resistance, up to frequencies corresponding =0, It should be considered at calculation of working points of the considered and preterminal cascades.

Technical characteristics NOISE: strip of working frequencies (10-25 MHz; nominal level of the output power of 10 W; coefficient of strengthening of 15 dB; resistance of the generator and loading of 50 Ohms; supply voltage of 18 Century.
