Method in order to control the profit inclination of the erubiumudopudohuaiba amplifier making use of the intermediate step attenuator

摘要

(57) Abstract According to this invention, control of the profit inclination in the erubiumudopudohuaiba amplifier, is actualized by adjusting the attenuation of the intermediate step variable attenuator which is arranged between the plural erubiumudopudohuaiba amplifier steps. Correct electrical inclination of the input signal is compensated attenuator loss by the fact that it increases, negative electrical inclination is compensated by the fact that attenuator loss is decreased.
