<p>The circuit for amplifying the output signal of CATV converter with no modulation distortion and minimum loss comprises an amplifier (1) utilizing a wide band transister (Q1) for amplifying the input signal, a distributer (2) distributing the amplified signal through a directional coupler, a descrambler (3) extracting the descrambling pulse from the distributed signal, a switch (4) switched by the descrambling pulse, and an attenuator (5) attenating the distributed signal selectively.</p> |
