Amplifying circuit arrangement

Abstract From the Canadian patent

In an amplifying circuit arrangement, for example for an, optical receiver in which the light-sensitive components have a high-ohmic output, the receiver is matched to a low-noise low-ohmic amplifier by way of a tuned .lambda./4 circuit having correspondingly selected taps. The optical receiver offers greater sensitivity in a relatively narrow frequency range. Moreover it is frequency, selective and eliminates the great expenditures connected with conventional optical receivers. Broadband amplifying circuit arrangements particularly, optical receivers (E) for for example, cable television, installations contain a passive receiver module (PM) for distortion-free conversion of broadband …
