Wideband VHF amplifier, in particular for television signals, and signal processing device incorporating this amplifier

摘要

Broad band amplifier circuit constructed preferably with hybrid technology and which comprises at least two amplifier stages with transistors (T1, T2) which are not fed back, an input filter (S2, S3, C1, C2, C3,) and an output filter (C6, C7, S5), the said filters being adapted to favour the transmission of the electrical signals in the VHF band and attenuate at least the electrical signals with frequency below this VHF band. The circuit thus designed has in particular noise, gain and linearity characteristics which are improved relative to previous constructions. IMAGE
