Abstract
Abstract THE PRESENT INVENTION RELATES TO A HIGH FREQUENCY AMPLIFIER ARRANGEMENT WITH SEVERAL RESONANT-LINE CIRCUITS (E.G. TELEVISION TUNER) WHERE THE INNER CONDUCTORS AND THE OUTER CONDUCTORS OF THE RESONANT-LINE CIRCUITS ARE ARRANGED ON A METAL COATED CARRIER PLATE, THE INNER CONDUCTORS BEING ARRANGED ON BEHIND THE OTHER AND RESTING WITH ITS ENDS ON A SIDE EDGE OF SAID CARRIER PLATE, WHICH IS INSERTED IN AN AMPLIDIER BASE PLATE. THE BASE PLATE, WHICH CARRIES THE RELEVANT CIRCUIT ELEMENTS AND IF NECESSARY OTHER AMPLIFIER STAGES, IS DIP SOLDERED WITH THE INSERTED CARRIER PLATE. TWO ENDS OF TWO INNER CONDUCTORS FACING ONE ANOTHER MAY BE GROUNDED BY A COMMON INDUCTANCE CONSISTING OF TWO CONDUCTORS COUPLED WITH ONE ANOTHER, WHEREAS THE OTHER ENDS OF THE TWO INNER CONDUCTORS ARE GROUNDED ACROSS A TUNING CAPACITANCE.
