Reception amplifier, in particular for a television receiver and the use of the receiving amplifier

摘要

Reception amplifier, in particular for a television receiver, comprising:– a first input terminal (8);– a semiconductor body (2) with a first node (4) and at least one second node (5);– a in the semiconductor body (2) an integrated amplifier circuit (1) comprising a differential amplifier with a first and a second field effect transistor (t1, t2), the control terminals of a first input (12) and a second input (13) of the amplifier circuit (1) and a between the first and second input (12, 13) which is arranged in the capacitive element (cin);– a in its resonant frequency tunable resonant circuit, comprising:– a in the semiconductor body (2) integrated in its capacitance adjustable element (c_T) with a control input (90) and which, by means of its connections to the first and the second input (12, 13) and parallel to the capacitive element (cin) of the integrated amplifier circuit (1) is connected;– at least a first inductive element (l₁''), the with a first connection to the first input (12) and..
