Abstract: 1292395 Image frequency suppression networks INTERNATIONAL STANDARD ELECTRIC CORP 24 July 1970 [24 July 1969] 35963/70 Heading H3U In a superheterodyne receiver in which the mixer oscillator oscillates at a frequency higher than the received signal frequency the image frequency is rejected at a plurality of frequencies within the tunable range. As shown in Fig. 1 a parallel resonant circuit comprising a variable capacitor 1 and an inductor 2 is connected through elements 3, 4, 5 across the signal path extending from antenna 6 to the mixer (not shown). The circuit 1, 2 resonates at the frequency of intelligence signal and has a positive reactive component at the image frequency which decreases as the intelligence signal frequency increases. The impedance of the connection 3, 4, 5 at image frequency has an equal or almost equal negative reactive component, the values of the elements 3, 4, 5 being chosen such that this equal and opposite relationship is true for three different image frequencies. At these frequencies the parallel circuit 1, 2 forms a series resonant circuit with the elements 3, 4, 5. By using more than three elements 3, 4, 5 a correspondingly greater number than three image frequencies may be rejected. In a modification, Fig. 2, the parallel resonant circuit 8, 9 is connected to the elements 10, 11, 12 by means of a tapping on the inductor 9 whereby the impedance of the parallel circuit may be matched to the impedance of the signal path.
