This circuit uses a dual - loop input with band-pass filter to make great prestage selection. It uses MOS prestage and followed ring mixer IC to make high signal intensity. It connects a dual-loop-pass filter between prestage and ring mixer stage in order to achieve good image frequency selection.The main coil data:L1 : o.5mm copper enameled wires with 1 turns;L2, L3, L5:0.8mm copper and silver wires with 5 turns ;L4 : 6 turns , L5 : 5 turns. L4, L5 are 0.8mm copper and silver wires;L6 : 2 turns , L7: 7 turns , L8 : 2 turns , L9 : 12 turns . L6 ~ L9 are 0.5mm copper enameled wires;L9: 12 turns , L10: 2 turns , L11: 12 turns . L9 ~ L11 are copper enameled wires.
