Embodiment 1
[0026] Such as figure 1 As shown, the equalizer is mainly composed of two series resonant units and two parallel resonant units connected in series via a microstrip transmission line.
[0027] The structure of series resonant unit and parallel resonant unit is as follows figure 2 Shown, attached figure 2 The one on the left is the series resonant unit. The series resonant unit is composed of a resistor, an inductance, and a capacitor in series through a microstrip transmission line and then grounded.
[0028] Attached figure 2 The one on the right is the parallel resonant unit. The parallel resonant unit is composed of a resistor, an inductor and a capacitor in parallel with each other through a microstrip transmission line.
[0029] In this embodiment, R1, L1, and C1 are connected in series and grounded through a microstrip transmission line to form a series resonant unit 1, R2, C2, and L2 are connected in parallel to each other through a microstrip transmission line to form a par...
Embodiment 2
[0037] This embodiment is basically the same as embodiment 1, the difference is that in this embodiment, as Figure 5 As shown, the equalizer is composed of 4 series resonant units in series.
Embodiment 3
[0039] This embodiment is basically the same as embodiment 1, the difference is that in this embodiment, as Image 6 As shown, the equalizer is composed of two parallel resonant units in series.
