Additional Notes:

1.

50 Ω source and 50 Ω load impedance. See Fig 2 and 3 for differential mode attenuation in the 20 kHz-100 MHz frequency range.

2.

50 Ω source and 50 Ω load impedance; external common-mode capacitors 0.1 µF (from IN+ and IN- to the common chassis). See

Fig. 4 for attenuation in the 20 kHz-100 MHz frequency range.
