Harmonic Reject
Apollo offers a wide range of harmonic rejection filters, in terms of harmonics (2nd, 3rd, 4th etc), attenuation values, and power levels. Depending on the specifications, either a waffle iron or alternate high impedance-low impedance design is used. These types of filters are low pass, wide stopband, reactive devices which reflect the stopband frequency.
