The series FHP high pass filter is designed and constructed to provide a sharp skirt selectivity of low frequency with minimum insertion loss in the passband. The typical insertion loss is 0.7 dB in K-Band, and increases to about 1.5 dB in W-Band. The insertion loss is determined by the corner frequency and selectivity.
