Abstract :
In this paper, high selectivity and flat group delay parallel-coupled microstrip bandpass filter with lump element K-inverter are proposed. By using delay line, cross coupling is introduced and controlled easily to generate finite transmission zeros for selectivity and flat group delay. Finally, 5th-order and 6th-order filters with high selectivity and flat group delay are given as examples.
