This paper outlines a concise method for high frequency distributed filter design based on predistortion of the filter transfer function by appropriate loss/or gain factor. The approach enables the designer to realize all the filter specifications without resorting to the traditional circuit optimization and tuning (tweaking). To appreciate the benefits derivable from predistorting filter circuits, this work begins by demonstrating the defects on filter responses due to lossy lumped circuit elements. The predistortion of the lossy circuit is then implemented to show the usefulness of the predistortion technique. As an extension of the concept, the predistortion of distributed bandpass filter is implemented to correct the shift in the centre frequency of a microstrip-line filter operating at 5GHz centre frequency.
