Abstract

This paper presents the simulation and comparison of effect of two different coupling feed type in parallel coupled line filter. The filter is designed and optimized for 60GHz center frequency with a fractional bandwidth of 10GHz.Keysight ADS software is used to simulate and compare the performance of different coupled filters in terms of performance and chip size. A fifth order parallel coupled line filter with coupling type transformer input and tapped line transformer input has been compared. A 5th order hairpin type band pass filter is also simulated to compare the effect of coupling making the design compact. 127um thick alumina substrate is used to realize the filters.
