摘要
This paper presents the design of Legendre group of lowpass filters using DGS for microwave application. Legendre Polynomial Product (LPP)-312 and 213 filters have reduced group delay variation in the passband, achieved sharper cut-off and wider impedance matching BW. The measured selectivity of 5-pole Legendre, LPP-312 and LPP-213 lowpass filters are 28.3 dB/GHz, 18.8 dB/GHz and 18.2 dB/GHz. Their 20dB rejection BW (RBW) are 6.0 GHz, 7.7GHz and 7.9 GHz respectively. The LPP-213 has better 15dB matching BW (94%) and more 20dB rejection BW(7.3GHz).
