Poly-Resonator Lowpass Filter for 26th Order Harmonic Suppression
By
Progress In Electromagnetics Research M, Vol. 109, 179-189, 2022
Abstract
In this brief, an ultra-vast stopband lowpass filter with miniaturized circuit size for 26th harmonic suppression using poly-resonators and an inclined stepped-impedance transmission line (ISTL) is developed. The poly-resonators such as radial stub resonator and resonator modules constitute the significant part of the filter, and the discontinuity in the inclined angle of the ISTL is balanced by 75% chamfering. The coupling with ISTL has influence over the stopband behavior, and the equivalent circuit for the first transmission zero is analysed. The normalised circuit size is reduced to 16.6%, and additional frequency rejection is achieved using resonator modules RM1 and RM2. The relative stopband width of 185.4% is attained with a 3 dB cut-off frequency of 1.51 GHz. L band communication applications having circuit area limitations can make use of the Poly-resonator ISTL filter for achieving high-frequency noise rejection.
