Initial design procedure of microstrip interdigital filter with tapped-line
摘要
Abstract
There are many initial design methods for microstrip interdigital filter with tapped-line but the design methods are not complate,concise and accurate enough,so a set of initial design flow with completeness and conciseness is given.The de-sign steps are as follows:index "standardization",determine the low-pass prototype filter,determine the order of the filter,de-termine the normalized conductance value,design tapped line length and width,design resonator width,design non-input/output resonator length,design adjacent resonator spacing,design input/output resonator length and tapped line position,integral mod-eling and simulation of interdigital filter.Finally,taking the initial design of Ka-band filter as an example,the initial design re-sults show that the center frequency is about 30.19 GHz,the passband range is slightly larger than 29.40-31.00 GHz,the maxi-mum insertion loss is 4.21 dB,the minimum return loss is 9.35 dB,the stopband rejection of 27.00 GHz and 33.40 GHz is more than 30.00 dB,which basically meet the design indexes,only a little optimization is needed to fully meet the design indexes,and the feasibility and high accuracy of the design flow are verified.关键词
