In this paper, a simple dimensional design procedure is developed for microstrip/stripline quadruplet filters by starting with direct BP synthesis of a lumped quadruplet with inverter couplings, K14, K12, K23 and K34. K14 is the cross-coupling inverter which creates a symmetric pair of finite transmission zeros (FTZ's) if the sign of K14 is opposite of the other inverters while a complex TZ is created if K14 has the same sign as the other inverters leading to linear phase (flat delay) responses. The LC resonators are first converted into half wavelength transmission line (TL) resonators coupled by inverters. Then inverter coupled TL resonators are converted into parallel coupled lines (PCL) to form a PCL quadruplet. Two examples are presented, one with two symmetric FTZ's and one linear phase response.

On Miniaturization and Performance Improvement of Planar Wideband Bandpass Filters Without Coupled Lines Alicioglu, Bulent; Yıldırım, Nevzat (2009-10-01) Two classical approaches are compared in various respects for the design of wideband planar BPF's without parallel coupled lines, namely, BPF's designed by pole placement with contributing Unit Elements (UE) and inverter coupled resonator filters designed from LP prototypes. It is shown that the circuit obtained by direct BP synthesis is a special case of inverter coupled filter with inverters converted into single Unit Elements. It is also shown that if the inverters are converted into odd number of UE's t...
Design of Selective Linear Phase Cross-Coupled Dielectric Resonator Filters Ozturk, Onur Ozan; Oruc, Sacid; Alicioglu, Bulent; Yıldırım, Nevzat (2018-11-02) In this paper, a highly selective linear phase filter is designed and implemented in cross-coupled form using dielectric resonators in Ku band to be used as a channel filter in IMUX of a satellite receiver. Extreme delay flatness is required: 1.5 nS delay ripple over 60 % of the passband and 12 nS near the band edges. The initial design is carried out as 10 resonator symmetric cross-coupled filter with all ideal inverter couplings realizing two finite transmission zeros (FTZ) satisfying also the delay flatn...
Analysis of root displacement interpolation method for tunable allpass fractional-delay filters Hacıhabiboğlu, Hüseyin; Günel Kılıç, Banu (2007-10-01) One of the simplest ways of designing allpass fractional-delay filters with maximally fiat group delays is by using the Thiran approximation by which the filter coefficients are calculated using a closed-form equation. However, due to the number of multiplications and divisions involved, the calculation of these coefficients is a computationally costly task and is not suitable for real-time applications. The analysis of a root-displacement-based interpolation method used in allpass tunable fractional delays...
Waveguide filters with ridged and unequal width resonators Yıldırım, Nevzat; Hizal, A (2005-06-17) Analytical expressions are developed for characterization of ridged / finned waveguides for use in the design of direct coupled waveguide filters with ridged and / or unequal width resonators. The analytical expressions are used to control the harmonic passbands and higher order modes. A survey is made for comparison of responses of waveguide filters using unequal width resonators and unequal ridge resonators. it is found that ridged resonators are more effective in suppressing the spurious passbands in the...
Implementation and characterization of an absorption filter for on-chip fluorescent imaging Yıldırım, Ender; Arpali, Serap Altay (2017-04-01) Here we present fabrication and characterization of an absorption filter with superior roll-on properties and precisely tunable cut-off wavelengths for fluorescent imaging applications in lab-on-a-chip systems. The filters were fabricated by spinning dye doped photopolymer (Orasol Yellow in Norland Optical Adhesive 60) on glass substrates. The fabrication technique allowed us to precisely tune the cut-off wavelength of the filters. We showed that filters with different cut-off in the range of 386 nm-504 nm ...
