AbstractThis article proposes a bandpass filter with three controllable transmission zeros (TZs) using three inductive-coupled stub-loaded resonators (SLRs). Different from other works, the proposed SLR can create one transmission pole and one TZ. With the TZs above the passband, high stopband rejection level is achieved. Moreover, the K-inverters are realized by short-circuit stubs between two adjacent SLRs. A general synthesis method for this kind of filter is described. For verification, a filter centered at 2.44 GHz with 0.18 GHz bandwidth is designed. The measured results show that the filter has three TZs at 3.1, 3.9, and 5 GHz. With those TZs, the filter's stopband rejection level is greatly improved.

General Method

A new general synthesis method for hypervalent diorganoantimony(iii) fluorides with pendant arm ligands is ​ based on treatment with [Bu4N]F·3H2O of ​ cationic species e.g. [{2-(2′,6′-iPr2C6H3NCH)C6H4}2Sb]+[PF6]− or [{2-(Me2NCH2)C6H4}PhSb]+[SbF6]−.
