Compared to a single-ended architecture, the differential one drastically reduces even-order intermodulation products, improves insertion loss, extends the bandwidth, and significantly decreases the required modulation frequency.

Direct IQ modulation/demodulation blocks, baseband analog circuitries and frequency synthesizer are commonly used parts for both of low/high frequency operations where one-stage frequency up/down conversions are exploited for high frequency bands.

In order get a compact configuration the extracted-pole in-line configuration with non-resonating nodes (NRN) is adopted. First the synthesis of a low-pass prototype is carried out and the generalized coupling coefficients together with the resonant frequencies are computed as outlined in the literature. A suitable de-normalized equivalent circuit is then derived with reference to the specific filter configuration here considered. Finally, the dimensioning of the structure is carried out suitably exploiting full wave simulations for imposing the parameters of the equivalent circuit obtained from the synthesis to the physical structure. The proposed methodology has been validated by the design and fabrication of two high selectivity filters to connect in cascade for realizing a band pass filter easily tunable both in center frequency and bandwidth.","PeriodicalId":6481,"journal":{"name":"2017 IEEE MTT-S International Microwave Symposium (IMS)","volume":"9 1","pages":"748-751"},"PeriodicalIF":0.0,"publicationDate":"2017-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84197282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The concept using a metal mesh box with a shelf is demonstrated. First, it is confirmed that the power transfer frequency can be confined inside the box by S-parameters from port 1 to each received port and the electric field standing wave in the box.
