In particular, two quarter-wave microstrip lines facing each other are aligned one on top of the other so that part of the signal flowing in one line is coupled to the other line. When pressure is applied, the distance between lines reduces, while coupling increases. That way, different pressure levels are converted into different coupling values. Two parallel-plate waveguides connect the microstrip line on the top layer to the bottom layer, so that all four ports of the directional coupler are realized on the same layer. The circuit is manufactured with stereolithography 3D printing. Selective metallization is performed embossing the desired patterns on the 3D printed dielectric and then applying silver nanoparticle ink to the protruding areas with a brush. A proof-of-concept prototype, working at 3 GHz, was manufactured and tested. The proposed prototype features a change of the transmission coefficient between the input and the coupled ports from −15.6 dB to −12.4 dB for an applied pressure of 278 kPa compared to zero pressure state, thereby proving the working principle of the circuit. The proposed transducer can be used in a harmonic transponder, and the pressure information can be retrieved from the amplitude difference of the signals at the direct and coupled ports. The obtained results open the door to a new class of pressure transducers that are based on additively-manufactured radio-frequency components, and are suitable for passive wireless sensors.","PeriodicalId":215592,"journal":{"name":"2022 52nd European Microwave Conference (EuMC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116988120","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}

Regarding the stability analysis, in 1985 he developed a frequency-domain formulation that provided unvaluable insight into the way how the perturbed system should be described and analyzed. This formulation enabled the application, for the first time, of the Nyquist criterion to circuits simulated with harmonic balance (HB). In 1994, he derived a HB formulation for phase-noise analysis, which considered both the frequency modulation, associated with the timing noise, and the frequency conversion effects; it provided a complete prediction of the noisy oscillator spectrum at small and large offset frequencies from the carrier. Departing from these relevant contributions, more recent advances in the two topics will be described.","PeriodicalId":215592,"journal":{"name":"2022 52nd European Microwave Conference (EuMC)","volume":"5 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114125780","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 goal is to provide additional information about the positioning of the applicator for a surgeon before the intervention starts. To achieve this, a tailored calibration procedure for microwave dielectrometry is suggested, that requires the measurement of healthy tissue of the patient as one of three references. With the proposed procedure tumor detection is supposed to be optimized in terms of sensitivity taken into account the influence of patient specific tissue properties. The other two reference measurements for calibration are done with the applicator in air and in a water bath. Hence, this approach prospects that there is no large effort to personalize the dielectric sensing for a specific patient.","PeriodicalId":215592,"journal":{"name":"2022 52nd European Microwave Conference (EuMC)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125626545","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 effect a High Electron Mobility Transistors (HEMTs) knee voltage can have on achievable drain efficiency of Class J and Continuous Inverse Class F (CCF−1) is presented. Drain efficiency can be as low as 60% for Class J and 82% for CCF−1 when considering a real device such as a GaN HEMT. This paper therefore proposes the combination of Class J and CCF−1 modes for achieving high average efficiency across the bandwidth of operation of a PA. This combination of modes is verified with the design and manufacture of a 10W PA using a Wolfspeed CGH40010F GaN HEMT. The realised PA achieves a power output of between 39.5 – 42.2dBm with a drain efficiency between 68.8–82.9 %.
