CHO cells were concurrently incubated in media with and without glucose and glutamine. After 54 hours, cells were identified as viable and non-viable by trypan-blue exclusion test. The DEP response of single viable and non-viable cells were measured at frequencies over a 100 kHz-300 MHz frequency range using a wide-band DEP cytometer. The results reveal that the induced stress is accompanied by decrease in the cell membrane capacitance, decline in the ion content of cytoplasm, and decrease in the high frequency Clausius-Mossotti factor associated with cytoplasm permittivity.","PeriodicalId":6481,"journal":{"name":"2017 IEEE MTT-S International Microwave Symposium (IMS)","volume":"35 1","pages":"872-875"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77373061","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}

This DPA puts out 85W Pavg and 500W peak power at the Doherty 50-Ω output, with relatively flat 4549% average efficiency across 20% frequency bandwidth, when tested using 10dB PAR WCDMA signal. The DPA offers very good linearized DPD performance in band-1 for 1×20MHz and 3z20MHz LTE signals. To the knowledge of the authors, this is a first 2-Way DPA demonstration exhibiting such wideband high power levels, over 20% bandwidth, while maintaining good efficiency and relatively good linearized performance, with less complexity.","PeriodicalId":6481,"journal":{"name":"2017 IEEE MTT-S International Microwave Symposium (IMS)","volume":"19 1","pages":"1106-1109"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80398092","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}

Within the architecture, a one-tap analog cancelling circuit is first deployed to reconstruct and cancel the strong leakage self interference (SI) to yield a residual multi-path SI of reduced dynamic range. Subsequently, an auxiliary transmit chain is deployed to particularly reconstruct and cancel the residual multi-path SI components, to further improve the overall analog cancellation performance. Experimental results have validated the superior analog cancellation performance of this architecture on wide-band long-term evolution signals.","PeriodicalId":6481,"journal":{"name":"2017 IEEE MTT-S International Microwave Symposium (IMS)","volume":"114 1","pages":"1169-1172"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79332203","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}

These features are traditionally offered by dual mode filters. During the last decades, several designs have been implemented using waveguides with different cross-sections such as rectangular, circular or elliptical, where different coupling structures have been proposed. In this paper, a novel implementation using the equilateral triangular waveguide is introduced. One main advantage of this proposed structure is its wide spurious-free window in comparison with other dual-mode implementations. Moreover, the modes of the equilateral triangular waveguide are also analytic, and the full-wave design can be carried out with the efficient Mode-Matching technique. Thus, this type of implementation proves to be as suitable as other structures with analytical waveguides (i.e. the classic rectangular structures), having at the same time a wide spurious-free window response.","PeriodicalId":6481,"journal":{"name":"2017 IEEE MTT-S International Microwave Symposium (IMS)","volume":"37 1","pages":"1192-1195"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81215007","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 measurement setup presents unique characterization possibilities since it has two ports at low/baseband frequencies and two ports at RF, making it ideal for characterization of frequency-translating devices such as mixers. A commercial upconverting IQ-mixer is studied, with the I and Q input signals residing at incommensurate frequency grids, enabling separation of the nonlinear distortion generated in the I and Q branches. Frequency-domain and time-domain measurements reveal imbalances between the I and Q branches in terms of conversion gain and nonlinear distortion. It is also shown for the same mixer that operating the I and Q branches concurrently has limited influence on both conversion gain and nonlinear distortion, compared to non-concurrent operation.","PeriodicalId":6481,"journal":{"name":"2017 IEEE MTT-S International Microwave Symposium (IMS)","volume":"21 1","pages":"1433-1436"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72907166","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}
