This work quantifies the efficiency roll-off in multilevel PAs and proposes that pulse-width modulated (PWM) class-E PAs offer the best efficiency roll-off and dynamic range, based on the efficiency profile with power back-off (PBO). The presented technique significantly extends the PBO dynamic range of PWM PAs over prior state-of-the-art solutions. A proof of concept watt-level class-E PA is designed using a GaN HEMT and exhibits more than 65% efficiency at 15dB PBO. This design extends the dynamic range of a PWM class-E PA to more than 6dB for a 50 to 30 percent duty cycle variation, and offers an efficiency roll-off of less than 4% per dB. The proposed circuit demonstrates an increasing average drain efficiency with power back-off when reducing the PA supply voltage.","PeriodicalId":131330,"journal":{"name":"2019 IEEE Radio and Wireless Symposium (RWS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133033285","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 respiration rates of two people can be separated by the measurement of chest-wall dynamic motion, using a single-antenna 2.4 GHz continuous wave (CW) quadrature transceiver. Signal processing is used to separate the respiration rates of two targets, by observing correspondence to null and optimum points in the In-phase (I) and Quadrature (Q) channels of the transceiver. Experimental data in the single-antenna system is verified by comparison against simulated data of two moving targets wherein the reference point of one target is shifted in the simulation by introduction of a phase shift. This shows it is possible to use a non-contact measurement to distinguish between the respiration rates of two human targets by observing the I & Q frequency spectrums.","PeriodicalId":131330,"journal":{"name":"2019 IEEE Radio and Wireless Symposium (RWS)","volume":"5 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116661442","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}

Since the application of IoT is widely spread, the requirement of WSN is diversified. Physical wireless parameter conversion sensor networks (PhyC-SN) can support the real time data collection and the affordability of collecting the sensing results from a lot of sensors. However, PhyC-SN cannot detect each sensing results, separately. The data tracking technique with using time continuity as tracking criterion is available for data separation but the error tracking occurs if sensing results are close. This paper proposes the transmission technique with the prediction of sensing results for the data separation of PhyC-SN. From the predicted sensing results, FC can estimate the occurrence of error tracking and switch access protocol from simultaneous access to time division access for avoiding error tracking. From the computer simulation, the proposed transmission technique achieves the more highly accurate data collection than time division multiple access and conventional PhyC-SN.","PeriodicalId":131330,"journal":{"name":"2019 IEEE Radio and Wireless Symposium (RWS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121550596","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}

It consists of an antenna array, an expansion board, an evaluation board with microcontroller and Wi-Fi chip for signal generation and one board for power division and beam steering. Moreover, the problem of the latency and inaccuracy of beam steering by received signal strength will be treated and optimization steps in the algorithm will be presented.

The second ILFD3 (ILFD32) uses a tail transistor to amplify the injection signal, which then injects the source terminals of the lower CCTs. Due to the strong second harmonic signal (2finj) at the source terminals of the upper CCTs, there are notable locked fundamental signals (finj) at the drain terminals of the upper CCTs.
