The equivalent series capacitance of the CRLH TLs, constructed by using microstrip interdigital capacitors, is loaded with microfluidic channels, and exposed to the material under test (MUT) to act as the sensing element. Due to the nonlinear dispersion relation of the artificial TLs with respect to the sensing capacitor, higher sensitivity over a frequency band as wide as 4-8 GHz is achieved, compared to the previously-reported resonator- or capacitor-based sensors. The final fabricated system prototype is 4 cm×8 cm. Moreover, a calibration method is presented based on measurement results, which shows an rms error less than ~1.5% for liquid-chemical permittivity detection.

By designing the SPA-D at device level, the bandwidth limitation due to device parasitics and the frequency dependence of peaking output impedance can be mitigated. External capacitors are used in combination with the device output capacitances and package parasitics to form very short transmission lines (TL) having characteristic impedances of the corresponding device optimum impedances. In this way, the fractional bandwidth (FB) of SPA-D can be extended up to 60%. The high power SPA-D demonstrator exhibits measured drain efficiency of 45%-67.5% at 8 - 10 dB power back-off (BO) and 54%-79% at peak power of ≥ 100 W over 460 MHz-830 MHz (~ 57% FB). At 710 MHz, a measured power added efficiency (PAE) of 70 % and 62.5 %are achieved at 50.5 dBm output power and 8 dB BO, respectively.

Several concepts have been proposed that obtain an estimate with high accuracy. However, these concepts require a continuous wave input signal during measurement. In this work we aim to estimate the PN power spectrum of a frequency modulated continuous wave (FMCW) radar transceiver simultaneously with its normal operation. The novel method obtains the PN power spectrum across the whole FMCW chirp bandwidth. It utilizes an artificial on-chip target (OCT), which is to be incorporated into an existing monolithic microwave integrated circuit (MMIC). Two concepts to obtain the PN power spectrum are presented and validated with measurements that deliver accurate estimates within the frequency range of interest.","PeriodicalId":6554,"journal":{"name":"2016 IEEE MTT-S International Microwave Symposium (IMS)","volume":"1 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77379291","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 is known that in general, a transversal array coupling topology that offers a generalized Chebyshev function response is hard to design in a physical structure, owing to simultaneous parallel excitation of resonators. To overcome such a drawback, this paper introduces a fully canonical Cul-de-Sac coupling that can be obtained with mathematical transformation from a transversal array coupling. The proposed filter structure for the Cul-de-Sac coupling has two resonator blocks, which are excited by two-branch lines: one is a block of even-mode half-wavelength resonators arranged in parallel to input/output lines, and the other is a block of odd-mode ones. The filter can be easily designed by coupling coefficients between two adjacent resonators without any cross couplings. The effectiveness of the proposed filter is verified with synthesis, design, and test of a 2-GHz fourth-order microstrip filter with four TZs.","PeriodicalId":6554,"journal":{"name":"2016 IEEE MTT-S International Microwave Symposium (IMS)","volume":"21 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79005875","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}
