A novel design is presented based on distributed MEMS transmission line technique, which employs switchable transmission line stubs to minimize the unwanted loading in different states. The proposed design is capable of utilizing a minimum number of switches to achieve a delay resolution of 32 picoseconds and a return loss of more than 15 dB for all states over a bandwidth of 100 MHz around 2.45 GHz. A switch module, MM-3100 by Menlo Microsystems composed of 6 MEMS switches integrated on a single-chip, is used to realize the proposed design. Simulation and measurements are in close agreement and their negligible discrepancies are justified. The proposed design promises to be useful in applications such as analog RF interference cancelation, analog signal processing (ASP), and antenna beamforming.","PeriodicalId":6481,"journal":{"name":"2017 IEEE MTT-S International Microwave Symposium (IMS)","volume":"61 1","pages":"1300-1302"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87735656","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}

Especially in GHz applications, such as 4G/5G mobile communications, a low error-vector magnitude is required, which is strongly influenced by the phase noise of the reference oscillator. This paper reports the results of the design, simulation, and measurement of a MEMS oscillator with very low phase noise. Therefore, it is suitable for use as reference oscillator operating at high frequencies in RF receiver systems. While the MEMS device is a plate-shaped contour-mode resonator in an aluminium-nitride-on-silicon technology, the active part of the oscillator is designed and fabricated in a 180 nm CMOS technology. By adding the parasitic effects of the assembly, taken from measurements of the submodules, the results from system simulation and measurement show good agreement, i.e. only 3 dB deviation in the noise floor of −142 dBc/Hz. The phase-noise level of the oscillator at an offset of 1kHz from the operating frequency of 256 MHz is −112 dBc/Hz, among the lowest values reported for MEMS-based oscillators at this high frequency.","PeriodicalId":6481,"journal":{"name":"2017 IEEE MTT-S International Microwave Symposium (IMS)","volume":"13 1","pages":"1303-1306"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82677342","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}

To improve this, we examine shrinking the THz wave spot size by integrating a detector with a hyper-hemispherical silicon lens. We report the 6-fold enhancement of the coupling efficiency by the silicon lens integration. Also, we show that the dependence of the detector module responsivity on incident THz wave frequency is given by the product of the internal responsivity of ADGG-HEMTs and the light coupling efficiency owing to the silicon lens.","PeriodicalId":6481,"journal":{"name":"2017 IEEE MTT-S International Microwave Symposium (IMS)","volume":"74 1","pages":"578-581"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83745410","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}
