Especially low-phase noise oscillators, which are required at nearly all frequencies in multi-band RF modules, often consist of components using different technologies, e.g., micro-electromechanical systems (MEMS) resonators and microelectronic circuits, usually with one resonator per output frequency. This paper presents the compact implementation of a multi-frequency MEMS oscillator on a silicon-ceramic composite substrate, tailored to the construction of multi-physical RF modules. MEMS devices and microelectronic circuits are fabricated and assembled on opposite sides of the same substrate, in order to nearly halve the substrate area used. The benefits of integrated circuits for switching, frequency doubling, and dividing increase the scope of functions by keeping the module size nearly constant. This results in a highly integrated oscillator module with optimised phase-noise performance.","PeriodicalId":6720,"journal":{"name":"2019 IEEE MTT-S International Microwave Symposium (IMS)","volume":"36 1","pages":"782-785"},"PeriodicalIF":0.0,"publicationDate":"2019-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78849765","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}

First, a phase calibration of the radio and intermediate frequency path transfer function compensates for distance dependent effects. The unambiguous frequency of the target is used for range cell estimation and the ambiguous but highly accurate and precise target phase is combined with this range cell information.To demonstrate the capabilities of the proposed signal processing chain, distance measurements using an 80 GHz wideband FMCW radar sensor with a movable target and a maximum measurement range of up to 5 m have been carried out. The target is mounted on a precision linear track and the position is laser interferometer referenced. For free space measurements with a target in about 1.2 to 5 m distance, the unambiguous single measurement accuracy has been improved from about ±400 µm to ±8 µm. A potential application of a radar system using this algorithm is the online measurement of machine tools.","PeriodicalId":6720,"journal":{"name":"2019 IEEE MTT-S International Microwave Symposium (IMS)","volume":"25 1","pages":"552-555"},"PeriodicalIF":0.0,"publicationDate":"2019-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79647317","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 proposed multi-band BPF concept is based on multi-resonant cells that are incorporated within the two transversal paths of a doublet. It is shown that by solely reconfiguring the resonant frequencies of its constituent resonators, multiple quasi-elliptic-type passbands can be created and controlled in terms of: i) center frequency, ii) bandwidth, and iii) number through their intrinsic RF switching and/or merging. In addition, the proposed filter concept allows for the realization of i) an all-reject state and ii) a single-band BPF state with >5.1:1 BW tuning. The theoretical design principles of the multi-band BPF approach are presented by means of coupling routing diagrams and synthesized examples. For proof-of-concept demonstration purposes, a tri-band BPF microstrip prototype was designed, manufactured, and measured.","PeriodicalId":6720,"journal":{"name":"2019 IEEE MTT-S International Microwave Symposium (IMS)","volume":"87 1","pages":"91-94"},"PeriodicalIF":0.0,"publicationDate":"2019-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77572222","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 complex frequency response of the oscilloscope’s sampler is derived in the frequency domain as the ratio of the oscilloscope signal spectrum to the calibrated LSNA signal spectrum.

By adopting a long inductive transverse slot in each unit cell while keeping a small period length, the sensitivity of effective phase constant (i.e. the slope of effective phase constant versus frequency) of the unit cell can be increased significantly, thereby resulting in a quasi-uniform leaky-wave antenna with a fast beam-scanning property. The working principle is elaborated with an equivalent circuit model of the unit cell, and both of circuit-based and full-wave simulations are conducted to verify the design concept. To do the demonstration, a limited frequency band from 34 to 36 GHz (5.7%) has been designated specifically to implement the proposed leaky-wave antenna. Furthermore, a taper design with -25 dB Taylor distribution is carried out for the antenna to achieve a low sidelobe radiation. A prototype is then fabricated and tested. Experimental results show that the beam can be scanned from 17o to 58o with low sidelobe levels over such a narrow bandwidth. The simulated and measured results are in a good agreement.","PeriodicalId":6720,"journal":{"name":"2019 IEEE MTT-S International Microwave Symposium (IMS)","volume":"39 1","pages":"885-888"},"PeriodicalIF":0.0,"publicationDate":"2019-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77518901","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}
