The amplifiers are designed to first validate the passive and active millimeter-wave models and then study the MOS reliability at 60 GHz. In this way, the PAs design takes electromigration constraints at 125°C into account which implies limitations on MOS width and thus on the circuits performances. The PAs operate from a 1.2 V supply voltage. A power gain of 7.8 dB and 4.5 dB, an OCP1dB of 9 dBm and 6 dBm with 12.2% and 12.3% PAE and a saturated output power of 12 dBm and 9 dBm at 60 GHz are measured respectively for the 2 stages and the 1 stage amplifiers. Excellent agreement between measurement and simulation results at small and large signals is observed.","PeriodicalId":112402,"journal":{"name":"2010 IEEE 11th Annual Wireless and Microwave Technology Conference (WAMICON)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117036751","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 detector contains only one active component, a diode-connected NPN bipolar transistor. The detector's two major advantages, simple circuit structure and variable measuring configurations, make it a good candidate for on-chip applications, and specifically convenient for Six-Port Reflectometer (SPR). To demonstrate its powerful functionality over a wide band, one of its several different measuring configurations is fabricated as a stand-alone circuit in the 0.13-µm IBM BiCMOS-8HP technology. The simulation results show that the detector can work up to 80 GHz, and the measurement results verify its functionality up to 67 GHz due to test equipment limitations. The closed-form formulas of the developed detector are also given.","PeriodicalId":112402,"journal":{"name":"2010 IEEE 11th Annual Wireless and Microwave Technology Conference (WAMICON)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125549991","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}

Distinct from traditional notch implementation, the proposed method uses the additional metal lines with half waveguide length embedded in defected ground structure to produce additional notch band behavior based on the DGS bandpass behavior. Furthermore, the equivalent circuit model of the proposed UWB BPF with notch implementation is established for explaining the circuit behaviors more explicitly. In this way, the proposed circuit has a very small size, only amounting to 0.41 by 0.22 guided wavelength at the center frequency of 6.85 GHz. The experimental filter has a notchband frequency of 5.5 GHz, with two observable attenuation poles at 1.65 and 11.36 GHz, respectively. The measured BPF insertion loss is less than 1.0 dB throughout the passband of 3.1 to 10.6 GHz, and the variation of group delay is less than 0.2 ns in this band, except for the notched band.","PeriodicalId":112402,"journal":{"name":"2010 IEEE 11th Annual Wireless and Microwave Technology Conference (WAMICON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131744702","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 switches are of proven design and reliability, except some switches have a gap in their stationary electrodes. This novel feature has negligible effect on electromechanical operation but provides another degree of freedom for simultaneous optimization of phase shift and impedance match. The design principle is validated through specially designed thin-film test structures. The results suggest that the present design is applicable to phase shifters of different sizes and resolutions with high performance, yield and reliability, but low cost and power consumption.","PeriodicalId":112402,"journal":{"name":"2010 IEEE 11th Annual Wireless and Microwave Technology Conference (WAMICON)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114978877","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}
