However, manual settings of the attenuators are prone to human errors, and thus the repeatability of each measurement need be studied case-basis. This paper studies calibration accuracy of extenders, and the repeatability and reproducibility of a waveguide attenuator operating at 220 to 330 GHz. The average calibration variation of S21 with three operators and three repeated calibrations over frequencies was -0.009 dB and 0.072° for directly connected frequency extenders. The measured setting accuracy of any waveguide setting was 1.4 dB (±2σ) over 15 dB range. The primary source of measured variation in S11 and S21 in variable attenuator setting measurements was due to repetition of measurements since there was no significant statistical difference between three operators.","PeriodicalId":266876,"journal":{"name":"2022 98th ARFTG Microwave Measurement Conference (ARFTG)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126063468","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}

Then, using a pre-distorted waveform created by spectral DPD, a generic memory-polynomial DPD model is identified. This model is then applied to the original waveform to generate a pre-distorted waveform, providing a linearized test signal.

However, a physical circuit-level SNN implementation and feasibility of its integration with millimeter-wave circuit blocks towards a system on chip (SoC) has not been reported yet A voltage-controlled oscillator (VCO) is the core element of FMCW radar transceivers and one of the most sensitive blocks in the system. This work evaluates empirically for the first time the potential interferences during concurrent operation of an SNN and a 77 GHz VCO integrated on the same chip. The coupling effects are investigated experimentally in time- and frequency-domain, particularly by phase noise measurements. The VCO exhibits a low phase noise of -100.25 dBc/Hz at an offset frequency of 1MHz from 77 GHz carrier, while the SNN activity is turned off. By an intentional triggering of the SNN, a significant impact on VCO is observed and the phase noise is deteriorated up to as much as -89.75 dBc/Hz at the same offset frequency. The circuit blocks are implemented on a testchip in a 130 nm BiCMOS technology.","PeriodicalId":266876,"journal":{"name":"2022 98th ARFTG Microwave Measurement Conference (ARFTG)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124270453","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 satisfy the demand for mobile data transfer, the use of mobile networks has to be more effective and more frequency bandwidth has to be allocated. In the already heavily used sub-6-GHz spectrum, no additional bandwidth is available. Therefore, the mobile network has to operate in the millimeter wave regime to provide a high data rate for the user. In this challenging part of the spectrum, the new antenna systems must be characterized to comply with 3GPP rules. This paper addresses a part of the metrological challenges, which is the measuring of the beam steer execution time.","PeriodicalId":266876,"journal":{"name":"2022 98th ARFTG Microwave Measurement Conference (ARFTG)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127919088","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 most prominent issue in implementing MIMO full-duplex system is both hardware nonlinearities and signal interference. The proposed approach is utilized to significantly cope with self-interference due to other channels in the same chip of the MIMO system. Specifically, we offer a two-step procedure to estimate the channel between the desired output and signal of interest and the channel with desired output and an interfering signal. In the next step, perform self-interference cancellation. Numerical evaluation of the technique shows that the bit-error rate was reduced from an order of 10-1 to an order of 10-4, and the error vector magnitude was reduced from -6dB to a value of-35 dB.","PeriodicalId":266876,"journal":{"name":"2022 98th ARFTG Microwave Measurement Conference (ARFTG)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130271257","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}
