The module contains two millimeter-wave monolithic integrated circuits, an upconverter and an amplifier chip in a 50 nm InGaAs-based metamorphic high electron mobility transistor technology. The upconverter chip has the capability of controlling the local oscillator isolation behavior over frequency with voltage-controlled Lange couplers, which create the differential quadrature I and Q. Regarding the ITU recommendation and ETSI standard for fixed-point terrestrial wireless links, the transmitter module can be optimized either for the downlink or the uplink band. An LO isolation of above 40 dB could be achieved with tuning at 73.5 GHz in comparison to 10 dB with the control-voltage set for 83.5 GHz. The EVM quality for complex modulated data increases from -22.5 dB to -25.2 dB for a 16QAM baseband data signal with a baudrate of 2.5GBd.","PeriodicalId":110742,"journal":{"name":"2023 IEEE Radio and Wireless Symposium (RWS)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132420885","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}

For this purpose, a complete system level simulation based on the workflow shown in Fig. 1 is carried out. The special feature of this system level design approach is that in the system simulation a complete setup with transmitting and receiving antenna, skin, fat and tumorous tissues is simulated using a 3D electromagnetic (EM) field solver. As a result, the system simulation also takes into account effects such as the near-field characteristics of the antennas that are not included in classic approaches. To investigate the influence of phase noise, a noisy LO signal is used as the input for the system simulation. This allows comparison of the results when using a perfect LO signal or a noisy LO signal. The system simulation is carried out for a FMCW radar system operating from 14 to 27 GHz and a PMCW radar system at 20 GHz. To the authors best knowledge this is the first statistical approach to model phase noise in the time domain for FMCW and PMCW radar systems.","PeriodicalId":110742,"journal":{"name":"2023 IEEE Radio and Wireless Symposium (RWS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133706999","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 magnetic control antenna coupler consists of a reed switch and radiator coupler. Controlled by a magnet, the reed switch has two states, on and off, and thus the antenna coupler has two states with different resonant frequencies and coupling performance. Coupling this coupler with RFID commercial tag results in the tag working state change. This is mainly reflected in RSS and phase results by the reader. This RFID sensing method uses magnets for wireless passive sensing of various actions. It does not require the design of a specific tag, and sensing functions can be achieved by using commercial tags. Two applications based on the method are shown to reflect its convenience and efficiency. It has good application potential in health assistance, the Internet of things and smart home.","PeriodicalId":110742,"journal":{"name":"2023 IEEE Radio and Wireless Symposium (RWS)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116677270","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}

High gain and low noise figure (NF) is achieved with a 3-stage common-source structure with inductive degeneration. Interstage passive high-pass and low-pass filters improve the stability with minimal degradation of the NF. Two LNAs are placed side-by-side in a single 3mm × 3mm die for integration into a correlation radiometer circuit.

A wideband balun is used for converting the single-ended injection signal to differential injected signals. Divide-by-4 is attained using dual linear mixer technique, i.e., dual divide-by-2. The first quadrature-phase (I/Q-phase) divide-by-2 is performed by the direct-injection to the differential switch transistors. The second divide-by-2 is carried out by the tail-injection to the I/Q-phase cross-connected four-stage differential ring oscillators. Due to the inherent divide-by-4 feature of the dual linear mixer, strong differential-I/Q divide-by-4 outputs are obtained. In addition to the first-stage frequency divider of a K-band phase-locked loop, the circuit can also be used to provide the required differential-I/Q LO signals (for I/Q modulation/demodulation) of a 28 GHz 5G transceiver. The ILFD4 consumes 7.2 mW and achieves locking range of 48.4% (12.2-20 GHz) and figure-of-merit (FOM) of 6.72 mW−1, one of the best results ever reported for CMOS ILFD4s with similar operation frequency.","PeriodicalId":110742,"journal":{"name":"2023 IEEE Radio and Wireless Symposium (RWS)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123002065","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}

For a given power ratio of the two signals, the achievable information rate of embedded data is analyzed, and the trade-off relationship among the two information rates and power ratio is confirmed by the computer simulation in terms of the coded bit error rate (BER) performance.
