In the proposed system, two BSs provide different signals: one transmits a modulated signal with the bandwidth and the other transmits a continuous wave (CW) signal at a different frequency. The CW signal is utilized as a local signal to detect the received modulated signal at the MSs. An advantage of this scheme is that the radio frequency frontend configuration of the MS is simplified because it is not necessary to implement a local oscillator with a high frequency and high purity. However, since the CW signal is received with the modulated signal at the MS, its receiver must appropriately extract the CW signal from the received signals. Therefore, this paper also presents a novel receiver that has a CW extraction function. To confirm the feasibility of the proposals, a transmission system including the proposed receiver is constructed and tested at around 3.9 GHz. Measurement results show that an adequate quality level with the EVM degradation of approximately 0.1% is achieved using the extracted CW signal from the received signals.","PeriodicalId":273434,"journal":{"name":"2016 IEEE International Symposium on Radio-Frequency Integration Technology (RFIT)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115470546","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 four transceiver channels are synchronized by an I/Q standing wave oscillator (SWO). Their signal phases are shifted by hybrid analog IF and LO phase interpolators, and can be controlled digitally and independently. The SWO further composes an on-chip PLL, and is locked to a 1.09 GHz off-chip global reference to scale to a large array at board level. Each receiver channel achieves 66 dB maximum conversion gain and 4.4 dB minimum noise figure. Each transmitter channel achieves 18 dBm maximum output power. The chip is mounted on a high-frequency laminate, inside which embedded cables connect its RF pads to Vivaldi antennas also inside the same PCB. With the PCB, each channel achieves 360° phase shifting capability under a maximum calibrated 3.7° phase errors. The PCB module presents successful beam steering with 23° measured four-channel 3-dB beamwidth.
