In G-band we have developed an amplifier with 8.7 dB small-signal gain at 149 GHz, and when two such amplifiers were placed in series, large signal power measurements gave 18.2 dBm of output RF power and 10 dB gain at 147 GHz.

Frequency selectivity is increased by introducing two transmission zeros via cross coupled resonators. Tunability is achieved by using thin film barium strontium titanate (BST) varactors. The structure is applicable in future seamless and band less cognitive radio systems. The center frequency is adjusted by varactors which are loading the open-loop resonators, while coupling varactors between the resonators enable the control of bandwidth. The proposed filter structure is designed for a center frequency range from 1.5 GHz to 1.75 GHz with a constant bandwidth of 100 MHz and a tunable bandwidth between 70 MHz and 180 MHz at a fixed center frequency of 1.625 GHz. The functionality of the design is experimentally validated.","PeriodicalId":170594,"journal":{"name":"2018 IEEE Radio and Wireless Symposium (RWS)","volume":"3 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":"128983877","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}

In 5G, concurrent operation of multiple RF bands is considered including new SHF bands over wide frequency range. This paper presents an SHF concurrent dual-band bandpass filter (BPF) consisting of a low-SHF three-bit/eight frequencies (3.5–5GHz) reconfigurable BPF and a high-SHF (8.5GHz) BPF. It employs a direct parallel-connected configuration of the two BPFs without divider/combiner. The prototype BPF can switch low-SHF passbands without affecting the high-SHF BPF performance. The low insertion losses from 1.6 to 2.1 dB are achieved for low-SHF frequencies, whereas that for high-SHF BPF is 2.3 dB.","PeriodicalId":170594,"journal":{"name":"2018 IEEE Radio and Wireless Symposium (RWS)","volume":"160 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":"114112506","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}

Considering this, we study a single-carrier scheme with frequency domain equalization (SC-FDE) and a multiple-input multiple-output (MIMO) scheme. The SC-FDE could achieve a smaller peak-to-average power ratio, resulting in a smaller power amplifier.

To enhance the operation frequency range of the voltage-controlled oscillator (VCO) in the PLL, reversely tunable LC source degeneration technique is adopted. To improve the frequency locking range of the divide-by-3 injection-locked frequency divider (ILFD) in the PLL, a parallel inductor is used to parallel resonate the parasitic capacitance of the cross-coupled transistors. In addition, a phase and frequency detector (PFD) with enhanced D flip flops is used to effectively reduce the dead zone. The PLL consumes only 49.6 mW and exhibits an operation range of 2.4 GHz and reference sidebands of less than −56 dBc. The chip area of the PLL is 0.656 mm2 excluding the test pads.","PeriodicalId":170594,"journal":{"name":"2018 IEEE Radio and Wireless Symposium (RWS)","volume":"30 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":"125239487","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 RF filter concept consists of in-series-cascaded transversal signal-interference filtering cells with an embedded tunable quasi-absorptive-type notch in the transmission range of each of them. Each of these cells is made up of three signal-propagation paths in which one of them is reused by both filtering functionalities. This leads to smaller footprint as opposed to conventional solutions based on in-series cascades of separate filtering units. Furthermore, the in-band tunable notches can be spectrally merged so that the number of active rejection bands in the passband is dynamically controlled. For experimental-demonstration purposes, a 2-GHz two-stage microstrip prototype with two independently-tunable quasi-absorptive-type notches is developed and characterized.","PeriodicalId":170594,"journal":{"name":"2018 IEEE Radio and Wireless Symposium (RWS)","volume":"20 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":"133691444","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}
