Two lumped couplers provide balanced quadrature input signaling for two doubler cells. As a result, the output signals of the two doubler cells form an inherently balanced output and a lossy output transformer can be avoided. Hence, higher output power and efficiency can be achieved. Moreover, high fundamental rejection and supply suppression with low LO leakage into other circuit blocks are further advantages. As a proof of concept, a K-band doubler is implemented in a 65 nm CMOS technology. At 0 dBm input power, the circuit delivers 4.3 dBm output power with more than 6 % PAE. The chip draws 24 mA from a 1.2 V supply and the total chip area is 0.85 × 0.55 mm2, The fundamental suppression is around 44 dBc. The concept is applicable to other technologies and frequencies as well.","PeriodicalId":248339,"journal":{"name":"2018 13th European Microwave Integrated Circuits Conference (EuMIC)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123505554","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 DDS is applicable for wireless communications and is capable of generating sinusoidal and complex waveforms up to 10 GHz. The 12-bit reduced size pipeline accumulator has been designed with a novel 6-bit phase control word unit to facilitate digital phase modulation schemes. The DDS has been successfully measured and characterized using a dedicated PCB board. Its operation has been confirmed in terms of frequency settings. The output amplitude from the DDS is lower than expected due to losses in the FR4 PCB. To our knowledge this DDS is the first attempt to employ a digital phase control and is among the fastest DDS in SiGe BiCMOS reported so far. The total power consumption is only 1.54 W. The DDS has an output frequency range from 5 MHz to 10 GHz with worst case spurious free dynamic range (SFDR) of 25 dBc with a maximum clock frequency of 20 GHz.

For a scan-phase antenna diversity with switching and phase alignment of up to three antenna paths, the integrated circuit includes RF switches, phase-alignment and signal combining as well as the frequency conversion for level detection. This is the first integrated circuit for SDARS scan-phase antenna diversity, which includes all the diversity functions except for level detection and digital signal processing. With the integrated circuit with a package size of only 9 mm by 9 mm a compact hardware demonstrator is realized. The diversity circuit is independent of the radio and offers the same interface to the radio as a conventional single antenna. In laboratory measurements characteristic values of the RF signal paths like gain and variable phase shift are determined. In addition, the new compact diversity circuit is also evaluated in a real fading scenario on a single side mirror of the test vehicle showing a significant reduction of audio mutes by the diversity system compared to single antenna reception.","PeriodicalId":248339,"journal":{"name":"2018 13th European Microwave Integrated Circuits Conference (EuMIC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126269893","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 the best of authors' knowledge, said LNA has the highest input power handling performance for the given noise figure level although transistors are not optimized for low-noise operation and input matching network is realized to compromise between noise figure and input return loss which is better than 10 dB.
