The phase-setting resolution of the chip is less than 1.0°. The phase array chip also has nine mixers for detecting the phase difference between subarrays in the chip, between channels in the subarray, and between the chip and another chip. The measured root-mean-square (RMS) output phase error and the measured RMS phase-difference detection error of the chip are both 0.7°. Using this chip with a high-precision phase-adjusting function, it is possible to realize a transmitter with a signal-to-interference ratio of over 25 dB for beam multiplexing.

The first MMIC contains a VCO at a frequency of 38 GHz for LO generation. The second MMIC encloses a complete transceiver at 76 GHz. The main goal of this work is to create a first functional version of a VCO and an one channel transceiver MMIC. With these MMICs it will be possible to build up multipurpose radar systems with a variable number of transceivers, to construct MIMO architectures. What makes this system innovative is the fact, that it is able to handle broader signals than know systems. Furthermore it isn't limited to one modulation scheme. It is possible to transmit and receive any signal form with platforms build out of these chips. The VCO MMIC achieves a tuning frequency range of 5 GHz with a center frequency of 35 GHz. It consumes 152 mW from a 3.3 V supply. The transceiver MMIC is fully functional and achieves a saturated output power of 9.5 dBm drawing 570 mW from a 3.3 V supply.","PeriodicalId":248339,"journal":{"name":"2018 13th European Microwave Integrated Circuits Conference (EuMIC)","volume":"10 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":"114233007","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 realize such a vector-sum phase shifter, one of the difficulty arises from the trade-off between a bandwidth and an insertion loss of the PPF (Poly Phase Filter) which is deployed at the first stage inside the phase shifter and generates quadrature signals from a differential signal. In order to ease the trade-off of PPF, we propose the PPF using inductor and capacitor (LC-type) power splitter implemented in front of it. Simulation results with the proposed technique show the improvement of 2.7dB in the insertion loss, without degradation of the bandwidth. As a proof of concept, vector-sum phase shifter with the proposed PPF technique was fabricated using 0.18um SiGe BiCMOS process. Measurement results showed the 3dB gain bandwidth of 64% at X-band and the RMS phase error of less than 2.1°. This broadband and highly accurate results show that the proposed PPF technique is effective to realize multi-band AP AA system in the near future.","PeriodicalId":248339,"journal":{"name":"2018 13th European Microwave Integrated Circuits Conference (EuMIC)","volume":"13 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":"132073858","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}

It achieves a peak gain of 12.5 dB and consumes a power of 3.1 mW. However, the maximum available gain (MAG) or maximum stable gain (MSG) of transistor degrades markedly because of the low supply voltage and the near maximum oscillation frequency, fmax. Thus, gain-boosting techniques must be employed to enhance the transistor's gain. An intuitive method, which involves drawing a set of circles, was presented to explain how the feedback network boosts the MAG to its highest value (Gmax). The method was employed in the design of the amplifier with a 0.35 V supply voltage.","PeriodicalId":248339,"journal":{"name":"2018 13th European Microwave Integrated Circuits Conference (EuMIC)","volume":"45 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":"130258988","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 measured temperature-dependent data between −40 to 150°C were observed of transconductance and drain current for the both devices. It was found that the variation of threshold voltage (V T) with the drain bias (V ds) has an influence on zero temperature coefficient points. Furthermore, the drain current based ZTC point arises before VT for GaN and after VT for GaAs FETs with respect to drain bias. Inconsistency are observed; most conspicuously that the temperature trends of the threshold voltage for these two device technologies are utterly contrasting. In addition, transconductance based ZTC is absent in GaN device. Furthermore, the effective mobility is estimated using an improved model for the GaN device. The results indicate a well-confined 2-DEG with high mobility as the peak value of effective mobility closely corresponds with the Hall mobility.
