The interference is down-converted to baseband, low-pass filtered, then up-converted and subtracted from the input. Harmonic response in the active canceler is eliminated by using harmonic rejection mixers (HRMs). Furthermore, by configuring the HRMs to provide frequency translation while using the LO fundamental or its harmonics, the span required of the frequency synthesizer for driving the HRMs is reduced. Implemented in a 65 nm process, the proposed technique shows 8-13 dB improvement in blocker 1-dB compression.","PeriodicalId":121490,"journal":{"name":"2015 IEEE Radio Frequency Integrated Circuits Symposium (RFIC)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132171643","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 low-cost TRX consists of a low-IF receiver with 180 kHz signal bandwidth, a digital polar transmitter with 3.75 kHz signal bandwidth and a fractional-N frequency synthesizer. The receiver features a passive current mode mixer to improve the linearity and avoid the noise degradation due to the 1/f noise. The on-chip I/Q mismatch calibration is introduced to improve the image rejection ratio (IRR). The Inverse Class-D power amplifier (PA) is integrated into the transmitter to achieve high output power and efficiency, and the pre-distortion is exploited to realize the DPA linearization. Besides, the digital transmitter performs the power output by digitally controlling the DPA unit array. In order to compensate for PVT variations, the DCOC, I/Q mismatch, AFC and filter frequency tuning are all integrated in the transceiver. The RX achieves 5.1dB NF, 48dB IRR and 60dB gain dynamic range with 1dB step. The DPA provides the maximum 24.2dBm output power with 28.9% PAE.

The phased array is built using independent RF, transmission-line and control circuit blocks which are stitched together to form an aggregate chip which is much larger than a standard reticle (22×22 mm2). This method allows for a wafer-scale design and can be extended to any size and any shape (rectangular, hexagonal, etc.) up to the edge of the wafer. The blocks include high-efficiency on-wafer antennas, phased-array channels with 3-bits amplitude and 5-bits phase control together with an amplifier having an output power of +3 dBm at 60 GHz. Also, a highly redundant RF distribution network is synthesized from several stitched blocks for improved yield, and the control blocks have redundant SPI control and power strips, also for improved yield. The 256-element array results in a half-power beamwidth of 6° in the E- and H-planes, a directivity of 29 dB, and scans to +/- 55° in the E- and H-planes with near-ideal patterns and a cross-polarization level of <;-25 dB. The measured EIRP is 45 dBm at 61 GHz and with a 3-dB bandwidth from 58 to 64 GHz. To our knowledge, this is the largest single-chip phased-array ever developed and allows the construction of large-scale (1000+ elements) phased-array systems, either on a single wafer or by assembling several of these chips together.","PeriodicalId":121490,"journal":{"name":"2015 IEEE Radio Frequency Integrated Circuits Symposium (RFIC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126923037","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}
