Available in PDF, EPUB and Kindle. Book excerpt: Wireless technology is redefining life and fueling socio-economic growth globally due to a dramatic increase in the use of mobile devices and growing number of data-hungry applications. However, the very success of wireless technology is leading to a severe spectrum crunch. Ongoing advances in the device and integrated circuit technology are enabling low-cost phased-array radios that can operate at millimeter-wave (mm-wave) bands as they provide very large bandwidth to meet data-rate demands. Future single-chip solution will require wideband circuits to support multiple mm-wave bands for a higher aggregate data-rate. In addition, low-power consumption and a compact circuit size are desired for battery-limited mobile radios as the power consumption and area of phased-array increases with the number of array elements.

This book was released on 2017 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation has been mainly focused on reconfigurable mm-wave integrated circuits for next generation wireless communication systems (namely, 5G). One of the major approaches to making 5G a reality is the use of high-frequency signals in the millimeter-wave (mm-wave) frequency band to facilitate access to more bandwidth. This can deliver faster and more reliable data to more users. This dissertation contributes to making wideband, bidirectional, and scalable RFICs for high data rate point-to-point communications over large distances in mm-wave bands, particularly the E-band (71-76 GHz, 81-86 GHz). The E-band is a licensed band in the US, with 10 GHz of bandwidth allocated to low-cost, high-capacity, and point-to-point communication. For backhaul base-stations or air-to-ground communication, a scalable and large-element phased array is desired to acquire the appropriate isotropic radiated power and signal to noise ratio. Additionally, bidirectional operation supporting transmit (TX) and receive (RX) in a single aperture is desirable to minimize the area and save power. This dissertation has focused on new architectures for scalable, bidirectional, and wideband phased arrays using IBM\textquoteright s fastest SiGe technology, 90 nm. In this dissertation, the first E-band scalable phased-array transceiver is proposed based on coupled oscillator architecture. Coupled oscillator phased arrays have the advantage of low power and low complexity, resulting in an architecture that easily scales to the number of elements as multiple die can be aggregated to form a larger array through local oscillator (LO) power distribution and intermediate frequency (IF) power combining. However, silicon processes introduce undesirable parasitics and manufacturing tolerances to the transistor and passive devices. When multiple oscillators are present in a single die, the oscillators couple through the substrate. The substrate coupling introduces additional parasitic coupling paths between oscillators; this causes pulling and, consequently, amplitude and phase variation between the oscillators. In addition, the parasitics from the injection node to the substrate deviate the ILO performance from its ideal behavior. Conventional analysis of the amplitude and phase noise typically ignores the effect of the silicon substrate parasitic effects. This dissertation investigated the nonlinear dynamics of an injection-locked oscillator (ILO), where the effective circuit parameters of ILO performance were observed. More specifically, new amplitude and phase equations are derived that took into account the transistor\textquoteright s device parasitics and silicon substrate\textquoteright s parasitic coupling effects, including the transistor injection node parasitic capacitance ($C_{P}$), substrate parasitic conductive ($R_{sub}$) and dielectric ($C_{j}$) features. The derived models are compared with both the simulation and measurement results. The proposed 2x2 transceiver phased array block diagram described in this dissertation employs 4 injection-locked oscillators (ILOs) operating at a lower frequency range (in this case, 1/4 of the desired LO frequency), followed by a frequency quadrupler, to form a beam in transmit and receive modes. The bidirectional front-end is designed to operate at E-band within 3-dB bandwidth. Since the ILO-based phase shifting is technically challenging at millimeter-wave bands due to the parasitics of the injection circuitry and the oscillator phase noise trade-offs, the high-frequency limitations of the ILO phase shifter is considered and wide locking range and a less parasitic sensitive solution for current injection using folded-cascode architecture is proposed. The proposed ILO-based phase array architecture result in low phase noise and low channel to channel isolation supporting 6 Gb/s data rate at 256 QAM modulation. The conventional architectures of the E-band transceiver require a wide tuning range, around 10 GHz, for the LO signal and wide-bandwidth IF blocks. The wide-bandwidth requirement of LO and IF frequency for mm-waves increases the power consumption and complexity of the system. This dissertation proposes a novel architecture, named the \textquotedblleft Image-selection\textquotedblright{} E-band phased array. This new architecture makes the upper-band (81-86 GHz) and the lower-band (71-76 GHz) of the E-band spectrum images of each other in comparison to the LO signal, which is located at the center frequency (78.5 GHz). Therefore, an image rejection architecture is desired to select the wanted band while rejecting the other. The significant advantage of this architecture is that it only requires an LO with the quadrature phases within a tuning range lower than 1 GHz . This will relax the system design trade-offs to the circuit impairments. For bidirectional operation purpose and preventing use of quadrature generation circuitry at direct intermediate frequency (IF) or radio frequency (RF) signal paths, sliding-IF weaver architecture mixers are employed with the phase inverter in the divider path to select the upper or lower band. This architecture leads in to a flat conversion gain over the bandwidth and low amplitude and phase imbalance. The achieved QAM modulation data rate from this technique is the state of art,\lyxdeleted{najmebi}{Mon May 29 19:43:48 2017}{ } 9Gb/s (64 QAM) with less than 5\% EVM and 12 Gb/s (16 QAM) with less than 10\% EVM.

Download or read book Design of 28 GHz 4x4 RF Beamforming Array for 5G Radio Front Ends written by Giovanni Scarlato and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Current state of wireless infrastructure sees mass migration to higher frequencies as much of the already used spectrum is insufficient in supporting the influx of numerous users and various data intensive mobile applications. Data rates are projected to increase by an order of magnitude and harnessing the necessary bandwidth below 6 GHz is not feasible. A move to higher frequencies sees not only increased fractional bandwidth, but also significantly enhanced antenna apertures as a result of beamforming capabilities. Due to device level complications with frequencies nearing the unit gain frequency of transistor technology, high output power is seldom found, and in conjunction with severe path loss, communication links cannot be established without the usage of antenna arrays. Phased array systems offer significant upside to the traditional array implementation as it permits reconfigurable directive communication. However, Ka-Band phased arrays still struggle to arrive at a reasonable tradeoff between design complexity, cost and performance. With a divide between both organic and printed circuit board (PCB) based approaches to the development of an antenna-in-package (AiP), this thesis sides with the latter. An antenna-on-PCB variant of the AiP is developed, which implements both commercially available RF laminates and RFIC front end modules to produce a 28 GHz 4x4 RF beamforming phased array that is found to exhibit extremely low loss (-0.66 dB), adequate scan volume (+/- 45 degrees, in E and H planes) and large bandwidth (3 GHz) for a single layer, non-isolated patch antenna design. Unit cell, infinite array analysis is emphasized and lattice resizing is leveraged to obtain desired scan performance, while significantly reducing design complexity via the absence of intricate isolation enhancement techniques. In an effort to aid in application based design, the AiP is extended to application of linearization where it is found that the inclusion of dummy elements along the perimeter of the package not only serve as element pattern enhancement, but also provide reliable means of output signal capture. Negating the traditional transmitter observation receiver (TOR) architecture, the AiP design as a TOR for millimeter-wave communication proves optimistic in the quest for maximum system efficiency.

Alhamed and published by . This book was released on 2021 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inevitable growth of mobile users and the proliferation of data-intensive applications are creating unprecedented challenges and opportunities. Therefore, the deployment of the fifth generation (5G) networks worldwide is accelerating to meet the increasing data-rate demands. Several mm-wave bands have been standardized as part of the 5G new radio frequency range 2 (NR FR2) at 24.25-52.4 GHz. The dissertation addresses the challenges of designing mm-waves ultra-wideband circuits and phased-array systems capable of operating at this widespread spectrum in advanced SiGe technology. The major contributions are the design of receive (Rx), transmit (Tx), and Tx/Rx beamformer chips and the implementation of multi-band 8×1 linear phased-array modules and large-scale 64-element phased array systems. The work in the 15-57 GHz Rx 4×1 beamformer culminated in the design and measurement of ultra-wide-band LNA, phase shifter, VGA, differential to single-ended stage and 4:1 on chip combining network with >40 GHz of bandwidth. Several circuit design techniques are introduced to break the gain-bandwidth (GBW) trade-offs in conventional beamformer designs. A peak electronic gain of 24-25 dB and a 4.7-6.2 dB noise figure is achieved with a 15-57 GHz record 3-dB bandwidth. The mm-wave multi-band transmit phased-array contributions focus on the design of 16-52 GHz 4×1 transmit beamformer chip. The Tx IC has four differential RF beamforming channels each with an active balun, vector modulator based phase shiftier, VGA, and a 2-stage class-AB power amplifier (PA). Circuit techniques employed in this work are selected to fulfill the power and bandwidth requirements with compact area utilization. An 8-element phased-array Tx module is demonstrated achieving broadband performance with +/- 60 degrees scanning capability. The work in the 64-element multi-band transmit and receive phased arrays employs the slat-array architecture using 16×1 linear arrays each has four 4×1 beamformer chips and end-fire tapered-slot antennas. Architecture and system analysis are presented to realize 16-52 GHz multi-standard operation. The 64-element Tx array achieves an EIRP of 50-51.7 dBm and 47.6-49 dBm at Psat and P1dB, respectively, at 24.5-48 GHz.
