Available in PDF, EPUB and Kindle. Book excerpt: During the past years, wireless communication systems have been rapidly advancing to meet the high data-rate requirements of various emerging applications. However, the existing transceivers have typically been demonstrated using CMOS-compatible technologies that deliver a relatively low equivalent isotropic radiated power in a small unit cell. Moreover, the particular device characteristics are limiting the linear region for operation. Therefore, the main focus of this dissertation is to present and discuss new design methods for transceivers to solve these issues. To reduce the complexity of the transceiver module for further phased-array scaling, a low-noise power amplifier design approach is designed using a 0.15-μm GaN-on-SiC high-electron mobility transistor technology (HEMT). Utilizing a traded off interstage matching topology between loss and bandwidth, the conversion loss induced by the matching network could be effectively reduced. A stacked-FET configuration was adopted to enhance the power handling of the RF switch. Further improvement on the isolation bandwidth was investigated using theoretical analysis on the intrinsic effect of the passive HEMTs. With the successful implementation of the RF front-end circuits, transceiver modules were integrated on Rogers RO3010 substrate. The planar dual exponentially tapered slot antenna phased-array system showed a compact size with simple biasing network compared to the conventional transceiver approach. The presented T/R module was characterized with an over-the-air test at a distance of 1 m, overcoming the free space path loss of 64 dB. It also shows a high flexibility for further integration with a larger number of array systems, which is very promising for future 5G communication systems.

Download or read book High Performance Millimeter Wave Transceiver Circuits for V-band Applications Using Silicon Processes written by Chi Yiu Law. This book was released on 2011. Available in PDF, EPUB and Kindle. Book excerpt: Wireless applications are embedded into many electronic products. The lower frequency bands have been allocated with various applications, but this allocation increases the concern of bandwidth congestion. V-band spectrum, from 57 GHz to 64 GHz, has great potential due to its wide available bandwidth. Recent research and commercial products have shown that, the feasibility of wireless systems in the millimeter-wave frequency band improves as technology progresses. However, the required bandwidths are still high for the silicon technology. Moreover, at millimeter-wave frequencies, many device parasitics are significant. Parasitics neglected at lower frequencies such as gate inductance and resistance may turn into major design disruptions. The intrinsic model that is heavily relied upon often becomes insignificant. Most of the time, designers have to spend tremendous amounts of time on simulation and device modeling to achieve adequate performance for V-band. Another noticeable change for the millimeter-wave circuit is the usage of passive components. The design of microstrip structures to replace traditional lumped components becomes favorable due to the size reduction of microstrip structures at millimeter-wave frequencies. To demonstrate the design methodology, a few often used transceiver circuit blocks have been designed. These blocks includes the Power Amplifier (PA), which is normally used in the transmitter chain, a Low Noise Amplifier (LNA), the first active circuit on the receiver chain, and a Voltage-Controlled Oscillator (VCO), which is used in both transmitter and receiver chains. The power amplifier was fabricated using 90 nm TSMC CMOS process. It outputs 20 dBm of saturation power and has power gain of 20.6 dBm. The Low Noise Amplifier and Voltage-Controlled Oscillator were fabricated using a 0.13 [mu]m IBM BiCMOS SiGe 8HP process. The LNA has gain of 17 dB across the 57 GHz to 64 GHz band and has noise figure of 4.5 dB. The VCO has a phase noise of -111 dBc at 1 MHz of frequency offset of 60 GHz and tuning range from 56 GHz to 65 GHz.
