Short Course 1
Metamaterial Engineering for Microwaves
Lecturer: Tatsuo Itoh, UCLA, U.S.A.
This course is intended to provide realistic approaches to applications of metamaterial structures, specifically the so-called left handed or double negative materials, for microwave engineering. After brief historical remarks, some fundamental concepts are explained. A number of microwave components with unique characteristics are presented mostly based on the transmission line approach, called the Composite Right/Left Handed structure. Classes of the components discussed are antennas, passive devices, active and nonlinear circuits, and two-dimensional beam optics structures. Engineering aspects including the fabrication issues and homogeneity problems are discussed.

Digital RF Processor (DRPTM): All-Digital TX and Discrete-Time RX
Lecturer: Robert Bogdan Staszewski, Texas Instruments, U.S.A.
RF circuits for multi-GHz frequencies have recently migrated to low-cost digital deep-submicron CMOS processes. Unfortunately, this process environment, which is optimized only for digital logic and SRAM memory, is extremely unfriendly for conventional analog and RF designs. We present fundamental techniques recently developed that transform the RF and analog circuit design complexity to digital domain for a wireless RF transceiver, so that it enjoys the benefits of digital approach, such as process node scaling and design automation. All-digital phase locked loop, all-digital control of phase and amplitude of a polar transmitter, and direct RF sampling techniques allow great flexibility in reconfigurable radio design. Digital signal processing concepts are used to help relieve analog design complexity, allowing one to reduce cost and power consumption in a reconfigurable design environment. The ideas presented have been used in Texas Instruments to develop two generations of commercial digital RF processors: a singlechip Bluetooth radio and a single-chip GSM radio.

RF MEMS Circuits for High Frequency Applications
Lecturer: Linda Katehi and Dimitris Peroulis*, Univ. of Illinois, *Purdue Univ., U.S.A.
RF MEMS has been identified as an area which has the potential to provide a major impact on existing RF architectures in sensors (radar) and communications by reducing weight, cost, size, and power dissipation. The impact of this technology to communication system cost, size and volume is a few orders of magnitude. Key MEMS devices for current RF architectures are switches and microrelays in radar systems and filters in communications systems. Several RF MEMS switches have been developed in the past decade. The main driving force behind these efforts is the outstanding RF performance demonstrated by the MEMS devices. In most cases, RF MEMS switches have been electrostatic in nature. They have the distinct advantage of using only a few mW of DC power as compared to several mW for solid state devices. This presentation will cover a broad range of RF MEMS devices including switches and varactors and will discuss in detail issues related to device architecture and device reliability.

Short Course 4
Wireless Communications Standards, Systems, and RFIC Specifications
Lecturer: Jenshan Lin, Univ. of Florida, U.S.A.
This tutorial links RFIC design specifications and system requirements defined in wireless communications standards. Many RFIC designers design the circuits without knowing where and how the specifications come from. The objective of this tutorial is to let attendees learn how to derive RFIC specifications from wireless communication standards, tradeoffs in different transceiver architectures, and an overall picture of RFIC and wireless communication systems. As RFIC design advances from componentlevel building blocks to system-level integration, this link between standards and RFIC specifications is becoming more important. A reference system design of GSM receiver will be given as an example.
