Viewpoint                               ***************                              Optimism Rampant at Long Beach MTT-S                              Although sales are still relatively flat for many high-frequency                               manufacturers, the general tone of exhibitors at last week's                               Microwave Theory & Techniques Symposium (MTT-S) in Long Beach, CA                               was optimistic. Several companies even mentioned direct sales orders                               from attendees at the show. Most indicated that they expected                               business to pick up during the second half of 2005, especially in                               key areas of defense electronics and homeland security.                              In terms of technology and products, ultrawideband (UWB) devices                               made a strong showing at MTT-S, notably a series of UWB                               system-on-chip (SoC) devices from M/A-COM ( http://nls.planetee.com/t?ctl=CEAD:FFCBF ).                               Based on an advanced silicon-germanium (SiGe) process, the 24-GHz,                               plastic-packaged transmitter and receiver SoCs target high-end                               automotive radar systems (rather than the more competitive,                               lower-frequency UWB data-communications applications).                               As expected, the MTT-S featured scores of significant software                               advances, along with new components (even involving some                               "disruptive" technologies, such as that offered by Dielectric                               Laboratories) and some impressive test instrument introductions. To                               celebrate some of these new products, the next several issues of                               this newsletter will include various highlights from the show, for                               those who could not be there.

According to Brian Bedrosian, senior product line                               manager for Broadcom's Home and Wireless Networking Business Unit,                               "as manufacturers utilize new bus architectures and integrate Wi-Fi                               capabilities into smaller devices, Broadcom is working with leaders                               like Fairchild to develop solutions that meet the latest size, cost,                               and performance requirements."

Leveraging expertise                               in ceramic substrate materials, the firm has developed a                               patent-pending high-quality-factor (high-Q) temperature-stable                               cavity resonator. These high-Q resonators (Qs to 1500 at 2 GHz),                               which are compatible with surface-mount packaging and chip-and-wire                               assembly techniques, are available for single frequencies as high as                               67 GHz with frequency tolerances as tight as 0.1 percent. Suitable                               for microwave and millimeter-wave oscillators in automotive,                               commercial, and military applications, the self-shielded resonators                               feature high stability with temperature at a fraction of the size of                               other resonator technologies. The company has also applied its                               "disruptive" ceramic technology to the development of patent-pending                               single- and multiple-pole cavity filters for microwave and                               millimeter-wave applications.

Ideal for multiport and balanced component testing, the company's                               model ZVT8 VNA has a reflectometer at each of its eight test ports                               for simultanous testing on multiple components or components with                               multiple ports. The analyzer covers a range of 300 kHz to 8 GHz with                               +13 dBm minimum test signal power at each port and a dynamic range                               of better than 120 dB.

The                               company's model PE9308 prescaler, which is designed for space-based                               and demanding military applications, is the first CMOS device to                               operate at X-band and Ku-band frequencies. According to Jim Cable,                               Peregrine's president and chief executive officer (CEO), "UltraCMOS                               technology has broken the speed barrier long associated with                               traditional CMOS processes." The prescaler consumes about one-tenth                               the power of equivalent GaAs devices, at typically 25 mA current                               from a +2.5-VDC supply.

The test                               bench allows engineers to evaluate the impact of link impairments on                               essential system performance parameters, including frame error rate                               (FER), bit error rate (BER), and symbol error rate (SER). The                               cdma2000 test bench consists of transmit and receive blocks and                               support various frame sizes, data rates, and numbers of                               communications channels, such as traffic channels, pilot channels,                               and includes an orthogonal channel noise simulator (OCNS).                              In other software news at MTT-S, Sonnet Software demonstrated one of                               the industry's first cluster computer applications of its                               electromagnetic (EM) simulation software, using a multiprocessor                               rack-mount computer system to perform analyses on planar microwave                               structures in mere minutes that once required hours or even days.

Suitable for fighter                               aircraft and unmanned aerial vehicles (UAVs), the cable assemblies                               seemingly defy the laws of physics by exhibiting no attenuation from                               0.5 to 18.0 GHz. In reality, they incorporate wideband                               monolithic-microwave-integrated-circuit (MMIC) gain blocks to                               overcome the normal loss of the cable, with bias provided through                               the termination connectors.

Ghavami, L. B. Michael, and R. Kohno, Ultra Wideband                               Signals and Systems In Communications Engineering focuses on the                               signal-processing aspects of UWB consumer communications systems,                               rather than on UWB radar systems. It includes sections on generating                               UWB waveforms, modeling indoor communications channels (since most                               UWB communications systems are for short-range indoor applications),                               UWB antennas and antenna arrays, and positioning and location                               applications with UWB technology. The text concentrates on a basic                               presentation of the technology, avoiding current debates over the                               merits of the Intel versus Motorola approaches to UWB                               implementation.
