Viewpoint                               ***************                              Achieving Affordable WiMAX Components                              Demand for more services (and bandwidth) continues to send wireless                               designers scrambling. Some solutions can be found in higher-order                               modulation formats, such as orthogonal frequency division multiplex                               (OFDM) techniques. But often, it is a matter of raising the                               operating frequency in search of available bandwidth. Implied with                               the increase in frequency is an increase in cost. The trend was                               evident with wireless local area networks (WLANs), as they moved                               from 2.4 GHz to the 5-GHz range. And the trend is permeating                               emerging WiMAX applications, which may one day extend to the                               millimeter-wave frequency region.                              Impressively, in response to the demand for higher-frequency                               components, electronic designers respond. One example is the                               high-performance 11-GHz power detector developed by Linear                               Technology ( http://news.mwrf.com/t?ctl=24D23:49027F ), detailed                               below, and selling for just a hair over $3 each. Another example                               is a line of LDMOS power transistors introduced by Freescale                               Semiconductor ( http://news.mwrf.com/t?ctl=24D1E:49027F ) with as                               much as 16 W true linear output power from 3.4 to 3.8 GHz.                               These devices (look for the Product Feature in the upcoming                               April issue of Microwaves & RF) literally stretch the high-frequency                               ceiling once accepted for LDMOS technology.                              It has been said many times that this is a resourceful industry.                               High-frequency design analog engineers do not often receive the                               acclaim of their digital brethren. Yet, they continue to show                               amazing creativity and a willingness to tackle almost any challenge,                               even to the extent of making millimeter-wave devices affordable to                               the masses.

With the                               highest-frequency coverage currently available in a semiconductor                               power detector, this device is ideal for emerging WiMAX wireless                               applications, power control in power amplifiers (PAs). It draws only                               500 microamps per detector and handles a wide input range of -32 to                               +12 dBm. The detector boasts 40-dB dynamic range and 45-dB                               channel-to-channel isolation. It includes buffer amplifiers and is                               housed in a miniature, surface-mount package measuring 4 by 3 mm. It                               is prices at $3.20 each in 1000-piece quantities.

The firm's Xero Wafer sits less than 0.5 nm away from a synthetic                               diamond substrate and features unprecedented heat- and                               power-handling capability for high-power, high-frequency electronic                               designs. The close proximity of a device's active region to the                               diamond results in efficient transfer of heat away from the active                               device. The GaN on diamond wafers, which will be initially offered                               in 10 x 10 mm square pieces, are currently sold for $450 per unit                               through the company's online store.

News                              *********                              AVX Adds High-Current RoHS-Compliant Caps                              Capacitor supplier AVX Corp. (Myrtle Beach, SC) has developed                               RoHS-compliant medium-and high-voltage ceramic capacitors for                               high-current applications such as military, harsh environment power                               supplies, high-voltage coupling and DC-blocking. The SK series is                               suitable for medium-voltage (to 500 V) applications, while the SV                               series of multilayer capacitors (MLCs) is designed for high-voltage                               applications (to 5 kV). According to Craig Hunter, AVX Strategic                               Marketing Manager, "The added advantage of both these capacitor                               families lies in a special internal design minimizing the electric                               field stresses within the MLC. This results in a significant                               reduction of partial discharge activity within the dielectric and                               has a major impact on the long-term reliability of the product."

In addition, the system will be able to accommodate                                commercial services, which will allow customers to use their                               wireless  devices throughout CTA's subway system and provide an                               additional  revenue stream for the agency. The project was                               competitively bid and completed through a collaborative effort                               between Powerwave and Aldridge Electric Inc. (Liberty, IL), one of                               the largest electrical contractors in the US.
