The new paint-on antenna technology was tested successfully during flights on the SA-60 Spherical Airship in the Nevada desert. Derived from a series of polymer-based dielectrics and highly conductive paint, the paint-on antennas are designed to be used to establish new high altitude communications and surveillance platforms. With no...

Over 40 million Global Navigation Satellite System (GNSS) receivers were shipped in 2005, but in 2011 the market will have grown to nearly 300 million shipments, according to a new study from ABI Research that tracks GNSS markets across eleven vertical industry segments. That growth will not occur evenly...

Industry News Dr. Leo Young Dr. Leo Young died September 14, 2006, of complications from cancer. He was 80 years old. He was a pioneer in the microwave industry and served as president of both MTT-S and IEEE. He received his BS degree in physics and math in 1946...

Helical type resonators are widely used for frequencies below 0.5 GHz, mainly for mass and dimensional considerations. Replacing the more traditional TEM combline types or dielectric resonators by helical resonators significantly reduces the size and mass of the filters at the expense of the insertion loss. The rather complicated...

Current research studies are drawing more and more attention on the memory effects of high power amplifier linearization, especially for cellular base transceiver system applications. 1,2 Although many studies on power amplifier linearization have been conducted, linearization of strongly nonlinear systems with large memory, which exacerbates the performance of...

Kulicke & Soffa Industries Inc. closed the previously announced purchase of Alphasem, a supplier of die bonder equipment, from Dover Technologies International Inc., a subsidiary of Dover Corp. The purchase price was $27.1 M in cash, after a working capital adjustment and subject to further post closing adjustments. "We...

Comtech Telecommunications Corp. announced that its Tempe, Arizona-based subsidiary, Comtech EF Data Corp. , received a $2.8 M order from a leading communications integrator for its turboIP® performance enhancement proxy. The units will be deployed to support US Government installations around the world. Comtech EF Data's turboIP performance enhancement...

Keithley Instruments Inc. , a leader in solutions for emerging measurement needs, announced it has partnered with Mesatronic Group , Voiron, France, to develop advanced probe cards for semiconductor parametric testers used in RF and low current DC applications. William Merkel, marketing director for the Keithley Parametric Test Product...

The need for broadband wireless access (BWA) has long been acknowledged as the next step in the evolution of Internet access. Unfortunately, the lack of robust technology at a competitive price has been a barrier to its implementation. Today, though, momentum to cross the chasm is gathering—early adopters have...

With the blessing of the WiMedia Alliance, the stage is set for widespread implementation of certified wireless USB and next-generation Bluetooth 3.0 products, using multi-band orthogonal division modulation (MB-OFDM)-based ultra-wideband (UWB) physical layer (PHY). Wireless USB supports data rates of 53.3, 80, 106.7, 160, 200, 320, 400 and 480...
