Gov. Mike Easley announced that Andrew Corp. , a global designer, manufacturer and supplier of communications equipment and services, will move into a new facility in Wayne County in 2006 adding 204 new jobs and retaining and relocating 232 existing jobs from the company's Smithfield facility. The project represents...

At the request of the member companies and with guidance and support from the Defense Advanced Research Projects Agency (DARPA), the MEMS Industry Group engaged in a comprehensive effort to understand the realities and perceptions about the reliability of MEMS: from analyzing available data with successes and challenges, to...

Times Microwave Systems has introduced a new and unique addition to its popular SilverLine™ RF test cables. SilverLine-TG™ (TuffGrip™) is specifically designed to address the needs of cellular infrastructure, wireless Internet, and public mobile radio site installers and test technicians. Fig. 1 Actual cell site disconnected jumper cable. Extreme...

A new family of +12 V power amplifiers designed for use in wireless infrastucture applications has been introduced. The models AP501, AP502, AP503 and AP504 are targeted for driver and final stage amplifier applications where high linearity and high power are primary requirements. The combination of high power and...

Until recently, traveling wave tube (TWT) technology was the only technology capable of meeting the bandwidth and power requirements of high power L-band applications such as power testing radar components and for military/automotive RF immunity testing. Solid-state technology can, however, offer key performance advantages over TWT technology, particularly with...

When the Hubble Satellite was launched in 1990, the joke was that it was the third best optical satellite in space, but that the two better ones were pointed in the opposite direction. While it is still true today that more satellites are looking downward than upward, satellites are...

Hittite Microwave Corp. showcased a montage of new products at RWS 2006, held January 17-19, 2006, in San Diego, CA. Among the products on display included model HMC-C026, a GaAs MMIC distributed power amplifier connectorized module that is ideal for military EW/ECM, space, test equipment, wideband telecom, microwave radio...

Metamaterials ,1,2 with simultaneous negative permittivity and permeability, are promising materials for new types of microwave components. In metamaterials, the waves are propagating with anti-parallel phase and group velocities, as demonstrated by backward waves. 3 Recently, an extended transmission-line approach to metamaterials, low loss and broadband structures was proposed...

Microwave Downconverter The model PN9276 is a 40 GHz microwave downconverter that provides the combination of high bandwidth with low noise performance. This model is designed for radar, commercial wireless, satellite terrestrial microwave links and calibration labs. This downconverter plugs into any PN9000 phase noise analyzer or PN9500 wideband...

The Wilkinson divider has long been popular with RF designers. In recent years, off-the-shelf, surface-mount technology (SMT) components of this type have become available and provide tremendous cost savings in high volume pick and place manufacturing. Some of its applications are found in power amplifier design and modern communication...
