The GaAs market staged a strong recovery toward the end of a tumultuous 2009 as a result of positive trends in wireless markets. The Strategy Analytics GaAs and Compound Semiconductor Technologies (GaAs) service report, "GaAs Industry Forecast 2009-2014," calculates that despite a recession, GaAs industry revenues managed to escape...

Digital radio has just begun to see consumer adoption in the US and Western Europe. By the end of 2010, about four million digital radios using iBiquity's proprietary HD Radio technology will have shipped in the US. In Europe (led by Britain) governments have chosen the DAB standard and...

While microwave and millimeter-wave high-power vacuum electron devices (VED) remain "below the radar" of many industry observers, the total available market (TAM) for this segment is over $1 B. The size of this market continues to surprise everyone and its longevity and firm resistance to RF power semiconductor encroachment...

TiaLinx Inc., a developer of miniaturized mm-wave radars with integrated radio and antenna arrays, recently announced the launch of the Eagle45-W, a hands-free precision Sense-Through-The-Wall Imager. The lightweight, ultra-wideband (UWB), multi-Gigahertz RF imager requires only limited use of hands and is operated through a miniaturized display. Through the software...

Industry News Roger W. Sudbury , a longtime MIT Lincoln Laboratory staff member and dedicated IEEE volunteer, passed away on August 22, 2010. Joining Lincoln Labs in 1969 as a technical staff member researching solid-state devices for modern radars, he went on to become the Laboratory’s executive officer, serving...

Electronic Support Measures (ESM) receivers geo-locate threat emitters by measurement of angle of arrival (AOA), time difference of arrival (TDOA) or frequency difference of arrival (FDOA). Errors in the measurement of phase and frequency may be contaminated, due to spurious responses that yield irresolvable errors. Phase Contamination Radar signals...

Microwave printed antenna arrays (PAA) have various advantages over conventional antenna systems, due to their low cost, great reproducibility and the possibility of integration with other microwave circuits. Because of this, they are often used in telecommunication systems, such as indoor and outdoor wireless LANs, point-to-point and point-to-multipoint, and...

The direct plated copper (DPC) process on metallized ceramic substrate was originally created to replace the direct bonded copper (DBC) process because of its better electrical, thermal and mechanical performance. 1 Compared to DBC, DPC provides a very strong bond strength between the Al2O3/AlN substrate and the copper metal,...
