MEMS (Micro-electromechanical Systems) are starting to be the “Swiss Army Knives” of modern consumer electronics: they can take the form of (or be incorporated in) accelerometers, gyroscopes, magnetometers, altimeters, screens, projectors and microphones. New data from ABI Research indicates that strong growth in the MEMS market over the next...

There is no question that in the long term LTE will become the mainstay 4G network technology, although its universal use is still in the future. Until then, says ABI Research, some service providers will benefit from a dual-platform strategy based on both LTE and WiMAX. Who stands to...

Industry News Texas Instruments has signed a definitive agreement to purchase National Semiconductor in an all-cash transaction of about $6.5 B. This merger will unite two industry leaders who have a common commitment to solving analog needs. Both companies will operate independently pending close of the acquisition that is...

Passive intermodulation (PIM) has been recognized as a potential problem in communications systems for nearly 50 years. The phenomenon occurs when two or more signals encounter a nonlinear junction and “child” frequencies are generated that are mathematically related to the “parent” signals. With the advent of cellular communications, PIM...

With the rapid development of communication technology, there have been increasing demands for advanced radio frequency (RF) filters with small size, wide stopband and high selectivity. To realize better selectivity, the generation of transmission zeros is very important in the synthesis of modern filters. Most of the research efforts...

Copper clad laminates used in the microwave Printed Circuit Board (PCB) industry have many properties of concern. The dielectric constant (relative permittivity or ε r ) is one of the most critical. Many design engineers have made the assumption that this property is a rigid value; however, often that...

Recently, in order to achieve highly efficient amplification, switch mode power amplifiers (SMPA) with theoretical 100 percent efficiency have been introduced. However, in practice, the efficiency of SMPA cannot achieve as high as 100 percent because of the parasitic parameters of the transistor, the losses of matching networks, etc....

Harris Corp. introduced an unfurlable space antenna designed to support emerging requirements for high-throughput Ka-band satellites. The new Harris Ka-band antenna greatly increases the gain and potential spot beams currently available to spacecraft manufacturers and service providers. The increased frequency reuse provided by the additional spot beams enables higher...

Lockheed Martin announced that the US Missile Defense Agency has awarded it a $43.3 M contract for concept definition and program planning for the Standard Missile-3 Block IIB (SM-3 IIB). The new missile, formerly known as the Next Generation Aegis Missile, will provide early intercept capability against intermediate- and...

Raytheon Co. was awarded $42 M for the initial concept development and program planning for the Standard Missile-3 Block IIB, which is the Missile Defense Agency’s next-generation Aegis missile. “Raytheon is the lowest-risk, lowest-cost, most-technically capable provider of missile defense solutions,” said Frank Wyatt, Vice President of Raytheon’s Air...
