As wireless communications such as 3G cellular networks and wireless LAN play an increasing role in everyday life, data transfer rates, broadband communication channels and carrier frequencies are increasing. To meet these demands, the industry is turning to differential and multiport designs for RF and microwave components. During the...

As consumers adopt more data intensive applications and want access to that data in more locations, the need for high speed wireless data communications is increasing dramatically. There are a host of wireless standards emerging to satisfy this need for increased data. 2.5G/3G, Wi-Fi and WiMAX systems are all...

A few decades ago, military laboratories were the source of much of the technology that emerged in the consumer world, the most famous example being the Internet, which began as a communications network designed to function in the event of a nuclear strike. Today, some in the military believe...

On August 3, 2004, the MESSENGER probe 1 was launched on its six-year journey to the planet Mercury. The acronym MESSENGER derives from MErcury Surface, Space ENvironment, GEochemistry and Ranging. Commissioned by NASA, and built and operated by the Johns Hopkins University Applied Physics Laboratory (JHU/APL), the probe carries...

Recently, as wireless communications systems get smaller and lighter and are able to perform multi-functions, microwave components that have a small size and better performance are required. One of the methods used to meet these requirements is the low temperature co-fired ceramics (LTCC) process technology. The multi-layer technology using...

Applications of microwave heating are well known and are described in many publications (an exhaustive list of references is given by J. Thuery 1 ). A very promising application of microwave heating in agriculture is to replace toxic, dangerous and environment-unfriendly chemicals used to control vegetation, as described in...

If your company participates in the aerospace and defense industry, you probably have encountered customs agents, customers and other third parties asking whether you are ITAR compliant. While being ITAR compliant is crucial, companies exporting any goods must also remain compliant with regulations enforced by the US Customs Agency,...

Anyone who deals with military communications systems today is certain to come face-to-face with the concept of network-centric warfare. The heart of this concept is a reliable and ubiquitous communications system. Success in combat requires that the necessary information and communications links always be made available exactly when and...

The transistor LC oscillator is at the heart of any wireless communications system. Due to their low cost, design simplicity and ease in practical implementation, for example, MOSFET-based oscillators are widely used in modern wireless handset applications. This three-part tutorial highlights the basics of the oscillator circuit design, setting...
