Smart Partitioning for WiMAX Radios

November 13, 2006
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...

WiMedia UWB PHY Design and Testing

New wireless networking standards commonly present design challenges in the physical layer, which in turn present circuit simulation and testing challenges. The WiMedia MB-OFDM UWB signal with its low power, hopped, 528 MHz wide OFDM format is a curren...
November 13, 2006
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...

A Broadband Double Dipole Antenna with Triangle and Rhombus Shapes and Stable End-fire Radiation Patterns for Phased-array Antenna Systems

A broadband microstrip-fed printed antenna is presented for phased-array antenna systems. The presented antenna consists of two parallel dipoles of different lengths to obtain two main resonances. The distance between the two dipoles is adjusted to red...
October 13, 2006
Microstrip antennas have recently gained wide popularity, because they exhibit a low profile, small size, lightweight, low manufacturing cost, high efficiency, and an easy method of fabrication and installation. Furthermore, they are generally economical to produce since they are readily adaptable to hybrid and monolithic integrated circuit fabrication techniques...

An X-band Phased-array Radar MMIC Chip Set

Mimix Broadband Inc., Houston, TX

Radio detection and ranging or RADAR has been around since its first implementation in the early 1900s when the use of radio waves was first used to detect the presence of ships in dense fog. The actual acronym was not coined until the early 1940s. X-band radar, in particular, has been around since the outset of World War II and continues to see extensive use. Typical X-band radar applications include air traffic control, detection of precipitation, speeding traffic and military use. Military uses include detecting and tracking aircraft, ships, missiles and other objects with the intention of harming any of our armed forces protecting our country and its interests. Various types of radar include continuous wave (CW), dual-pole, phased array, pulsed, single-pole and synthetic aperture radar (SAR). Many of the advanced X-band radars used today are typically based on active phased arrays requiring the use of many multiple phase array element sections.
