Creating the complete transmission path of a satellite in training, development, troubleshooting, or system set-up applications requires three components: two earth terminals and a spacecraft. While terminals are generally accessible, satellite accessibility is more problematic, requiring costly leased time on an orbiting spacecraft and offering no control flexibility. Often,...

When implementing the evolution of TDMA wireless networks to GSM/GPRS and then W-CDMA, service providers “overlay” GSM/GPRS by integrating a new base transceiver station (BTS) with the existing TDMA BTS. Carrier signals from the new BTS are fed through the TDMA transmit chain to the existing antennas, and receiver...

For mobile phones, WLAN and other wireless applications, RF engineers need to perform sophisticated IC designs under strict time-to-market constraints. To make this possible, with as few prototyping cycles as possible, RFIC design tools must incorporate efficient methods for analyzing circuit behavior, accurate semiconductor models and flexible system modeling...

Microwave engineers have been forced to verify the validity of their high frequency design interconnects either by manual inspection or by using layout versus schematic tools designed for analog/digital design. Such tools, which are well established for low frequency design, tend to be less than optimal for high frequency...

The state-of-the-art indoor wireless systems operating at microwave frequencies (approximately 2.45 and 5.5 GHz) have been standardized in conformance with different multiplexing schemes and modulation techniques. The underlying design considerations 1,2 aim at realizing robust operation of several interconnected and coexisting hosts 3 across RF links. These links are...

The Global Positioning System (GPS) is a worldwide satellite navigation system, which consists of a constellation of 24 satellites and their ground stations. GPS signals are specially coded satellite signals that can be processed in a GPS receiver. When receiving the signals from at least four satellites, a receiver...

Commercial communications satellite operators face a difficult problem. In the rapidly evolving global telecommunications industry, entire market segments can emerge, thrive, change and disappear during the fifteen-year on-orbit lifetime of a modern communications satellite. To address these changing market needs, it would be desirable to have a communications payload...

Texas hospitality was definitely in abundance as the participants descended on Fort Worth for IMS 2004. Hot, humid weather and more rain than was comfortable did not dampen the enthusiasm or diminish the attendance at the MTT-S International Microwave Symposium held June 6 to 11. Overall attendance fell just...

High Performance Spectrum Analyzers The PSA series of high performance spectrum analyzers is for designers of WLAN, satellite communications and radar systems, as well as amplifiers for 3G wireless systems. The recently added two optional enhancements broaden bandwidth and analysis capabilities. The enhancements include a digitizer that enables signals...

Industry News L-3 Communications , a defense contractor, announced that it will acquire Cincinnati Electronics , a provider of military infrared imaging sensors and space launch electronics, for approximately $172 M in cash. Cincinnati Electronics’ customers include the US Army, US Air Force, US Navy and US Marine Corps....
