The telecommunications sector accounts for roughly 4 percent of the global electricity consumption. However, the sector is actively participating in efforts to reduce energy use – both for economic reasons, such as reducing operating expenses, and for environmental reasons.
Global Navigation Satellite System (GNSS) based solutions are highly accurate in most cases, but there are circumstances where they are not as effective, such as in dense urban environments with reduced satellite visibility or indoor areas with low signal levels. LTE Location Based Services (LBS) are designed to determine where a device is located to assist in its effectiveness. This Rohde & Schwarz white paper describes limitations of GNSS systems, as well as LTE cellular based alternatives within 3GPP Release 9.
Improvements have been made to GaN amplifiers at microwave frequencies that have increased their generated output power levels while also shrinking the size of the system. These developments, however, present the challenge of providing sufficient thermal management. This Qorvo® application note discusses the thermal issues involved with using high-powered, small packaged (e.g. QFN) GaN amplifiers within high power CW systems. Download the full paper for considerations on component mounting in order to provide a low thermal impedance path to the system heat sink for optimum operation and reliability, using the TGA2307-SM as an example.
For many years, TWTA technology has been the only option for pulsed field generation within high field-strength EMC radiated susceptibility testing. AR now offers high-power solid state pulsed amplifiers as a very attractive alternative to this technology. These SP-series amplifiers include various frequency ranges and output power levels capable of meeting several standards. This application note discusses key features and benefits of this new line of solid state pulsed amplifiers, and how they are optimized for use in applications such as EMC radiated susceptibility testing.
This article describes a patented multi-tone testing process that allows users to test multiple tones per dwell period in order to increase test efficiency by a factor approximately equal to the number of tones tested. The multi-tone concept’s history is covered, along with information on its effectiveness, and information on potential future applications.
