Saab and Tata Consultancy Services Ltd. (TCS) have signed a Letter of Intent to create an aviation technology design and development center in India. Together the two companies intend to establish a common development center that both parties can benefit from. The collaboration is seen as the start of...

Applied Micro Circuits Corp. , a leader in high speed datacenter and optical transport, embedded Power Architecture® processing and storage solutions, announced that NetXen Inc. , a leader in mainstream 10 Gigabit Ethernet connectivity, has chosen the company’s 10 Gigabit Ethernet QT2025 Physical Layer integrated circuit technology for use...

A new range of high power, broadband amplifiers has been developed to capitalize on the inherent advantages of Gallium Nitride (GaN). With instantaneous bandwidths of 2 to 6 GHz and high reliability, the AS0206 family of amplifiers is well suited to several markets. In particular, its inherent reflected-power tolerance...

The authors describe a low profile CPW and microstrip-fed half-circle planar monopole antenna with dual rectangular slit, which has similar radiation pattern properties for Ultrawideband applications. In this case, the inserted dual slit on the monopole also leads to enhancing the wide band impedance. The inserted dual slit on...

Spectrograms are graphs which display signal power as a function of both time and frequency on a single plot. One axis represents time and another, frequency. Colors or grayscale values are used to indicate magnitude. Recent enhancements to the mathematics which are used to produce spectrograms have greatly enhanced...

Orthogonal frequency division multiplexing (OFDM) is a form of digital modulation used in a wide array of communications systems. This paper will explain what OFDM is, why it’s important, where it’s used, and what test instrumentation is required to maintain it. Perhaps we should first explain what is so...

There will be increasing need for high confidentiality, integrity, and authentication for the wide deployment of the next generation of RFID. Beside these issues, focus will also be on avoiding encryption algorithms; which require more complex modulation, to secure communication between RFID’s tags and readers. In this paper, we...

Switch Selection Guide Agilent’s new “RF and Microwave Switch Selection Guide” provides comprehensive information on the company’s entire portfolio of switches. The guide provides an overview of electromechanical and solid-state switches and switch drivers. Characteristic switch parameters such as switching speed, isolation and insertion loss including typical applications and...

Short on RF Engineers? Consider H1B This column advocates for considering non-US professionals to fill in the steadily growing shortage of RF engineers. In addition to presenting the practical and fiscal advantages, this article also highlights the contribution of “imported” engineering talent to securing future domestic jobs. Unlike the...
