The attendance was high at this year’s IEEE Radar Conference as engineers gathered at the Boston-area venue to learn from and interact with their peers. The organizers, led by conference general Chairman, Dr. David L. Briggs dedicated the conference to showcasing recent innovations and achievements in radar systems and...

Aeroflex has been awarded a five-year contract from Thales for the fulfillment of its second Measurement Equipment Management Service (MEMSII) program in the UK, having previously been responsible for the initial MEMSI service contract. The objective of MEMSII is to provide Thales with the most cost efficient way of...

IEEE 802.16e mobile WiMAX is currently being developed as the next-generation communication standard competing with wireless local area network (WLAN), code division multiple access (CDMA), evolution data optimized (EVDO), enhanced data rates for GSM evolution (EDGE) and high speed downlink packet access (HSDPA), even though early applications for mobile...

High performance bandpass filters, with miniaturized size, narrow bandwidth, wide stop band and low cost, are required in modern wireless communication systems, especially in mobile and portable Internet systems. Planar reduced-size filters, such as λ/2 hairpin resonator1 and slow-wave resonator 2 filters have already been published. These filters have...

Efficiency, output power and compactness are the most important parameters of a system for RF/microwave transmitter applications. The power amplifier consumes most of the DC power in a transponder. Thus, much attention is required to maximize the efficiency of the power amplifier. A high efficiency power amplifier allows compact...

NEC Corp. has licensed its US digital microwave radio (DMR) patents and counterpart patents, covering fundamental telecommunication techniques such as quadrature amplitude modulation (QAM), to Microwave Networks Inc (MNI). The companies also made a cross-agreement not to assert their DMR patents in the future. The company has previously licensed...

The Russian national standards body, the Russian Federal Agency on Technical Regulating and Metrology, has signed an historic Memorandum of Understanding (MoU) with ASTM International, originally known as the American Society for Testing and Materials. The goals of the MoU are to remove technical barriers in economic and trade...

The recent ARMMS RF & Microwave Society two-day conference, held in Steventon, Oxfordshire, UK, was well attended, lively and productive. It featured speakers from industry and academia and covered a wide range of topics including synthetic aperture radar, RFID, geodetic grade antenna design, waveguide horn design, interference measurements, filter...

Published October 17, 2007 You be the expert: The responses to the September Question of the Month are below. Turki Aommran submitted the September question of the month: Dear Harlan, I have designed microwave filters with Agilent ADS and the simulation results were perfect, but I have run into...

Most radar warning (RW), electronic countermeasures (ECM) and electronic intelligence (ELINT) systems employ instantaneous frequency measurement (IFM) to identify threats, map the electronic battlefield and eventually implement deceptive countermeasures. In its development of systems in this sector Elisra has made advances with the introduction of its Digital Instantaneous Frequency...
