Pseudomorphic high electron mobility transistors (PHEMT) have shown excellent microwave and noise performance and are very attractive for millimeter-wave and optoelectronic applications. The complete characterization of these devices, in terms of noise and scattering parameters, is necessary for computer-aided design (CAD) of monolithic microwave integrated circuits (MMIC) or optoelectronic...

The development of 3G services is requiring a constant increase in network capacity from the mobile operator. Dense access microwave networks, in terms of links per square kilometer and spectrum occupancy, are needed to connect UMTS nodes to the core network. Any introduction of a new link or any...

Analysis performed with traditional electromagnetic-field software might give a good sense of the operation of a microwave component from the perspective of pure electromagnetics under ideal conditions. Real-world operating conditions are not ideal, however, and the physical phenomena that affect a component’s performance often go beyond electromagnetics alone—effects from...

Most of today’s wireless applications call for a reduction in the physical size and an increase in the functionality of RF and microwave components, forcing designers to adopt a host of new materials and structures. These densely packed circuits present a number of engineering challenges from increased electromagnetic coupling...

The growing trend toward the use of smaller components in high-end microwave applications is being driven fervently by end-user demand for easier mobility and serviceability of equipment. Within the military realm especially, tactical agility in the field correlates directly to the use of certain types of equipment that are...

Broadband, Microwave and Wireless Components “Click to Quote” and “Click to Buy” are new features of the newly updated Aeroflex/Inmet web site. The site now allows a user to obtain a quote for any one of the listed products simply by clicking on the quote button pictured next to...

Laird Technologies , a designer and manufacturer of antenna solutions, electromagnetic interference (EMI) shielding products, telematics and thermal management solutions, announced the acquisition of Steward Inc. and its subsidiaries for $52.5 M. Steward is a provider of ferrite-based products that are used to remove unwanted EMI “noise” and other...

The RF to Light 100 rose 1.4% last week, YTD +15% at 2492 - close to the record high of 2502 in May 06. At that time the average P/E ratio stood at 78, now at 29. Total 3Q financials of 50 corporations: Revenues up, free cash flow up,...

The continuing increase in demand in Europe for instrument rental and leasing, which is currently estimated to be around €58 to €60 M, has led Electro Rent Europe to expand its operation into the UK. Having launched its European operations in January this year with offices in Mechelen, Belgium,...

The Dutch Ministry of Defense has awarded EADS , together with its partners – Oerlikon Contraves and Kongsberg – the contract to supply technical systems for battle management command, control, communication, computers and information (BMC4I), part of the Netherlands Future Ground Based Air Defense (FGBAD NL). The contract was...
