Uncertain Times for DefenseWill OpenRFM Shake Up the Microwave Industry?
By Barry Manz

Throughout the history of the RF and microwave industry there has never been a form factor standardizing the electromechanical, software, control plane, and thermal interfaces used by integrated microwave assemblies (IMAs) employed in defense systems. Rather, every system has been built to meet the requirements of a specific system, which may be but probably isn’t compatible with any other system. It’s simply the way the industry has always responded to requests from subcontractors that in turn must meet the physical, electrical, and RF requirements of prime contractors. Read More...

MILMEGA Ltd presented with Queen’s Award for Innovation 2012
Ryde, Isle of Wight, UK – October 3, 2012

MILMEGA Ltd, was presented with the Queen’s Award for Enterprise in Innovation for developing amplifiers, based on a novel design methodology, using gallium nitride-based transistor technology, which has brought the Company significant, global, commercial success.

Her majesty’s Lord Lieutenant Major General Martin White CB CBE JP presented the Award to the Company on behalf of Her Majesty The Queen at a ceremony held at the Priory Bay Hotel in Seaview on Friday 28th September.

The ceremony was attended by the Company’s staff and partners as well as local suppliers together with dignitaries from the Isle of Wight including John Owen, Chairman of the Chamber of Commerce, Steve Beynon, Chief Executive of the Isle of Wight Council, Susan Scoccia, Chairman of the Isle of Wight Council and David Woodward, Mayor of Ryde.

Graeme Goodall, MILMEGA’s FD received a crystal bowl engraved with the Queens Award emblem on behalf of the Company’s staff together with a ceremonial Grant of Appointment and thanked both those who work at MILMEGA and with MILMEGA for their contributions to this achievement.

Graeme Goodall, FD said “The Award says a lot about the skills and abilities of those who work at and with MILMEGA in achieving sustained global success in the design and manufacture of highly innovative, market leading, amplifier products. I am also pleased that this Award recognises and promotes, not only our innovative designs but also the values of quality and customer service that are important to us as a Company.”

The prestigious Queen’s Award for Innovation is awarded to businesses in the UK to recognise outstanding innovative achievements relative to their operational size. To win the Award, MILMEGA Ltd was required to demonstrate continuous innovation and development over a period of five years resulting in substantial improvement in the performance of the Company. In addition the Award is only made to organisations that can demonstrate a high level of corporate responsibility.

MILMEGA Ltd is a specialist designer and manufacturer of high power, solid state broadband RF and microwave amplifiers. The Company’s 25-year history is supported by a strong reputation for the quality and technical innovation of its products.

MILMEGA’s products are used throughout the world in EMC testing, defence, communications and high-energy physics. The proliferation of electronic systems in products such as cars, mobiles, notebooks, televisions, medical equipment, aircraft and other products has led to increasingly serious problems with electromagnetic interference. EMC testing evaluates the susceptibility of electronic products to electromagnetic emissions by irradiating them with signals generated by high-powered amplifiers. Manufacturers, therefore, test these electronic products for electromagnetic compatibility and susceptibility using broadband high power amplifiers.

Established in 1987, MILMEGA Ltd employs 31 design, manufacturing and support staff at its factory in Ryde, Isle of Wight. Following a MBO in 2004 the Company has grown significantly by investing heavily in new product design and by expanding its overseas markets most notably in the Far East.

The Company was acquired in January 2012 by Teseq Ltd, a UK subsidiary of Teseq Holding AG a large global EMC group based in Switzerland.

Communications & Power Industries Nets $5 Million for satcom SSPAs and TWTAs

Communications & Power Industries has received initial orders totaling more than $5 million from a prime contractor for high-power, Ka-band satellite communications amplifiers to be used in a U.S. military communications program intended to provide worldwide communications connectivity to tactically deployed forces. CPI will provide both solid-state and vacuum electron device products for the program, including solid-state power amplifiers with internal block upconverters and CPI's SuperLinear traveling wave tube amplifiers (TWTAs).  Work on this program will be performed across several of CPI's divisions and is expected to continue for the next five years.

Hittite invests $5 million in R&D and operations centers in Ireland

Hittite Microwave says it will create 30 new jobs in Cork (19 in R&D and 11 at a new international operations center) in a project supported by the Irish government through Industrial Development Agency Ireland. Products that will be designed at the new Cork R&D facility will be components for use in telecom and sensor systems. The international operations center will manage non-US business in closer proximity to customers. A global supply chain and finance team will also be located in Cork. Hittite chose Cork in part because of its proximity to the semiconductor and integrated circuit design capabilities in Tyndall Institute, University College Cork, and Cork Institute of Technology.

Ex EW officer joins anti-smart meter parade

A retired 22-year veteran electronic warfare officer says the City of Kelowna, British Columbia, should put its proposed sale of its share in electrical utilities to referendum, according to an article at Castanet.net. Resident Jerry Flynn, a 77-year-old former officer with the Communications Research Branch of the Royal Canadian Navy, says he fears the proposed sale of the city’s electrical utility rights will ultimately result in energy provider FortisBC installing smart meters in the city without public input, something Flynn says will put everyone’s health at risk. Flynn joins the growing chorus of people in the U.S., Canada, and elsewhere, who believe that, as the meters use RF energy for communication, they can lead to various health problems. The BC government’s controversial rollout of smart meters through public utility BC Hydro, as mandated by the 2010 Clean Energy Act, has provoked opposition among those concerned with not only potential health effects but with security, privacy, billing, and economic issues.

The Greening of the Microwave…

A coalition including Whirlpool and Plextek are leading a new project investigating high-efficiency electronic cooking systems in conjunction with ENIAC Joint Undertaking, an EU-backed program. The goal is to reduce household energy use by 25%. Plextek has completed the first stage of the project: investigating the way RF energy is used in everyday appliances. The company is now constructing prototype low-energy microwave ovens for testing, having focused on developing more efficient components such as semiconductor process technologies, improved thermal management systems, and intelligent electromagnetic field controllers, that can then be integrated into a new system. Other companies involved include NXP, Comheat, Bergh Hybrid Circuits and the universities of Warsaw, Chalmers, Padova and TU Delft. Source: businessgreen.com
