Plessey Research Caswell
Caswell is a lost settlement in Greens Norton parish Northamptonshire, England, approximately north-west of Towcester, from Northampton and from Milton Keynes. It consists almost entirely of Caswell Park science and technology park, which has developed since the 1940s around a 19th-century farmhouse. Caswell House The farmhouse was built for the Duke of Grafton's estate around 1840, at the same time as another at Field Burcote, about a mile to the west. Both have three widely spaced bays with low-pitched hipped slate roofs and lower wings, and are formally arranged. At Caswell the building and its single-storey outbuildings, although much altered in the 20th century, are Grade II listed. Research establishment Foundation The concept of a research lab covering the Plessey company's interests in materials germinated in 1934 when its founders Allen George Clark and William O. Heyne were in charge. Another leading member of staff at this time was Geoffrey Gaut, who joined the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Northamptonshire
West Northamptonshire is a unitary authority area covering part of the ceremonial county of Northamptonshire, England, created in 2021. By far the largest settlement in West Northamptonshire is the county town of Northampton. Its other significant towns are Daventry, Brackley and Towcester; the rest of the area is predominantly agricultural villages though it has many lakes and small woodlands and is passed through by the West Coast Main Line and the M1 and M40 motorways, thus hosting a relatively high number of hospitality attractions as well as distribution centres as these are key English transport routes. Close to these is the leisure-use Grand Union Canal. The district has remains of a Roman town Bannaventa, with relics and finds in the main town museums, and its most notable landscape and the mansion is Althorp. History West Northamptonshire was formed on 1 April 2021 through the merger of the three non-metropolitan districts of Daventry, Northampton, and South North ...

Prince Philip, Duke Of Edinburgh
Prince Philip, Duke of Edinburgh (born Prince Philip of Greece and Denmark, later Philip Mountbatten; 10 June 1921 – 9 April 2021) was the husband of Queen Elizabeth II. As such, he served as the consort of the British monarch from Elizabeth's accession as queen on 6 February 1952 until his death in 2021, making him the longest-serving royal consort in history. Philip was born in Greece, into the Greek and Danish royal families; his family was exiled from the country when he was eighteen months old. After being educated in France, Germany, and the United Kingdom, he joined the Royal Navy in 1939, when he was 18 years old. In July 1939, he began corresponding with the 13-year-old Princess Elizabeth, the elder daughter and heir presumptive of King George VI. Philip had first met her in 1934. During the Second World War, he served with distinction in the British Mediterranean and Pacific fleets. In the summer of 1946, the King granted Philip permission to marry El ...

Monolithic Microwave Integrated Circuit
Monolithic microwave integrated circuit, or MMIC (sometimes pronounced "mimic"), is a type of integrated circuit (IC) device that operates at microwave frequencies (300 MHz to 300 GHz). These devices typically perform functions such as microwave mixing, power amplification, low-noise amplification, and high-frequency switching. Inputs and outputs on MMIC devices are frequently matched to a characteristic impedance of 50 ohms. This makes them easier to use, as cascading of MMICs does not then require an external matching network. Additionally, most microwave test equipment is designed to operate in a 50-ohm environment. MMICs are dimensionally small (from around 1 mm² to 10 mm²) and can be mass-produced, which has allowed the proliferation of high-frequency devices such as cellular phones. MMICs were originally fabricated using gallium arsenide (GaAs), a III-V compound semiconductor. It has two fundamental advantages over silicon (Si), the traditional mater ...

Field Effect Transistor
The field-effect transistor (FET) is a type of transistor that uses an electric field to control the flow of current in a semiconductor. FETs (JFETs or MOSFETs) are devices with three terminals: ''source'', ''gate'', and ''drain''. FETs control the flow of current by the application of a voltage to the gate, which in turn alters the conductivity between the drain and source. FETs are also known as unipolar transistors since they involve single-carrier-type operation. That is, FETs use either electrons (n-channel) or holes (p-channel) as charge carriers in their operation, but not both. Many different types of field effect transistors exist. Field effect transistors generally display very high input impedance at low frequencies. The most widely used field-effect transistor is the MOSFET (metal-oxide-semiconductor field-effect transistor). History The concept of a field-effect transistor (FET) was first patented by Austro-Hungarian physicist Julius Edgar Lilienfeld in 1925 an ...

Gallium Arsenide
Gallium arsenide (GaAs) is a III-V direct band gap semiconductor with a Zincblende (crystal structure), zinc blende crystal structure. Gallium arsenide is used in the manufacture of devices such as microwave frequency integrated circuits, monolithic microwave integrated circuits, infrared light-emitting diodes, laser diodes, solar cells and optical windows. GaAs is often used as a substrate material for the epitaxial growth of other III-V semiconductors, including indium gallium arsenide, aluminum gallium arsenide and others. Preparation and chemistry In the compound, gallium has a +3 oxidation state. Gallium arsenide single crystals can be prepared by three industrial processes: * The vertical gradient freeze (VGF) process. * Crystal growth using a horizontal zone furnace in the Bridgman-Stockbarger technique, in which gallium and arsenic vapors react, and free molecules deposit on a seed crystal at the cooler end of the furnace. * Liquid encapsulated Czochralski process, Czoch ...

GEC Marconi
Marconi Electronic Systems (MES), or GEC-Marconi as it was until 1998, was the defence arm of General Electric Company (GEC). It was demerged from GEC and bought by British Aerospace (BAe) on 30 November 1999 to form BAE Systems. GEC then renamed itself Marconi plc. MES exists today as BAE Systems Electronics Limited, a subsidiary of BAE Systems, but the assets were rearranged elsewhere within that company. MES-related businesses include BAE Systems Submarine Solutions, BAE Systems Surface Ships, BAE Systems Insyte and Selex ES (now a part of Leonardo S.p.A.). History MES represented the pinnacle of GEC's defence businesses which had a heritage of almost 100 years. Following GEC's acquisition of Marconi as part of English Electric in 1968, the Marconi brand was used for its defence businesses, e.g. Marconi Space & Defence Systems (MSDS), Marconi Underwater Systems Ltd (MUSL). GEC's history of military products dates back to World War I with its contribution to the war ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

General Electric Company
The General Electric Company (GEC) was a major British industrial conglomerate involved in consumer and defence electronics, communications, and engineering. The company was founded in 1886, was Britain's largest private employer with over 250,000 employees in the 1980s, and at its peak in the 1990s, made profits of over £1 billion a year. In June 1998, GEC sold its share of the joint venture GEC-Alsthom on the Paris stock exchange. In December 1999, GEC's defence arm, Marconi Electronic Systems, was sold to British Aerospace, forming BAE Systems. The rest of GEC, mainly telecommunications equipment manufacturing, continued as Marconi Communications. After buying several US telecoms manufacturers at the top of the market, losses following the bursting of the dot-com bubble in 2001 led to the restructuring in 2003 of Marconi plc into Marconi Corporation plc. In 2005, Ericsson acquired the bulk of that company. What was left of the business was renamed Telent. History ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
