InP Epitaxial Wafers beyond 2.0µm

Marktech Optoelectronics is now offering Indium Phosphide Epitaxial wafers up to 4 inches with wavelengths of 1.7µm 2.2µm and 2.6µm, ideally suited for high speed imaging, high speed HBT and HEMTs, APDs and analog-digital converter circuits. Applications using InP-based components can greatly exceed transmission rates in comparison to similar components structured on GaAs or SiGe based platforms.

Utilizing sophisticated MBE and MOCVD manufacturing processes in Epitaxial InP thin film growth, Marktech is now producing high reliability wafers on 2", 3" and 4" substrates. Demands continues to increase for higher transmission rate and longer wavelength components capable of exceeding today's commercially available products with speeds ranging up to 10Gbit/s. It is acknowledged that GaAs and SiGe based components have limitations in terms of speed. Devices based on an InP platform are capable of exceeding these transmission rate limitations, including the operating margin.

Due to the rapid increases in demand put on electronic communication equipment, it is vital to build communication systems that enable high speed and high volume signal processing. In order to process vast amounts of signals, wired communications such as fiber optics need to make continued advancements in time division multiplexing (TDM) and wavelength division multiplexing (WDM) capabilities. In wired fiber optic communications, TDM rather than WDM electronic circuits make it possible to ease system building allowing for downsizing of the communication system, and therefore the costs associated. The development of ultra high speed electronic devices is the key to possibilities for the future of these changes.

Applications include high resolution imaging arrays, high capacity wireless communications, high data rate optical fiber systems, thin film solar panels and sub millimeter-wave spectroscopy.

Biasi Develops ActivA Unique Boiler Range Biasi UK has developed ActivA, a new range of high efficiency A rated condensing boilers boasting a unique heat exchanger. The launch of ActivA is further testimony to the company's commitment to strengthen its position in the UK domestic gas boiler market. At the heart of ActivA is a newly developed pre-mix condensing heat exchanger that is manufactured in a corrosion resistant, pressure moulded aluminium. Its sectional construction means it can be easily adjusted for different boiler outputs and its 'multipass' design ensures very low resistance for both combustion and water passage. This unique heat exchanger carries a five year guarantee. Designed to provide outstanding heating performance at an affordable price for almost all types of domestic properties, the compact range boasts some of the smallest boilers available - at just 700mm high x 400 wide and only 290mm deep - thereby allowing installation in cupboards. As well a

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as
