Just announced by specialist distributor, Admiral Microwaves, is a range of millimeter wave switches manufactured by the world class manufacturer, Herley. The Series 90 switches are designed for defence and aerospace applications, and also suit a growing range of devices in the medical and scientific equipment sectors.

Finisar Corporation today announced availability of the industry’s only transmitter and receiver optical subassembly pairs (TOSA/ROSA) for the IEEE 10GBASE-LRM standard using Fabry-Perot lasers and PIN detectors. Several innovations introduced with these devices extend performance, conserve power, and expand control. Demonstrations will be held in Finisar’s booth #17048 at ECOC, September 17-19, 2007.

A new version of Yokogawa’s curve-tracer software for semiconductor testing has been introduced for the company’s GS610 source measure unit. Designed to carry out voltage/current analysis on two-lead or three-lead components including discrete semiconductors, integrated circuits and optoelectronic components, the new PC-based software works in conjunction with the USB-connected GS610 to enable source and sink operations at up to 100 V at 0.5 ...

Linear Technology Corporation annonce le LT3688, un régulateur à découpage, abaisseur, sortie double 800 mA, 36 V en entrée, avec deux minuteries de réinitialisation à la mise en marche et une minuterie de chien de garde. La gamme de tensions d’entrée du LT3688, de 3,8 V à 36 V, le rend idéal dans les conditions de rupture de charge et de démarrage à froid que l'on rencontre communément dans les applications de l'automobile. Ses de...

Linear Technology annonce le LT3970, un régulateur à découpage, abaisseur, 350 mA, 40 V, avec diodes élévatrice et de roue libre. Le fonctionnement en Burst Modeâ maintient le courant de repos inférieur à 2,5 µA en l’absence de charge. Le LT3970 fonctionne à partir d'une gamme de tensions d’entrée de 4,2 V à 40 V, ce qui le rend idéal dans les applications industrielles et de l'automobile. Son commutateur interne de 550 mA peut ...

Linear Technology has announced the LT3497, a dual, full- featured, step-up DC/DC Converter designed to drive up to 12 white LEDs from a Li-Ion input. Its high efficiency, fixed frequency operation ensures uniform LED brightness, low noise and maximum battery life, and the on-chip schottky diodes eliminate both the added cost and space of external diodes. True Color PWM dimming enables dimming ranges of up to 250:1 without any color shift of the ...

Linear Technology Corporation announces the LT3487, a dual channel (boost/inverter), 2MHz DC/DC converter with output disconnect. Its internal 750mA/900mA 30V switches can deliver up to 45mA at 15V and 90mA at -8V from a single Li-Ion cell, providing bias for the latest generation of CCD (Charge-Coupled Device) imagers. Its input voltage range of 2.3V to 16V enables inputs that range from Li-Ion to multiple cell alkaline/NiMH batteries. Switching...

Linear Technology has announced new wider temperature range versions of its LT1763 and LT1764A high current, low noise linear regulators. The new MP grade features operation from -55°C to +125°C for a wide range of applications including avionics, military, industrial, RF and telecom.

Linear Technology has announced the LT3970, a 350mA, 40V step-down switching regulator with integrated boost and catch diodes. Its Burst Mode operation keeps quiescent current under 2.5µA in no load standby conditions. The LT3970's 4.2V to 40V input voltage range makes it ideal for automotive and industrial applications. Its internal 550mA switch can deliver up to 350mA of continuous output current to voltages as low as 1.21V. The LT3970's Burst...

The A4983 from Allegro MicroSystems Europe is a compact DMOS microstepping motor driver IC with built-in translator circuitry for easy operation. The new device combines an easy-to-use step and direction interface with a high output capability of up to 35 V and ±2 A and high-resolution microstepping control. It is designed for the PWM (pulse-width modulation) control of bipolar stepper motors in full-, half-, quarter-, eighth, and sixteenth-step...
