We see from your search that you're looking for information on the term "Gallium arsenide", and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest. Let me be your guide.
Start with the news release Digital optocouplers have industrial specs from Avago Technologies, which we summarised at the time by saying "Wide temperature optocouplers are extremely reliable and ideal for use in applications that operate in harsh industrial environments". A few weeks before, we featured the news release IC receiver handles 4.5 to 10.5GHz frequency bands from Mimix Broadband: "The XR1011-QH integrates an image reject mixer, an LO buffer amplifier and a low-noise amplifier within a fully moulded 4 x 4mm QFN package".
In July 2007, we covered the news from Toshiba Electronics Europe concerning its TLP3082 - take a look at Photocouplers enhance white goods safety which says: "Power triac photocoupler has reinforced insulation and boasts 5kV isolation voltage for AC safety applications".
Take a look also at the news release from ON Semiconductor, Copper process upgrades passives performance, as well as Amp buffers wide-bandwidth applications from Mimix Broadband, and Broadband transmitter chip integrates more from Mimix Broadband.
