The comprehensive search engine on the AmpliTech website has been significantly revamped to not only allow for searches based on particular specifications, but to offer results that are closest to the entered parameters (within certain ranges) if a search by the exact specifications yields no matches. In addition, searching for a particular model number (in lieu of a search by specifications) has been made easier due to the ability to search for partials in case the customer doesn’t have the entire exact model number handy. More versatility has also been added by allowing searches just by using either a Start OR Stop frequency as opposed to both. For example, the user can simply enter 10 GHz for the Start frequency and leave the Stop frequency blank to see all models whose bandwidth starts at 10 GHz or higher.
Richardson Electronics announced the launch of a new business group, Power & Microwave Technologies (“PMT”). The PMT group encompasses Richardson Electronics’ existing Electron Device Group (“EDG”) and adds new technologies and engineered solutions for the power conversion and RF and microwave markets.
