Drivers for GaAs FET Switches and Digital Attenuators

Introduction Many of M/A-COMs GaAs FET switches and digital attenuators cannot operate directly with simple TTL or CMOS logic, but instead require external circuits to provide appropriate control voltages. This application note, an update of M539, Drivers for GaAs FET MMIC Switches and Digital
