A new isolated Drive-by-Microwave (DBM) gate driver with a high-speed voltage monitoring for over current detection is proposed, which is composed of a 2.4GHz GaN/Si DBM transmitter, DBM receiver chip and compact isolated couplers in a low-cost printed circuit board. The fabricated DBM gate driver demonstrates a 200 Mbps isolated data transmission and a GaN power switching device's driving with a...
Silicon-on-sapphire (SOS) was invented in 1961 and as such is the first of the SOI technologies. Its original purpose was to provide radiation tolerant circuits for satellites and missiles. Now, SOS is ready to displace gallium arsenide (GaAs) as the technology of choice for RF communications in commercial applications. What are the reasons for this? In this paper, I will share what we have learned...
GaN FET technology is facilitating the development of a new level of high power solid state switching performance. FET switches are now obtaining RF power handling levels comparable and even exceeding conventional PIN and mechanical switches up thru microwave frequencies while still offering the traditional advantages common to GaAs switches.
