Abstract(in English) | High efficiency HEMTs for high power linear amplifiers with single biasing supply are demonstrated. In these devices, high reliability Platinum buried gates have been adopted to obtain higher Shottoky barrier height of 0.9 eV for single voltage supply. Double-Hetero structure has been adopted for linearity and large gain. GaAs/InGaAs/GaAs superlattice channel has also been adopted for higher electron mobility of 6300 cm^2/Vs for high sheet carrier concentration of 3.6×10<12> cm^<-2>. By using these technologies, high output power of 1.5 W and high power and efficiency of 41% are obtained for 1.5GHz Personal Digital Cellular(PDC) conditions with +3 V single voltage supply. |
