Kerja ini menangani kecekapan besar dan potensi kelinearan transistor mobiliti elektron tinggi (HEMT) AlGaN/GaN yang dioptimumkan dalam penguat stesen pangkalan linear Doherty konvensional pada 2.7 GHz. Disokong oleh simulasi peranti fizikal, kerja ini menghuraikan lebih lanjut tentang penggunaan AlGaN/GaN HEMT dalam mod suis arus berkelajuan tinggi kelas-D (CMCD)/kelas-S MMIC untuk kadar data sehingga 8 Gbit/s bersamaan dengan 2 GHz RF-operasi. Keperluan peranti untuk operasi mod suis diperoleh dan disahkan oleh keputusan MMIC dalam operasi kelas-S dan kelas-D. Untuk pengetahuan penulis, ini adalah kali pertama operasi RF mod suis digital setara 2 GHz ditunjukkan dengan HEMT GaN dengan kecekapan tinggi.

Abstract: This work addresses the enormous efficiency and linearity potential of optimized AlGaN/GaN high-electron mobility transistors (HEMT) in conventional Doherty linear base-station amplifiers at 2.7 GHz. Supported by physical device simulation, the work further elaborates on the use of AlGaN/GaN HEMTs in high-speed current-switch-mode class-D (CMCD)/class-S MMICs for data rates of up to 8 Gbit/s equivalent to 2 GHz RF-operation. The device needs for switch-mode operation are derived and verified by MMIC results in class-S and class-D operation. To the authors' knowledge, this is the first time 2 GHz-equivalent digital-switch-mode RF-operation is demonstrated with GaN HEMTs with high efficiency.
