Abstract

Perkembangan penguat kuasa jalur lebar adalah penting untuk teknologi radio pada masa depan. Penguat kuasa jalur lebar konvensional mempunyai produk gandaan-lebar jalur lebar yang terbatas berdasarkan transistor yang digunakan. Penguat teragih mampu menangani masalah ini melalui gabungan kuasa output daripada pelbagai transistor. Walau bagaimanapun, penguat kuasa jalur lebar konvensional juga mempunyai jalur lebar yang terbatas. Tambahan peranti yang melebihi jumlah optimum akan meningkatkan get dan mengecilkan ‘drain line’, dan seterusnya akan mengurangkan prestasi kuasa. The development of broadband power amplifier is critical for future radio technology. Conventional broadband power amplifier has gain-bandwidth product limitation based on transistor used. Distributed amplifier (DA) overcomes this limitation by combining output power from several transistors in additive fashion. However, conventional distributed amplifier has limitation in bandwidth as well. Adding devices beyond optimum number will increase gate and drain line attenuation and will degrade the power performance.
