Pada artikel ini dibahas mengenai pengaruh Mole fraction (x) dan Profil germanium pada basis SiGe HBT terhadap unjuk kerja Frekuensi dan Noise Figure (Fn) devais. Model parameter HBT SiGe ditentukan AE0,25 10 m2, WE10 nm, WB 40 nm, WC 350 nm, NE1021cm-3, dan NB 10 19 cm-3.Dari hasil analisa dapat disimpulkan bahwa profil Ge segiempat dengan mole fraction (x) 0.05 menghasilkan current gain dc (βdc), fT dan fmaks terbesar yaitu 149, 109 GHz ...

We propose a simple design of 1×3 optical power splitter which uses gallium nitride (GaN) on sapphire. The design consists of widely used large cross section input rib waveguide, a rectangular multimode interference (MMI) structure, and three-branch rib waveguides. The MMI structure is selected since their attractive performances, such as compactness, low excess loss, wide bandwidth and ease to fabricate. The power splitter is designed for the third telecommunication window, i.e., l = 1.55 µm. ...
