چکیده
|
This paper presents a design of radio frequency amplifier (rfa), which operates at 5.8 ghz frequency for wimax application. the rfa designed used t-matching network consisting of lump reactive elements, 3 db attenuator and microstrip line at the input and output impedance. the rfa developed in this project contribute a gain of 15.6 db with overall noise figure of 2.4 db. the overall measured bandwidth measures is 1.240 ghz with s parameters s11, s12 and s22 measured are -12.4 db, -25.5 db and -12.3 db respectively. the rfa used fet transistor epa018a from excelics semiconductor inc.
