Summary: | 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. |
