| Summary: | Broadband technology has rapidly become an established, global commodity required by high percentage of the population. Worldwide Interoperability for Microwave Access (WiMAX) using the Orthogonal Frequency Division Multiple Access (OFDMA) modulation to suit multi-path environments that gives network operators higher throughput and capacity. Without power amplifier (PA), the signal will attenuate itself through the transmission line and resulting receiver can’t construct the original signal information. In order to overcome the problem, PA with the ability to achieved high gain and high output power is placed in front of the transmitter to boost the signal high enough to ensure the receiver get all the signal information that it should received and loss can be avoided. This project is basically is to design PA that will operate in the frequency range of 3.3 GHz to 3.8 GHz which licenses frequency allocation for IEEE 802.16 or WiMAX. The aim for this project is to get gain, S21 more than 12 dB by comparing several design technique of the PA such as balanced amplifier and feedback amplifier in order to get the best performance of PA after the analysis between the designs. The implementation of the design is based on the AWR Microwave Office software used to perform simulation of the power amplifier design. Analysis will be done by comparing the results of calculations and simulation and between the design techniques. At the end of this project, it is shown that the results nearly the same for both calculation and simulation and feedback amplifier gives the best result of gain, S21 which is about 15.60 dB in average. |
