| Summary: | 碩士 === 元智大學 === 電機工程研究所 === 89 === Power amplifier is the key component of wireless communication system, which is usually used in the RF transmitter. In this work we will study and implement the 5.25GHz and 5.8GHz power amplifier by monolithic microwave integrated circuit (MMIC) technology.The effect of second harmonic spurs for different kinds of output and interstage matching network are evaluated . The specification of the designed power amplifier are fulfilled the requirements of IEEE 802.11a standard，which uses OFDM modulation on the 5.7GHz ISM band.High linearity, low voltage (3.3V) MMIC power amplifiers have been implemented in this research .The nonlinear large signal model of InGaP/GaAs HBT is used to simulate and analyze the performance of designed circuits. The chip size of this power MMIC is about 1042μm×610μm. The output power is 23dBm while the input power is 2dBm; the circuit layout and processes are completed by local foundry service in Taiwan.
