| Summary: | 碩士 === 元智大學 === 通訊工程學系 === 94 === In this paper, we designed a power amplifier and high linearity mixer by monolithic microwave integrated circuit (MMIC) technology. The specifications of designed power amplifier are fulfilled the requirements of IEEE 802.16-2004 WiMAX standard. The power amplifier is implemented with WIN 0.15μm pHEMT and the high linearity mixer is implemented with TSMC 0.18μm CMOS processes.
The simulation result of the power amplifier, gain is 23.003 dB, output at the 1-dB gain compression point is 30 dBm, power added efficiency is 31.4%,output third order intercept point is 39.8 dBm, tuning range is greater than 30dB. The chip size of the circuit is 1×2 mm2.
The measurement result of the mixer, drive on the high gain mode, conversion gain is 8.4 dB, output at the 1-dB gain compression point is -7 dBm, output third order intercept point is 2 dBm, port to port signal isolations are greater than 30dB. Drive on the low gain mode, conversion gain is 1.4 dB, output at the 1-dB gain compression point is -6.6 dBm, output third order intercept point is 5 dBm, port to port signal isolations are greater than 25dB.The chip size of the circuit is 0.96×0.79 mm2.
