In this report, two major items are covered. One is the design, simulation and measurement results of a k-band PHEMT MMIC frequency multiplier using CIC PML GaAs foundry. The second result is to develop a new analysis method for a coupled active multiplier antenna array. This method combines harmonic-balance method and weakly couple oscillator dynamic theory to give a well prediction of the second harmonic output power, locking bandwidth, matching condition and phase distribution between array elements. An X-band active multiplier antenna array is fabricated and its measurement results shown in good agreement with simulation results.application/pdf247057 bytesapplication/pdfzh-TW國立臺灣大學電信工程學研究所倍頻器自振倍頻器主動天線陣列multiplierself-oscillating multiplieractive antenna arrayreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/20237/1/892219E002043.pdf
