In the first part of this thesis, each individual circuit of the RF front-end, integration of the RF front-end, and measurement of the RF front-end and each individual circuit are described. The conversion loss of the RF front-end is about 9.3 to 13.3 dB and the RF output power is about 3.2 to 4.4 dBm.The whole circuits are integrated with CPW on an Al2O3 substrate with a dielectric constant of 9.8, a thickness of 15 mil. In the second part of this thesis, the design and measurement of reflective phase shifter are presented. The maximal phase shift is larger than 120 degree. A unit circuit of phased array is implemented and measured, which includes an analog phase shifter, a coupler, and a phase compensation transmission line. The mainbeam of the array can be switched between 35 to 60 degree in vertical direction. The whole circuits are fabricated with microstrip line on a RO4003 substrate with a dielectric constant of 3.38, a thickness of 20 mil. Chi-Yang Chang 張志揚 2006 學位論文 ; thesis 38 zh-TW |
