| Summary: | 碩士 === 國立交通大學 === 電信工程研究所 === 103 === In this thesis, we use the PIN diodes to design a SP4T RF switch. Use the PIN diode model at RF to design a SPST RF switch, and then combine the four SPSTs into a SP4T RF switch. In practice, we will connect an antenna to each arm of the SP4T.Originally, it has only four beams in this structure, but as we combine those two nearby beams, there will be new directions of polarization between each two passing arms. The concept can reduce the amount of components and the PCB size.
