| Abstract: | A type of series-parallel single pole double throw(SPDT) switch with broadband and high isolation was designed and made up by utilizing several PIN diodes.First of all,the special PIN diode equivalent circuit models of open circuit and short circuit were set up.Then the circuit simulation and parameter optimization were carried out by using CAD software Serenade to get good results.In the end,the circuit plate-making plot and economically practical micro-strip switch were fabricated,and the qualification was reached by testing. |
