| Abstract: | With the RF power and working band increase in communication system,high power capacity,high isolation,low insertion loss,short response time of the RF switch is especially important.The theory of SPDT is introduced briefly,the key application of PIN diode is analyzed under the high power capacity and a 1to4 RF switch which working at 200MHz ~ 500MHz,loss<0.7dB,isolation>70dB,VSWR<1.5,Power 100W,response time<20μs is designed. |
