| Abstract |
This paper describes the design and the simulation of a single pole double throw(SPDT) FET switch for wireless LAN(IEEE802.11a & IEEE802.11b) applications using drain impedance transformation network with Microstrip transmission line. At the receiving path insertion losses were from 0.8[dB] to 1.462[dB] between 2[GHz] and 4[GHz], from 1.26[dB] to 2.3[dB] between 4.7[GHz] and 6.7[GHz] and the isolations were under 30[dB] between 2[GHz] and 6.7[GHz]. At the transmitting path insertion loss were from 1.18[dB] to 2.87[dB] between 2[GHz] and 4[GHz], from 0.625[dB] to 1.2[dB] between 4.7[GHz] and 6.7[GHz] and the isolations were under 30[dB] between 2[GHz] and 6.7[GHz]. |
