Low insertion loss and high linearity PHEMT SPDT and SP3T switch ICs for WLAN 802.11 a/b/g applications

GaAs SPDT and SP3T antenna switch ICs for IEEE 802.11 a/b/g applications are developed. By using advanced Skyworks PHEMT technologies, it is possible to achieve an insertion loss as low as 0.55 dB for SPDT switch, 0.5 dB lower than any previously reported DC-6 GHz band switch, and high linearity with 55 dBm input IP3 and a high isolation over 20 dB at 3 V… CONTINUE READING
