(Invited) An Ultra-Low Insertion Loss T/R switch fully integrated with 802.11b/g/n transceiver in 90nm CMOS

An Ultra Low Insertion loss T/R switch fully integrated with 802.11 b/g/n direct conversion transceiver front end in 90 nm CMOS. The receiver achieves 3.6 dB NF at 2.4 GHz. The T/R switch has been designed and tested and has 0.3 dB insertion loss in the transmit mode and adds 0.1 dB of NF in the receive mode while occupying 0.02 mm2 of the die area.
