Abstract

An Ultra Low Insertion loss T/R switch fully integrated with 802.11b/g/n direct conversion transceiver front end in 90nm CMOS. The receiver achieves 3.6dB NF at 2.4GHz. The T/R switch has been designed and tested and has 0.3dB insertion loss in the transmit mode and adds 0.1dB of NF in the receive mode while occupying 0.02 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> of the die area.
