1. A single-die integrated circuit for switching among a plurality of transmission ports and a plurality of received reports, comprising:

  • a transmitter switching section having a plurality of transmission ports, said transmitter switching section operable to switch a selected one of the plurality of transmission ports to a transmission node wherein, for each transmission port, the transmission switching section includes a plurality of FETs having current paths coupled in series with each other and operable to couple the transmission port to the transmission node, wherein a first one of the FETs proximate the respective transmission port has a current path with a first end coupled to the transmission port and a gate;

    a first feed-forward capacitor coupled between said first end of said current path and said gate of said first one of the FETs; and

    a receiver switching section having a plurality of received ports, said receiver switching section operable to switch a selected one of the plurality of received reports to the transmission node.
