1. A Radio Frequency (RF) switch core comprising:

  • a first RF switch coupled in series between an upstream RF node and a downstream RF node, wherein the first RF switch comprises a first series connected plurality of transistors, further wherein each of the transistors of the first series connected plurality of transistors includes a first gate control voltage and a first body control voltage, further wherein the first body control voltage is positively biased higher than the first gate control voltage during an ON state of the first RF switch; and

    a second RF switch coupling the downstream RF node to ground, wherein the second RF switch comprises a second series connected plurality of transistors, further wherein each of the transistors of the second series connected plurality of transistors includes a second gate control voltage and a second body control voltage, further wherein the second body control voltage is positively biased during an ON state of the second RF switch.
