Abstract
An integrated RF front-end architecture is disclosed. Such an integrated RF front-end architecture includes a multi-tap balun, a low noise amplifier and a power amplifier core. The multi-tap balun includes a single-ended primary winding and a symmetrical multi-tap secondary winding, wherein the single-ended primary winding is operably coupled to an antenna. The low noise amplifier is coupled to a first set of taps of the symmetrical multi-tap secondary winding. The power amplifier core is coupled to a second set of taps of the symmetrical multi-tap secondary winding and can be a two stage amplifier having a driver stage and an output stage. The multi-tap balun, low noise amplifier and power amplifier core can be on-chip components or can be fabricated to be discrete components on a printed circuit board.
