Patent ID: 8892063

Claim:
Circuitry comprising: a first multi-mode multi-band quadrature radio frequency (RF) power amplifier (PA) coupled to multi-mode multi-band alpha switching circuitry via a single alpha PA output, the multi-mode multi-band alpha switching circuitry comprising: a first alpha switching device comprising a plurality of switching elements coupled in series, the first alpha switching device coupled between the single alpha PA output and a first alpha non-linear mode output, wherein the first alpha non-linear mode output is associated with a first non-linear mode RF communications band; and a plurality of alpha switching devices, each of the plurality of alpha switching devices comprising a plurality of switching elements coupled in series, wherein each one of the plurality of alpha switching devices are coupled between the single alpha PA output and a corresponding one of a plurality of alpha linear mode outputs, such that each of the plurality of alpha linear mode outputs is associated with a corresponding one of a first plurality of linear mode RF communications bands.
