Abstract:
1. A communications device comprising: an In-phase (I) power amplifier configured to generate an I amplified signal; a Quadrature (Q) power amplifier configured to generate a Q amplified signal; a programmable I driver coupled upstream of said I power amplifier; a programmable Q driver coupled upstream of said Q power amplifier; an I digital-to-analog converter (DAC) configured to generate an I signal; a Q DAC configured to generate a Q signal; an I power supply circuit coupled to said I power amplifier and to said I DAC and configured to cause said I power amplifier to modulate an I carrier signal into the I amplified signal based upon the I signal; a Q power supply circuit coupled to said Q power amplifier and to said Q DAC and configured to cause said Q power amplifier to modulate a Q carrier signal into the Q amplified signal based upon the Q signal; and at least one antenna coupled to said I and Q power amplifiers.
