Patent ID: 7826554

Claim:
A digital transmitter comprising: an encoder for converting a magnitude signal received from a modem to a first 1-bit logic signal; a digital phase modulator (DPM) for modulating a carrier using a phase signal received from the modem to generate a second 1-bit logic signal; a digital upconverter (DUC) for upconverting the second 1-bit logic signal; a first-in first-out (FIFO) memory for storing the first 1-bit logic signal and aligning the magnitude signal processed by the encoder with the phase signal processed by the DPM and the DUC; a magnitude and phase combiner for combining angle information contained in the second 1-bit logic signal with magnitude information contained in the first 1-bit logic signal stored in the FIFO memory and outputting a combined signal; and a digital power amplifier (DPA) for generating a radio frequency (RF) signal based on the combined signal.
