Abstract
A high-speed digital transmitter for wireless communication systems includes a plurality of transmitter chain circuits configured to respectively receive incoming component signals having a first frequency and to produce outgoing transmission signals having a second frequency greater than the first frequency in a first domain. In some aspects, the incoming component signals are up-sampled to the second frequency using a plurality of streams processed concurrently at a predetermined sample rate over a predetermined number of interpolation filter stages in each of the plurality of transmitter chain circuits. The high-speed digital transmitter also includes a serializer configured to combine the outgoing transmission signals from the plurality of transmitter chain circuits into a serialized transmission signal having a third frequency greater than the second frequency in a second domain different from the first domain.
