Consumers have an unquenchable demand for higher video, data, and voice bandwidths through the cable, satellite, and terrestrial conduits. For the next evolutionary step, consumers will want more bandwidth at a lower cost. To meet this challenge, OEM designers will need to offer communications equipment that supports higher capacity at a lower solution cost. Modern wireless radio transmitter designs encompass real-intermediate-frequency (IF) transmitters, complex-IF transmitters, and zero-IF transmitters. At present, these transmitters continue to shuffle data through analog paths.
