Abstract
An ultra wideband direct sequence code division multiple access (UWB DS-CDMA) () transmitter is provided. It includes a first multiplier () receiving two input signals, where the input signals are selected from a multi-level code signal (), a transmit data signal (), and a radio frequency (RF) center frequency signal (), and responsive to the two input signals, generating a combined signal (). Further included is a network () receiving a code-clock signal () aligned with the multi-level signal (), multiplying the frequency of the code-clock signal () by a factor, and responsive thereto, producing the RF center frequency signal (). Also provided is a second multiplier () receiving the combined signal () and the other of the input signals (), and responsive thereto, generating an output signal ().
