ABSTRACT:
A programmable hybrid transmitter includes a baseband processing module, an up-conversion module, and a power amplifier circuit. The baseband processing module is coupled to convert outbound data into a complex signal when the programmable hybrid transmitter is in a first mode and to convert the outbound data into a normalized complex signal, offset information, and/or transmit property information when the programmable hybrid transmitter is in a second mode. The up-conversion module is coupled to mix the complex signal with a local oscillation to produce an up-converted signal when the programmable hybrid transmitter is in the first mode and to mix the normalized complex signal with the local oscillation based on the offset information to produce a normalized up-converted signal when the programmable hybrid transmitter is in the second mode. The power amplifier circuit is coupled to amplify the up-converted signal to produce an outbound RF signal when the programmable hybrid transmitter is in the first mode and to amplify the normalized up-converted signal based on the transmit property information to produce the outbound RF signal when the programmable hybrid transmitter is in the second mode.
