Abstract

An apparatus for implementing phase rotation at baseband frequency for transmit diversity may include a primary transmit signal path and a diversity transmit signal path. Both the primary transmit signal path and the diversity transmit signal path may receive a primary transmit signal. A signal selector within the diversity transmit signal path may perform phase rotation with respect to the primary transmit signal while the primary transmit signal is at a baseband frequency, thereby producing a diversity transmit signal.
