摘要： 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.

摘要： Techniques for providing an efficient interface between a mixer block and a transconductance (Gm) block. In an exemplary embodiment, the output currents of at least two unit cells of the transconductance block are conductively coupled together, and coupled to the mixer block using a single conductive path. For a differential signal, the conductive path may include two conductive leads. Within the mixer block, the single conductive path may be fanned out to at least two unit cells of the mixer block. At least one Gm unit cell may be selectively enabled or disabled to control the gain setting of the mixer-transconductance block. The techniques may further be applied to transceiver architectures supporting in-phase and quadrature mixing, as well as multi-mode and/or multi-band operation.
