Abstract
Methods and systems for a baseband cross-bar may comprise receiving one or more radio frequency (RF) signals in a wireless communication device via antennas coupled to a plurality of receiver paths in the wireless device. The received RF signals may be converted to baseband frequencies. One or more of the down-converted signals may be coupled to receiver paths utilizing a baseband cross-bar. The baseband cross-bar may comprise a plurality of switches, which may comprise CMOS transistors. In-phase and quadrature signals may be processed in the one or more of the plurality of receiver paths. The one or more RF signals comprise cellular signals and/or global navigation satellite signals. A single-ended received RF signal may be converted to a differential signal in one or more of the plurality of receiver paths. The baseband cross-bar may be controlled utilizing a reduced instruction set computing (RISC) processor.
