Summary:Techniques for using one or multiple downconverters to receive multiple transmissions sent on multiple carriers are disclosed. In an exemplary design, an apparatus includes first and second downconverters. The first downconverter downconverts a first radio frequency (RF) signal when it is selected. The second downconverter downconverts a second RF signal when it is selected. Each of the first and second RF signals includes multiple transmissions sent on multiple carriers to a wireless device. The first downconverter is selected to perform downconversion for the multiple transmissions when at least one criterion is not met. The first and second downconverters are selected to perform downconversion for the multiple transmissions, based on different mixing frequencies, when the at least one criterion is met. The at least one criterion may relate to imbalance between the multiple carriers, received power of a received RF signal, etc.
