摘要： An adjustable mixer is disclosed that is capable of operating in different modes in order to satisfy the mixing requirement of multiple radio access technologies (RATs). The adjustable mixer includes a LO signal generating portion and a mixing portion. Depending on the mixing requirements of the RAT, the adjustable mixer can operate in any one of multiple modes, each mode having a specific configuration for the LO signal generating portion and the mixing portion. The LO signal generating portion generates a LO signal having a particular duty cycle, depending on the selected mode, for use by the mixing portion. The mixing portion has an adjustable circuit configuration that can be dynamically reconfigured based on the selected mode, and which allows the mixing portion to successfully mix received signals using the corresponding LO signals generated by the LO signal generating portion.
