Abstract
A reconfigurable radio frequency circuit is configurable to a first mode when first and second radio frequency signals are within a first frequency band, and to a second mode for use when the first but not the second signal is in the first band. A first signal divider operating in the first band provides a first signal division ratio in the first mode and a second ratio in the second mode. In the first mode, a first output of the signal divider is connected by a first switch to a first receiver and the second output is connected by a second switch to a second receiver. In the second mode, the first output is connected by the first switch to the first receiver and a second divider operating in a second band is connected by the second switch to the second receiver.
