Patent ID: 8416758

Claim:
A reconfigurable radio frequency circuit for use in a wireless communications terminal, the circuit comprising: a receiver for receiving at least first and second radio frequency signals; a first signal divider for dividing signals in a first frequency band, the first signal divider being arranged to divide signals between at least a first divider output and a second divider output; a second signal divider for dividing signals in a second frequency band, the second signal divider being arranged to divide signals between at least a third divider output and a fourth divider output; a first radio frequency switch for connecting the first divider output to a first switch output for connection to a first receiver chain for receiving the first radio frequency signal in a first and a second mode, the circuit being configurable to the first mode for use when the first and second radio frequency signals are within the first frequency band, and being configurable to the second mode for use when the first radio frequency signal is within the first frequency band and the second radio frequency signal is within the second frequency band, different from the first frequency band; and a second radio frequency switch for connecting the second divider output to a second switch output in the first mode and to connect the fourth divider output to the second switch output in the second mode, the second switch output being for connection to a second receiver chain for receiving the second radio frequency signal, wherein the first signal divider is configured with a signal division ratio and is controllable, in the first mode, to a first state in which a first signal division ratio is set between the first and second divider outputs, and in the second mode, to a second state in which a second signal division ratio, different from the first signal division ratio, is set between the first and second divider outputs.
