A signal receiver includes a first mixer configured to mix its first input with its second input associated with an oscillating output of a first synthesizer into an output; a first splitter configured to split its input associated with the output of the first mixer into a first output and a second output; a first switch matrix configured to switch its first input associated with the first output of the first splitter into a first output; a second switch matrix configured to switch its first input associated with the second output of the first splitter into a first output; a second mixer configured to mix its first input associated with the first output of the first switch matrix with its second input associated with an oscillating output of a second synthesizer into an output; and a third mixer configured to mix its first input associated with the first output of the second switch matrix with its second input associated with an oscillating output of a third synthesizer into an output.
