Signal receiver
First Claim
1. A signal receiver comprisinga first synthesizer configured to generate an oscillating output;
- a first mixer configured to mix its first input with its second input associated with said oscillating output of said first synthesizer into an output;
a first splitter configured to split its input associated with said output of said first mixer into a first output and a second output;
a first switch matrix configured to switch its first input associated with said first output of said first splitter into a first output;
a second switch matrix configured to switch its first input associated with said second output of said first splitter into a first output;
a second synthesizer configured to generate an oscillating output;
a second mixer configured to mix its first input associated with said first output of said first switch matrix with its second input associated with said oscillating output of said second synthesizer into an output;
a third synthesizer configured to generate an oscillating output; and
a third mixer configured to mix its first input associated with said first output of said second switch matrix with its second input associated with said oscillating output of said third synthesizer into an output.

Abstract
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.
