Integrated wideband communication circuit

A communications circuit, comprising:

• a first circuit block, comprising:
• a first splitter configured to receive a first local oscillator signal from a first local oscillator,
• a first signal path coupled to a first output of the first splitter,
• a second signal path coupled to a second output of the first splitter,
• a first switch configured to couple the second signal path to a third signal path or to couple a fourth signal path to the third signal path, and
• a first multiplexer having a first input coupled to the first signal path and a second input coupled to the fourth signal path;
• and
• a second circuit block, comprising:
• a second splitter configured to receive a second local oscillator signal from a second local oscillator;
• a fifth signal path coupled to a first output of the second splitter;
• a sixth signal path coupled to a second output of the second splitter;
• a second switch configured to couple the sixth signal path to the third signal path or to couple a seventh signal path to the third signal path;
• and
• a second multiplexer having a first input coupled to the fifth signal path and a second input coupled to the seventh signal path;
• wherein the third signal path extends between the first circuit block and the second circuit block.
