Abstract:
1. An integrated circuit comprising: an input terminal; a first circuit portion comprising a first coupler coupled to the input terminal, and a first mixer coupled to the first coupler; a first antenna terminal coupled to the first coupler; a second circuit portion comprising a second coupler coupled to the input terminal, and a second mixer coupled to the second coupler; a second antenna terminal coupled to the second coupler; wherein the input terminal is a differential input terminal; and wherein the first coupler is coupled to a first terminal pole of the differential input terminal via a first line, and the second coupler is coupled to a second terminal pole of the differential input terminal via a second line; or wherein the first coupler and the second coupler are coupled to the differential input terminal via differential lines and a differential power divider.
