Patent ID: 7184735

Claim:
A radio frequency (RF) circuit comprises: a first differential RF path having at least one RF block, wherein the at least one RF block of the first differential RF path includes a first differential section and a second differential section, wherein the first differential section of the at least one RF block of the first differential RF path is symmetrical with the second differential section of the at least one RF block of the first differential RF path; and a second differential RF path having at least one RF block, wherein the at least one RF block of the second differential RF path includes a first differential section and a second differential section, wherein the first differential section of the at least one RF block of the second differential RF path is symmetrical with the second differential section of the at least one RF block of the second differential RF path, wherein the first and second half differential sections of the at least one RF block of the first differential RF path are symmetrically placed on at least one layer around the first and second half differential sections of the at least one RF block of the second differential RF path, wherein the first and second half differential sections of the at least one RF block of the second differential RF path are fabricated on the at least one layer.
