Patent ID: 7164903

Claim:
A three-way Wilkinson power divider/combiner comprising: a first microstrip transmission line on a grounded substrate, a first end of said first microstrip transmission line provided to an input transmission line, a second end of said first microstrip transmission line provided to a first output transmission line; a second microstrip transmission line on said grounded substrate, a first end of said second microstrip transmission line provided to an input transmission line, a second end of said second microstrip transmission line provided to a second output transmission line; a third microstrip transmission line on said grounded substrate, a first end of said third microstrip transmission line provided to an input transmission line, a second end of said third microstrip transmission line provided to a third output transmission line, said second transmission line disposed between said first transmission line and said third transmission line; an insulator disposed on at least a portion of said second output transmission line; a first resistor disposed on said substrate and provided between said second end of said first microstrip transmission line and said second end of said second microstrip transmission line; a second resistor provided between said second end of said first impedance-transformer transmission line and said second end of said third impedance-transformer transmission line, said second resistor passing over at least a portion of said insulator; and a third resistor disposed on said substrate and provided between said second end of said second transmission line and said second end of said third transmission line.
