Abstract
A passive component comprising a first port and a second port, wherein the first and second ports are provided on a first axis, a third port and a fourth port, wherein the third and fourth ports are provided on a second axis perpendicular to the first axis, and a transmission line arrangement comprising four transmission lines, wherein the first port and the second port are each coupled to both the third port and the fourth port by respective transmission lines of the transmission line arrangement, wherein each transmission line follows a meandering path and each transmission line has the same length, such that the transmission line arrangement is symmetrical about at least one axis of symmetry.

A passive component comprising:
- a first port and a second port, wherein the first and second ports are provided on a first axis;
- a third port and a fourth port, wherein the third and fourth ports are provided on a second axis perpendicular to the first axis;
- and
- a transmission line arrangement comprising four transmission lines, wherein the first port and the second port are each coupled to both the third port and the fourth port by respective transmission lines of the transmission line arrangement, wherein each transmission line follows a meandering path and each transmission line has a substantially equal physical path length, such that the transmission line arrangement is symmetrical about at least one axis of symmetry.
An amplifier comprising:
- a passive component with
- a first port and a second port, wherein the first and second ports are provided on a first axis,
- a third port and a fourth port, wherein the third and fourth ports are provided on a second axis perpendicular to the first axis, and
- a transmission line arrangement comprising four transmission lines that form a bypass path, wherein the first port and the second port are each coupled to both the third port and the fourth port by respective transmission lines of the transmission line arrangement, wherein each transmission line follows a meandering path and each transmission line has a substantially equal physical path length, such that the transmission line arrangement is symmetrical about at least one axis of symmetry;
- a ground shield provided as a bottom layer;
- and
- at least one active component below the ground shield.
A method of manufacturing a passive component, comprising:
- providing a substrate;
- forming a first port and a second port on the substrate, wherein the first and second ports are provided on a first axis;
- forming a third port and a fourth port on the substrate, wherein the third and fourth ports are provided on a second axis perpendicular to the first axis;
- and
- forming a transmission line arrangement on the substrate, the transmission line arrangement comprising four transmission lines, wherein the first port and the second port are each coupled to both the third port and the fourth port by respective transmission lines of the transmission line arrangement, and wherein each transmission line follows a meandering path and each transmission line has a substantially equal physical path length, such that the transmission line arrangement is symmetrical about at least one axis of symmetry.
