Abstract

A phase shifter assembly includes first and second phase shifters that respectively include a wiper printed circuit board and a rotatable wiper support, where the wiper printed circuit board and the wiper support are coupled in motion. The phase shifter assembly further comprises: a U-shaped bracket having first and second arms, where the first phase shifter is held on the first arm, and the second phase shifter is held on the second arm; and a rack that is linearly movably supported and is drivable to move linearly; wherein the slide holders has a tooth portion respectively, and the tooth portions are engaged with the common rack. By means of linear movement of the rack, the slide holders can be rotated respectively, and thus the slides are movable within a predetermined range respectively so as to implement phase shifts.

First claim

That which is claimed is:

1. A phase shifter assembly, comprising:
an arm and a first support leg extending at an angle from a first side of the arm;
a phase shifter including a main printed circuit board and a wiper support rotatably supported on the main printed circuit board, on the arm;
a first set of conductor guiding portions adjacent a first side of the main printed circuit board such that first conductors received by the first set of conductor guiding portions and soldered to the first side of the main printed circuit board pass into an opening in the first support leg;
a second support leg extending at an angle from a second side of the arm;
a second set of conductor guiding portions adjacent a second side of the main printed circuit board such that second conductors received by the second set of conductor guiding portions and soldered to the second side of the main printed circuit board pass into an opening in the second support leg;
wherein the first support leg includes a first lip at a distal end thereof;
wherein the second support leg includes a second lip at a distal end thereof;
wherein the first and second lips have fastening screw holes therein; and
wherein the arm, and the first and second support legs, including the first and second lips, are formed from an integral sheet of metal by punching and/or bending.

2. A phase shifter assembly, comprising:
an arm and a first support leg extending at an angle from a first side of the arm;
a phase shifter including a main printed circuit board and a wiper support rotatably supported on the main printed circuit board, on the arm;
a first set of conductor guiding portions adjacent a first side of the main printed circuit board such that first conductors received by the first set of conductor guiding portions and soldered to the first side of the main printed circuit board pass into an opening in the first support leg; and
a rack having tooth portions engaged with tooth portions of the wiper support.

3. The phase shifter assembly according to claim 2 ,
wherein the first set of conductor guiding portions are sufficiently aligned with a first side of the main printed circuit board that first conductors received by the first set of conductor guiding portions and soldered to the first side of the main printed circuit board pass through an opening in the first support leg; and
wherein the wiper support has a wiper printed circuit board fixedly mounted thereon.

4. A phase shifter assembly, comprising:
a multi-part bracket including an arm, a first support leg, having a first opening therein, extending at an angle from a first side of the arm, and a second support leg, having a second opening therein, extending at an angle from a second side of the arm;
a phase shifter including a main printed circuit board and a wiper support rotatably supported on the main printed circuit board, on the arm; and
first and second sets of conductor guiding portions extending adjacent the first and second openings in the first and second support legs, respectively;
wherein the first support leg includes a first lip at a distal end thereof; wherein the second support leg includes a second lip at a distal end thereof; and wherein the first and second lips have fastening screw holes therein; and
wherein the arm, and the first and second support legs, including the first and second lips, are formed from an integral sheet of metal by punching and/or bending.

5. A phase shifter assembly, comprising:
a multi-part bracket including an arm, a first support leg, having a first opening therein, extending at an angle from a first side of the arm, and a second support leg, having a second opening therein, extending at an angle from a second side of the arm;
a phase shifter including a main printed circuit board and a wiper support rotatably supported on the main printed circuit board, on the arm;
first and second sets of conductor guiding portions extending adjacent the first and second openings in the first and second support legs, respectively; and
a rack having tooth portions engaged with tooth portions of the wiper support.

6. The phase shifter assembly according to claim 5 , wherein the first and second sets of conductor guiding portions are aligned to the first and second openings in the first and second support legs, respectively; and wherein each of the conductor guiding portions within the first and second sets of conductive guiding portions is configured to receive a respective conductor therein.

7. A phase shifter assembly, comprising:
a multi-part bracket including a first arm and a second arm;
a first phase shifter including a first main printed circuit board and a first wiper support rotatably supported on the first main printed circuit board, on the first arm;
a second phase shifter including a second main printed circuit board and a second wiper support rotatably supported on the second main printed circuit board, on the second arm; and
a rack having tooth portions engaged with first tooth portion of the first wiper support and second tooth portion of the second wiper support;
wherein at least one of the first arm and the second arm includes a pair of support legs having lips on distal ends thereof; and
wherein the pair of support legs includes a first support leg having a first opening therein and a second support leg having a second opening therein.

8. The phase shifter assembly of claim 7 , wherein the first wiper support has a first wiper printed circuit board fixedly mounted thereon.

9. The phase shifter assembly according to claim 7 , wherein the first tooth portion extends adjacent a distal end of the first wiper support; and wherein the second tooth portion extends adjacent a distal end of the second wiper support.

10. The phase shifter assembly according to claim 7 , wherein linear movement of the rack causes rotational movement of the first wiper support and the second wiper support.

11. The phase shifter assembly according to claim 7 , further comprising a first set of conductor guiding portions extending adjacent the first opening, and a second set of conductor guiding portions extending adjacent the second opening.

12. A phase shifter assembly, comprising:
a multi-part bracket including a first arm and a second arm;
a first phase shifter including a first main printed circuit board and a first wiper support rotatably supported on the first main printed circuit board, on the first arm;
a second phase shifter including a second main printed circuit board and a second wiper support rotatably supported on the second main printed circuit board, on the second arm; and
a rack having tooth portions engaged with first tooth portion of the first wiper support and second tooth portion of the second wiper support;
wherein the first arm is stacked vertically relative to the second arm; and
