Abstract

The present disclosure relates to a linkage mechanism for a phase shifter assembly, comprising a rotation device having a rotation shaft fixed to a substrate of the phase shifter assembly and a rotation member configured to rotate about said rotation shaft; a first drive member which can be operatively engaged to the rotation member such that rotation of the rotation member can cause movement of the first drive member; a second drive member disposed on and moving together with the rotation member; and a translation device including a translation member which can be operatively engaged to the second drive member such that movement of the second drive member can cause movement of the translation member, wherein the rotation device and the translation device are configured to move in association with each other during operation of the phase shifter assembly. The present disclosure also relates to a phase shifter assembly including the above-mentioned linkage mechanism.

First claim

The invention claimed is:

1. A linkage mechanism for a phase shifter assembly, comprising:
a rotation device including:
a rotation shaft fixed to a secured substrate of the phase shifter assembly; and
a rotation member pivotally coupled to the rotation shaft and configured to rotate about the rotation shaft in a plane substantially parallel to the substrate;

a first drive member that is operatively engaged to the rotation member such that rotation of the rotation member causes movement of the first drive member;
a second drive member disposed on and moving together with the rotation member; and
a translation device including:
a translation member that is operatively engaged to the second drive member such that movement of the second drive member causes movement of the translation member,

wherein the rotation device and the translation device are configured to move in association with each other during operation of the phase shifter assembly.

2. The linkage mechanism according to claim 1 , wherein movement of the translation device with respect to the first drive member can be adjusted by adjusting a location of the first drive member and/or the second drive member with respect to the rotation shaft.

3. The linkage mechanism according to claim 1 , wherein the rotation member is provided with a guide, along which the first drive member can move.

4. The linkage mechanism according to claim 1 , wherein the translation member is provided with a guide, along which the second drive member can move.

5. The linkage mechanism according to claim 1 , wherein the first drive member is configured to be operatively engaged to the rotation member at different positions along the rotation member so as to change the proportional relationship between movement of the rotation member and movement of the first drive member.

6. The linkage mechanism according to claim 1 , wherein the second drive member is configured to be fixed to the rotation member at different positions along the rotation member so as to change the proportional relationship between movement of the rotation member and movement of the translation member.

7. The linkage mechanism according to claim 1 , wherein the linkage mechanism is further provided with a third drive member disposed on the rotation member and coupled to an external drive source, wherein the third drive member is configured to drive the rotation member to rotate about the rotation shaft.

8. The linkage mechanism according to claim 1 , wherein the translation device further includes a connection member, the translation member being fixed to the connection member.

9. A phase shifter assembly, comprising:
the linkage mechanism according to claim 1 ;
a first-stage phase shifter, the first drive member being coupled to the first-stage phase shifter; and
a second-stage phase shifter, the translation member being coupled to the second-stage phase shifter.

10. The phase shifter assembly according to claim 9 , wherein a portion of the first-stage phase shifter and a portion of the second-stage phase shifter are disposed on the same printed circuit board and operate in association with each other by means of the linkage mechanism.

11. The phase shifter assembly according to claim 9 , wherein an output ratio between the first-stage phase shifter and the second-stage phase shifter can be adjusted by adjusting a location of the first drive member and/or a location of the second drive member with respect to the rotation shaft.

12. The phase shifter assembly according to claim 9 , wherein the first-stage phase shifter is a rotary phase shifter and the second-stage phase shifter is a sliding phase shifter.

13. The phase shifter assembly according to claim 9 , wherein the phase shifter assembly includes one first-stage phase shifter and a plurality of second-stage phase shifters.

14. The phase shifter assembly according to claim 9 , wherein the phase shifter assembly includes one first-stage phase shifter and five second-stage phase shifters.

15. The phase shifter assembly according to claim 9 , wherein the translation device further includes a connection member, the translation member being fixed to the connection member.

16. The phase shifter assembly according to claim 15 , wherein the connection member includes connection rods arranged in parallel to each other and a cross member arranged substantially perpendicular to the connection rods and connecting the connection rods to each other.

17. The phase shifter assembly according to claim 16 , wherein the phase shifter assembly further includes a fourth drive member fixed to the second-stage phase shifter, wherein the cross member is operatively coupled to the fourth drive member so that the translation member drives the second-stage phase shifter to operate via the connection member, the cross member and the fourth drive member.

18. The phase shifter assembly according to claim 17 , wherein the cross member is provided with a guide, and the fourth drive member can move along the guide of the cross member.

19. A phase shifter assembly, comprising:
a printed circuit board;
a first electromechanical phase shifter that is partially implemented on the printed circuit board, the first electromechanical phase shifter including a first moveable member;
a second electromechanical phase shifter that is partially implemented on the printed circuit board, the second electromechanical phase shifter including a second moveable member; and
a mechanical linkage mechanism that moves the second moveable member in response to movement of the first moveable member,
wherein the first electromechanical phase shifter is a rotary phase shifter and the second electromechanical phase shifter is a linearly sliding phase shifter.
