Abstract
Systems and methods for ferrite circulator phase shifters are provided. In one embodiment, a multi-bit phase shifter comprises: a first switching circulator having a first port coupled to a first short circuit of a first phase length; and a second switching circulator coupled in series with the first switching circulator, the second switching circulator having a second port coupled to a second short circuit of a second phase length, the second switching circulator configured to switch in the second short circuit when the first short circuit is switched out by the first switching circulator, and switch out the second short circuit when the first short circuit is switched in by the first switching circulator.
Claims14
A multi-bit phase shifter comprising:
- a first switching circulator having a first port coupled to a first short circuit of a first phase length;
- and
- a second switching circulator coupled in series with the first switching circulator, the second switching circulator having a second port coupled to a second short circuit of a second phase length;
- a bit driver coupled to the first switching circulator and the second switching circulator, wherein the bit driver switches the first switching circulator and the second switching circulator as a pair such that the second short circuit is switched in when the first short circuit is switched out, and the first short circuit is switched out when the second short circuit is switched in.
A system comprising at least one multi-bit phase shifter, the at least one multi-bit phase shifter comprising:
- a plurality of switch circulator pairs coupled in series to define an RF energy waveguide path, each of the plurality of switch circulator pairs defining a bit of the multi-bit phase shifter;
- wherein a first switch circulator pair of the plurality of switch circulator pairs comprises:
- a first switching circulator having a first port coupled to a first short circuit of a first phase length;
- and
- a second switching circulator coupled in series with the first switching circulator, the second switching circulator having a second port coupled to a second short circuit of a second phase length;
- a bit driver coupled to the first switching circulator and the second switching circulator, wherein the bit driver switches the first switching circulator and the second switching circulator as a pair such that the second short circuit is switched in when the first short circuit is switched out, and the first short circuit is switched out when the second short circuit is switched in.
