Abstract

A power divider and an electronic device are provided. The power divider includes: a main port having an input characteristic admittance; a first output port having a first characteristic admittance; a second output port having a second characteristic admittance, where the second and the first characteristic admittances have a predetermined ratio relationship; a first adjustment branch coupled between the main port and the first output port; and a second adjustment branch coupled between the main port and the second output port. The input characteristic admittance is a sum of admittances presented by the first and second adjustment branches at the main port. The admittance presented by the first adjustment branch at the main port and the admittance presented by the second adjustment branch at the main port are adjustable and the input characteristic admittance is enabled to be equal to a sum of the first and the second characteristic admittances.

First claim

What is claimed is:

1. A power divider, comprising:
a main port having an input characteristic admittance;
a first output port having a first characteristic admittance;
a second output port having a second characteristic admittance, wherein the second characteristic admittance and the first characteristic admittance have a predetermined ratio relationship;
a first adjustment branch, coupled between the main port and the first output port; and
a second adjustment branch, coupled between the main port and the second output port, wherein the input characteristic admittance is a sum of an admittance presented by the first adjustment branch at the main port and an admittance presented by the second adjustment branch at the main port, wherein the admittance presented by the first adjustment branch at the main port and the admittance presented by the second adjustment branch at the main port are adjustable, and wherein the input characteristic admittance is enabled to be equal to a sum of the first characteristic admittance and the second characteristic admittance;
wherein the first adjustment branch comprises a first odd-even mode circuit and a first adjustable reactor, and the first odd-even mode circuit has a first odd-mode admittance and a first even-mode admittance; and
the second adjustment branch comprises a second odd-even mode circuit and a second adjustable reactor, and the second odd-even mode circuit has a second odd-mode admittance and a second even-mode admittance.

2. The power divider according to claim 1 , wherein:
an admittance of the first adjustable reactor and an admittance of the second adjustable reactor are adjustable, and a difference between the admittance of the first adjustable reactor and the admittance of the second adjustable reactor is a fixed value.

3. The power divider according to claim 2 , wherein the first odd-even mode circuit and the first adjustable reactor are coupled in parallel between the main port and the first output port, and
wherein the second odd-even mode circuit and the second adjustable reactor are coupled in parallel between the main port and the second output port.

4. The power divider according to claim 2 , wherein admittances of the first odd-even mode circuit, the second odd-even mode circuit, the first adjustable reactor, and the second adjustable reactor satisfy the following relationship:
