Description

Technical Field

[0001] The utility model relates to the technical field of power dividers, in particular to a signal power tap with adjustable coupling degree. Background Art

[0002] In the radio frequency field, the term "Tapper" refers to a "signal power tap", also known as a signal tap, or a Tapper power divider, which is a passive radio frequency device used to extract a small part of the power from the main transmission line without causing significant power loss.

[0003] The Tapper power divider is somewhat similar to directional coupling, but the Tapper power divider is usually a three-port device, which is based on capacitive coupling rather than direct coupling and has various additional tap port structures.

[0004] The multi-port Tapper power divider can be an equal-power tap, or other types of taps that match the actual application environment. Similar to the directional coupler, in order to ensure normal operation, the tap port is usually set to have the same impedance as the main transmission line and must be properly terminated.

[0005] The directional coupler and the Tapper power divider have different coupling degrees and different internal structures. Currently on the market, the coupling degree of the Tapper is not adjustable. For example, the coupling degree of the 6DB Tapper fluctuates around the center line of 6DB for coupling fluctuations, and different coupling degree Tappers need to be purchased for engineering matching. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose a signal power tap with adjustable coupling degree.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Design a signal power tap with adjustable coupling degree, including a cavity:

[0009] Three ports are arranged on the cavity, and the three ports of the cavity are respectively connected with a connector, an inner conductor of the connector connected by a strip line, and a tetrafluoro card slot for fixing the position of the strip line;

[0010] The strip line includes a first strip line and a second strip line, and the first strip line and the second strip line are respectively connected to the guide strip;

[0011] A tetrafluoro screw rod is arranged between the first strip line and the second strip line for adjusting the gap between the first strip line and the second strip line.

[0012] Preferably, the tetrafluoro card slot is installed at the designated positions of the first strip line and the second strip line, and the installed first strip line and second strip line are inserted into the cavity.

[0013] Preferably, a 4.4 mm counterbore is made on the first strip line.

[0014] Preferably, the conductive strip is placed inside the first strip line, and the tetrafluoro screw rod is arranged on the first strip line.

[0015] Preferably, the inner conductor of the connector is screwed into the threaded holes reserved on the first strip line and the second strip line.

[0016] Preferably, the conductive strip is specifically a 50-ohm line conductive strip.

[0017] A signal power splitter with adjustable coupling degree proposed by the present utility model has the beneficial effects that: for this signal power splitter with adjustable coupling degree, when the product is already assembled, by moving the tetrafluoro screw rod to the designated coupling degree scale position, different coupling degrees at the same frequency can be achieved, which is convenient for customers to purchase. Different coupling degrees can be achieved at the same frequency, and the internal components of the product are unified, which can reduce the preparation of various internal components of the product and lower the procurement cost.
