Description
Couplers are widely used in mobile communication systems, especially in indoor distribution systems. So how do you meet the need for rapid production testing? How can testing costs be reduced? This is a problem that many enterprises are facing urgently. This paper presents a set of simple and easy rapid test system, which can complete the test of all the indexes of the coupler in a short time without twisting the test port many times.

After the test is completed, the test report can be generated automatically and the data can be uploaded to MES system. The system greatly improves the testing efficiency of the production enterprise, reduces the testing cost and improves the competitiveness of the product. Coupler test index For the coupler S parameter test, mainly includes the following key parameters: frequency range: the frequency range within which the coupler can work: The fluctuation value of the interpolation loss in the frequency range, the fluctuation value of the interpolation loss = the maximum insertion loss – the minimum insertion loss: the insertion loss of the coupler, representing the coupling degree of power consumption through it: Signal power through the coupler, the difference between the power output from the coupler port and the output signal power barrier: refers to the barrier between the output port and the coupling port directionality: refers to the value of the barrier between the output port and the coupling port minus the value of the coupling degree value, directionality = barrier degree – coupling degree port return loss: This test system includes a network analyzer, a switch and a computer, which is one more computer and a switch than the conventional test. The automatic test of S parameters is realized through computer controlled network analysis and RF switch switching. After the test is completed, the software automatically produces reports and uploads data.
