[0030] See also Figure 1 , Figure 1 This is a flowchart of a passive device testing method in some embodiments of the present application. The present application provides a passive device testing method, which is applied to a passive device testing device for testing the transmission parameters of the passive device. The passive device testing device includes a test AC source and a test load. The test AC source is used to transmit test AC power to the test load through the passive device. Figure 1 As shown, the passive component testing methods include:

[0031] Step S100: controlling the conduction of a transmission path between a test AC source and a passive device, and controlling the disconnection of a transmission path between a test load and the passive device, to obtain a first set of test parameters of the passive device.

[0032] Step S200: controlling to disconnect the transmission path between the test AC source and the passive device, and controlling to connect the transmission path between the test load and the passive device, to obtain a second set of test parameters of the passive device.

[0033] Step S300: determining transmission parameters of the passive component based on at least the first set of test parameters and the second set of test parameters.

[0034] Among them, passive components may include electronic components such as resistors, capacitors, inductors, diodes or other integrated devices in addition to power supplies, and the connection relationship between electronic components such as resistors, capacitors, inductors, diodes or other integrated devices is unknown, and the whole device appears as a black box, that is, the electronic components and connection relationships inside the passive device are unknown, so it is difficult to test the passive device and obtain the required transmission parameters.

[0035] In some embodiments, the passive components may include one or more of a radio frequency power supply device, a radio frequency power amplifier, and an impedance matcher, and may also include other passive components.

[0036] Therefore, the above-mentioned passive device testing method in the present application can obtain the first set of test parameters and the second set of test parameters of the passive device by controlling the conduction or disconnection of the transmission path between the test AC source and the passive device, and controlling the conduction or disconnection of the transmission path between the test load and the passive device. Therefore, based on the first set of test parameters, the second set of test parameters and the load parameters, the transmission parameters of the passive device with unknown internal circuit can be quickly determined.

[0037] Please also refer to Figure 2 , Figure 2 for Figure 1 The sub-flowchart of step S300 is shown in FIG. Figure 1 、 Figure 2 As shown, step S300: determining the transmission parameters of the passive component based on at least the first set of test parameters and the second set of test parameters may specifically include:

[0038] Step S310: performing calculations based on the first set of test parameters to obtain two element values ​​of a first set of calculation results, wherein the first set of calculation results includes four element values.

[0039] Step S320: According to the second set of test parameters, obtain the other two element values ​​of the first set of operation results by calculation.

[0040] And, step S330: determining the transmission parameters of the passive device according to at least four element values ​​of the first set of operation results.

[0041] Therefore, the above-mentioned passive component testing method in the present application, when the first set of calculation results includes four element values, can calculate two of the element values ​​of the first set of calculation results according to the first set of test parameters, and can calculate the other two element values ​​of the first set of calculation results according to the second set of test parameters, and then, at least based on the four element values ​​of the first set of calculation results, can quickly determine the transmission parameters of the passive component.

[0042] Please also refer to Figure 3 , Figure 3 for Figure 2 The first set of test parameters of the passive device includes a first voltage value and a first current value at the input end of the passive device and a second voltage value at the output end of the passive device, and two element values ​​of the first set of operation results include a first element value and a second element value. Figure 2 、 Figure 3 As shown, step S310 calculates two element values ​​of the first set of calculation results based on the first set of test parameters, which may specifically include:

[0043] Step S311 : performing calculation to obtain a first element value of a first set of calculation results according to the first voltage value and the second voltage value.

[0044] Step S312 : performing calculation to obtain a second element value of the first set of calculation results according to the first current value and the second voltage value.

[0045] Therefore, the above-mentioned passive component testing method in the present application can quickly calculate the first element value and the second element value of the first operation result based on the first voltage value, the second voltage value and the first current value when the transmission path between the test AC source and the passive component is conductive and the transmission path between the test load and the passive component is disconnected.

[0046] Please also refer to Figure 4 , Figure 4 for Figure 2 The first set of test parameters of the passive device includes the third voltage value and the second current value of the input terminal of the passive device and the third current value of the output terminal of the passive device, and the other two element values ​​of the first set of operation results include the third element value and the fourth element value. Figure 2 、 Figure 4 As shown, step S320: according to the second set of test parameters, calculate and obtain the other two element values ​​of the first set of calculation results, which may specifically include:

[0047] Step S321 : performing calculation to obtain a third element value of the first set of calculation results according to the third voltage value and the third current value.

[0048] Step S322 : performing calculation to obtain a fourth element value of the first set of calculation results according to the second current value and the third current value.

[0049] Therefore, the above-mentioned passive device testing method in the present application can quickly calculate the third element value and the fourth element value of the first operation result based on the third voltage value, the second current value and the third current value when the transmission path between the test AC source and the passive device is disconnected and the transmission path between the test load and the passive device is connected.

[0050] In some embodiments, the first operation matrix can be a 2×2 matrix, the first element value of the first operation matrix can be A (located in the first row and first column, that is, the upper left corner), the third element value can be B (located in the first row and second column, that is, the upper right corner), the second element value can be C (located in the second row and first column, that is, the lower left corner), and the fourth element value can be D (located in the second row and second column, that is, the lower right corner).

[0051] Further, according to the characteristics of short circuit and / or open circuit, the first element value of the first group of operation results can be the ratio of the first voltage value to the second voltage value, the second element value of the first group of operation results can be the ratio of the first current value to the second voltage value, the third element value of the first group of operation results can be the ratio of the negative third voltage value to the third current value, and the fourth element value of the first group of operation results can be the ratio of the negative second current value to the third current value.

[0052] Please also refer to Figure 5 , Figure 5 for Figure 2 The transmission parameters of the passive device include loss parameters. Figure 2 、 Figure 5 As shown, step S330: determining the transmission parameters of the passive device based on at least four element values ​​of the first set of operation results, which may specifically include:

[0053] Step S331: determining the loss parameters of the passive component according to the four element values ​​of the first set of operation results and the load parameters of the test load.

[0054] Therefore, the above-mentioned passive component testing method in the present application, when the first set of operation results includes four element values, can quickly determine the loss parameters of the passive component based on the four element values ​​of the first set of operation results and the load parameters.

[0055] In some embodiments, the loss parameter of the passive component may include a first insertion loss and a second insertion loss.

[0056] Furthermore, the first insertion loss may be 2×(AD−BC) / X, and the second insertion loss may be 2 / X, where X=A+B / Z+C×Z+D, and Z is a load parameter.

[0057] In some embodiments, the first insertion loss may be a forward insertion loss, i.e., the insertion loss at the input end of the passive component, and the second insertion loss may be a reverse insertion loss, i.e., the insertion loss at the output end of the passive component. The forward direction may be the direction in which AC power is transmitted from the test AC source to the test load.

[0058] In some embodiments, the transmission parameters of the passive device also include reflection parameters. Figure 2 、 Figure 5 As shown, step S330: determining the transmission parameters of the passive device based on at least four element values ​​of the first set of operation results, which may specifically include:

[0059] Step S332: Determine the reflection parameters of the passive component according to the four element values ​​of the first set of operation results and the load parameters of the test load.

[0060] Therefore, the above-mentioned passive component testing method in the present application, when the first set of operation results includes four element values, can also quickly determine the reflection parameters of the passive component based on the four element values ​​of the first set of operation results and the load parameters.

[0061] In some embodiments, the reflection parameter of the passive component may include a first reflection coefficient and a second reflection coefficient.

[0062] Further, the first reflection coefficient may be (A+B / ZC×ZD) / X, and the second reflection coefficient may be (-A+B / ZC×Z+D) / X.

[0063] In some embodiments, the first reflection coefficient may be a forward reflection coefficient, i.e., a reflection coefficient at the input end of the passive component, and the second reflection coefficient may be a reverse reflection coefficient, i.e., a reflection coefficient at the output end of the passive component. The forward direction may be a transmission direction of AC power from the test AC source to the test load.

[0064] In some embodiments, the load parameter of the test load includes an impedance value.

[0065] Therefore, the above-mentioned passive component testing method in the present application can quickly calculate transmission parameters such as insertion loss and reflection coefficient simply based on the impedance value of the test load.

[0066] The passive device testing method of the present application, through the above steps, can quickly obtain the forward and reverse insertion loss and forward and reverse reflection coefficients of passive devices, even for black box passive devices, especially passive devices such as RF power supply devices, RF power amplifiers, and impedance matchers, thereby facilitating the practical application of passive devices.
