[0032] See also Figure 1 , Figure 1 This is a flow chart of an operating condition testing method in an embodiment of the present application. The present application provides an operating condition testing method, which is used to test and obtain the operating conditions of a DC power supply unit and a radio frequency power amplifier, wherein the operating conditions include at least a first stable operating condition and an unstable operating condition, and is characterized in that the radio frequency power amplifier is used to input a crystal oscillator signal and a DC voltage output by the DC power supply unit, and amplify the power of the crystal oscillator signal according to the voltage value of the DC voltage to obtain a radio frequency signal with a target power value. Figure 1 As shown, the operating condition test method includes:

[0033] Step S100: controlling the DC power supply unit and the RF power amplifier to operate together under a plurality of different operating conditions.

[0034] Step S200: Obtain a first set of test parameters between the DC power supply unit and the RF power amplifier under each operating condition, and obtain a second set of test parameters between the RF power amplifier and the test resistor under each operating condition, thereby obtaining multiple first sets of test parameters and multiple second sets of test parameters corresponding to multiple different operating conditions.

[0035] Step S300: Determine the operating efficiency of the RF power amplifier under each operating condition according to the first set of test parameters and the second set of test parameters obtained under each operating condition, thereby obtaining a plurality of operating efficiencies corresponding to a plurality of different operating conditions.

[0036] Step S400: determining each operating condition as a first stable operating condition or an unstable operating condition at least according to a magnitude relationship between the operating efficiency of each operating condition and a first preset efficiency.

[0037] Therefore, the above-mentioned operating condition testing method in the present application, by controlling the DC power supply unit and the RF power amplifier to operate together under multiple different operating conditions, and respectively obtaining multiple first groups of test parameters and multiple second groups of test parameters corresponding to the multiple different operating conditions, can obtain multiple operating efficiencies corresponding to the multiple different operating conditions, so as to quickly test the DC power supply unit and the RF power amplifier to determine that each operating condition is a first stable operating condition or an unstable operating condition, at least based on the relationship between the operating efficiency of each operating condition and the first preset efficiency, so as to protect the RF power amplifier.

[0038] The operating efficiency of each operating condition refers to the operating efficiency corresponding to each operating condition. After obtaining a plurality of operating efficiencies corresponding to a plurality of different operating conditions respectively according to step S300, the operating efficiency corresponding to each operating condition can be known.

[0039] In one or more embodiments, a first set of test parameters between the DC power supply unit and the RF power amplifier is obtained under each operating condition, which may be a first set of test parameters at the input end of the RF power amplifier under each operating condition, a second set of test parameters between the RF power amplifier and the test resistor is obtained under each operating condition, which may be a second set of test parameters at the output end of the RF power amplifier under each operating condition.

[0040] In one or more embodiments, a crystal oscillator signal may be output to a radio frequency power amplifier via a quartz crystal oscillator unit.

[0041] In one or more embodiments, the test resistor may be a load.

[0042] Please also read Figure 2 , Figure 2 for Figure 1A sub-flow chart of step S100 in FIG. Figure 1 , Figure 2 As shown, step S100: controlling the DC power supply unit and the RF power amplifier to operate together under a plurality of different operating conditions may specifically include:

[0043] Step S110: Output multiple first control signals with different conduction duty cycles to the DC power supply unit respectively, and continuously output a second control signal with a certain duty cycle to the RF power amplifier to control the DC power supply unit and the RF power amplifier to operate together under multiple different operating conditions.

[0044] When the on-duty cycle of the first control signal is different, the DC power supply unit and the RF power amplifier operate together under different operating conditions.

[0045] The on-duty ratio of the second control signal may be 50%.

[0046] Among them, both the DC power supply unit and the RF power amplifier may include switches, and the conduction duty cycle of the switch of the DC power supply unit and the switch of the RF power amplifier are controlled correspondingly by the first control signal and the second control signal, so as to control the DC power supply unit and the RF power amplifier to operate together under multiple different operating conditions.

[0047] In particular, the DC voltage output by the DC power supply unit can be used to change according to the change of the on-duty ratio of the first control signal.

[0048] Therefore, the above-mentioned operating condition testing method in the present application realizes controlling the DC power supply unit and the RF power amplifier to operate together under multiple different operating conditions by outputting multiple first control signals with different conduction duty cycles to the DC power supply unit respectively, and continuously outputting a second control signal with a certain duty cycle to the RF power amplifier, thereby determining the operating conditions for the joint operation of the DC power supply unit and the RF power amplifier based on the conduction duty cycle of the first control signal.

[0049] Please also read Figure 3 , Figure 3 for Figure 1 A sub-flow chart of step S300 in FIG. Figure 1 , Figure 3 As shown, step S300: determining the operating efficiency of the RF power amplifier corresponding to each operating condition according to the first set of test parameters and the second set of test parameters obtained under each operating condition, thereby obtaining multiple operating efficiencies corresponding to multiple different operating conditions, which may specifically include:

[0050] Step S310: Determine the input power value corresponding to the RF power amplifier under each operating condition according to the first set of test parameters obtained under each operating condition.

[0051] Step S320: determining the output power value corresponding to the RF power amplifier under each operating condition according to the second set of test parameters obtained under each operating condition.

[0052] And, step S330: determining the operating efficiency of the RF power amplifier under each operating condition according to the output power value and the input power value corresponding to each operating condition, thereby obtaining multiple operating efficiencies corresponding to multiple different operating conditions.

[0053] Therefore, the above-mentioned operating condition testing method in the present application determines the operating efficiency of the RF power amplifier by determining the input power value and output power value of the RF power amplifier, and can quickly obtain multiple operating efficiencies corresponding to multiple different operating conditions.

[0054] Please also read Figure 4 , Figure 4 for Figure 3 A sub-flow chart of step S310 and step S320 in FIG. The first set of test parameters includes a first voltage value, a first current value, and a first power factor, and the second set of test parameters includes a second voltage value, a second current value, and a second power factor. Figure 3 , Figure 4 As shown, step S310: determining the input power value corresponding to each operating condition of the RF power amplifier according to the first set of test parameters obtained under each operating condition, which may specifically include:

[0055] Step S311: Determine the input power value corresponding to the RF power amplifier under each operating condition according to the product of the first voltage value, the first current value and the first power factor of the first set of test parameters obtained under each operating condition.

[0056] The first voltage value and the first current value may both be effective values, and the first power factor may be a cosine value.

[0057] Step S320: determining the output power value of the RF power amplifier corresponding to each operating condition according to the second set of test parameters obtained under each operating condition, which may specifically include:

[0058] Step S321: Determine the output power value corresponding to the RF power amplifier under each operating condition according to the product of the second voltage value, the second current value and the second power factor of the first set of test parameters obtained under each operating condition.

[0059] The second voltage value and the second current value may both be effective values, and the second power factor may be a cosine value.

[0060] Therefore, the above-mentioned operating condition testing method in the present application can avoid the AC component interference existing at the input and output ends of the RF power amplifier by obtaining the first power factor and the second power factor, thereby obtaining more accurate input power value and output power value.

[0061] In one or more embodiments, since the input end of the RF power amplifier is used to input a DC voltage, it indicates that the first power factor of the phase angle between the voltage and the current is 1 or close to 1, which will not affect the calculation. In order to save steps, step S310: determine the input power value corresponding to the RF power amplifier under each operating condition according to the first set of test parameters obtained under each operating condition. Specifically, it may also include: determining the input power value corresponding to the RF power amplifier under each operating condition according to the product of the first voltage value and the first current value of the first set of test parameters obtained under each operating condition.

[0062] Please also read Figure 5 , Figure 5 for Figure 3 A sub-flow chart of step S330 in FIG. Figure 3 , Figure 5 As shown, step S330: according to the output power value and the input power value corresponding to each operating condition, determine the operating efficiency of the RF power amplifier under each operating condition, so as to obtain multiple operating efficiencies corresponding to multiple different operating conditions, which may specifically include:

[0063] Step S331: Determine the operating efficiency of the RF power amplifier under each operating condition according to the quotient of the output power value and the input power value under each operating condition, thereby obtaining a plurality of operating efficiencies corresponding to a plurality of different operating conditions.

[0064] Therefore, the above-mentioned operating condition testing method in the present application obtains the ratio of the output power value to the input power value as the operating efficiency of the RF power amplifier, so as to judge the power loss of the RF power amplifier and determine whether the RF power amplifier needs to be protected.

[0065] Please also read Figure 6 , Figure 6 for Figure 1 A sub-flow chart of step S400 in FIG. Figure 1 , Figure 6 As shown, step S400: determining each operating condition as a first stable operating condition or an unstable operating condition at least according to the magnitude relationship between the operating efficiency of each operating condition and the first preset efficiency, may specifically include:

[0066] Step S410: if the operating efficiency of a certain operating condition is greater than a first preset efficiency, the certain operating condition is determined to be a first stable operating condition; if the operating efficiency of a certain operating condition is less than the first preset efficiency, the certain operating condition is determined to be an unstable operating condition.

[0067] Therefore, the above operating condition test method in the present application indicates that when the operating efficiency of a certain operating condition is greater than the first preset efficiency, the operating efficiency is high, and the certain operating condition is determined to be the first stable operating condition; when the operating efficiency of a certain operating condition is less than the first preset efficiency, the operating efficiency is too low, and the certain operating condition is determined to be an unstable operating condition. Thus, the operating state of the RF power amplifier can be reflected according to the operating efficiency, and then the operating state of the RF power amplifier can be obtained by comparing the magnitude relationship between the operating efficiency and the first preset efficiency.

[0068] Please also read Figure 7 , Figure 7 for Figure 1 Another sub-flow chart of step S400 in FIG. The operating condition also includes a second stable operating condition. Figure 1 , Figure 7 As shown, step S400: determining each operating condition as a first stable operating condition or an unstable operating condition at least according to the magnitude relationship between the operating efficiency of each operating condition and the first preset efficiency, may specifically include:

[0069] Step S420: Determine each operating condition as one of the second stable operating condition, the first stable operating condition and the unstable operating condition based on the relationship between the operating efficiency of each operating condition and the first preset efficiency and the relationship between the operating efficiency of each operating condition and the second preset efficiency.

[0070] The second preset efficiency is greater than the first preset efficiency.

[0071] Therefore, the above-mentioned operating condition testing method in the present application, by setting the second stable operating condition, can determine whether each operating condition is the second stable operating condition when the operating efficiency of the RF power amplifier is greater than the first preset efficiency value, according to the relationship between the operating efficiency of each operating condition and the second preset efficiency.

[0072] Please also read Figure 8 , Figure 8 for Figure 7 A sub-flow chart of step S420 in FIG. Figure 1 , Figure 8As shown, step S420: determining each operating condition as one of the second stable operating condition, the first stable operating condition, and the unstable operating condition according to the magnitude relationship between the operating efficiency of each operating condition and the first preset efficiency and the magnitude relationship between the operating efficiency of each operating condition and the second preset efficiency, may specifically include:

[0073] Step S421: If the operating efficiency of a certain operating condition is greater than the second preset efficiency, the operating condition is determined to be the second stable operating condition; if the operating efficiency of a certain operating condition is less than the second preset efficiency and greater than the first preset efficiency, the operating condition is determined to be the first stable operating condition; if the operating efficiency of a certain operating condition is less than the first preset efficiency, the operating condition is determined to be the unstable operating condition.

[0074] Therefore, the above-mentioned operating condition testing method in the present application further compares the operating efficiency of a certain operating condition with the second preset efficiency, and can further determine that a certain operating condition is the second stable operating condition or the first stable operating condition.

[0075] In one or more embodiments, the target power value of the RF signal output by the RF power amplifier under the second stable operating condition, the first stable operating condition, and the unstable operating condition decreases in sequence.

[0076] Furthermore, the target power value of the RF signal output by the RF power amplifier under unstable operating conditions may be zero.

[0077] It should be noted that since the RF power amplifier does not contain energy-consuming devices, the greater the difference between the output power value and the input power value of the RF power amplifier during operation, the more unstable the operating state of the RF power amplifier is, and it is easy to be damaged. Therefore, when the difference between the output power value and the input power value is too large, lowering the target power value of the RF signal output by the RF power amplifier in the operating state, or directly stopping the operation of the RF power amplifier, can effectively protect the RF power amplifier.

[0078] The operating condition testing method of the present application, through the above steps, obtains the operating conditions of the DC power supply unit and the RF power amplifier through testing, and can accurately and effectively protect the RF power amplifier, preventing the RF power amplifier from being destroyed by reflected power, thereby maintaining the output stability of the RF power amplifier.
