Description

Technical Field

[0001] The present application relates to the field of radio frequency circuit technology, and in particular to a temperature compensation method, system and computer-readable storage medium. Background Art

[0002] Receivers and transmitters are two carrier forms of RF circuits. Receivers are mainly used to filter, mix, demodulate, and decode received RF signals to restore the target signal. Transmitters are mainly used to modulate, transform, and power the RF signals to be transmitted, and finally transmit them through antennas. In RF circuits, the transmission power and receiving gain of each component inside are affected by the ambient temperature. Specifically, in high temperature environments, the link gain of the receiver decreases and the noise factor increases; in low temperature environments, the link gain of the receiver increases and the noise factor decreases. For example, high and low temperature environments will directly lead to a decrease in the performance of the PA (Power Amplifier) ​​of the receiver, resulting in differences in high and low temperature output power, which ultimately leads to different results for the link gain of the receiver at different ambient temperatures.

[0003] At present, most of the temperature compensation in related technologies is to control the ambient temperature of the RF circuit through an external temperature box to keep the ambient temperature at the target temperature, and then achieve power compensation by modifying the non-volatile memory.

It should also be understood that, unless clearly stated in this application, words defined in common dictionaries should be interpreted as having the same meaning as their meaning in the context of the relevant technology, and should not be interpreted in an idealized or overly formal sense.

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. In addition, unless explicitly limited or contradictory to the context, the specific steps included in the method described in the present application are not necessarily limited to the order described, but can be performed in any order or in parallel. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0030] The background of this application is that the RF power of each component in the RF circuit will be affected by the ambient temperature, and the receiver or transmitter with built-in RF circuit usually works in a wide temperature environment, such as -40 degrees Celsius to 75 degrees Celsius, which causes the RF power of the RF circuit to be unable to maintain a stable state at different temperatures. Based on this, temperature compensation is required, that is, obtaining the corresponding power offset at different external temperature values, and then using the corresponding power offset at each external temperature value to compensate the RF power of the RF circuit, so that the RF circuit can have the same RF power at various external temperature values.

[0031] Figure 1 is a flow chart of a method for temperature compensation according to one aspect of the present application.

[0032] like Figure 1 As shown, the present application provides such a temperature compensation method, which may include:

[0033] Step S110, collecting multiple internal temperature values ​​of the measured element when processing an input signal, and actual radio frequency power of the measured element corresponding to each internal temperature value;

[0034] Step S120, calculating the power offset of the measured element when it is at each internal temperature value according to each internal temperature value and its corresponding actual RF power;

[0035] Step S130: Compensating the actual RF power using the power offset so that the component under test maintains outputting the target RF power at each internal temperature value.

[0036] In some embodiments, the main device for implementing the present application may include: a power compensation tool built into the computer, a comprehensive tester, and a component under test. The power compensation tool built into the computer is mainly used to provide an input signal to the component under test through the comprehensive tester, and to calculate the power offset that needs to be compensated for different internal temperature values ​​according to the corresponding RF power of the component under test at different internal temperature values, so that the component under test outputs the target RF power at each internal temperature value; a calibration file can also be created and a temperature compensation value can be obtained. The component under test is a radio frequency system that can transmit and receive, including PA and LNA (Low Noise Amplifier). Of course, it can also be other components, but PA and LNA are more sensitive to temperature changes, so this application uses these two components as the components under test for description. Among them, PA is an amplifier that can generate maximum power output to drive a certain load (such as a speaker); LNA is an amplifier with a very low noise coefficient, generally used as a high-frequency or intermediate-frequency preamplifier of various radio receivers (such as WiFi in mobile phones, computers or iPADs), and an amplification circuit of a highly sensitive electronic detection device. The integrated tester is used to debug the test conditions according to the power compensation tool built into the computer, and then provide the input signal of the power compensation tool to the component under test.

[0037] In some embodiments, a power compensation tool built into the computer generates an input signal according to the test requirements, and provides the input signal to the component under test through the integrated tester; the component under test processes the input signal, and the component under test will inevitably generate a certain amount of heat during the processing; then the power compensation tool will provide the input signal to the component under test at a preset number of times to ensure that the component under test can reach a sufficiently high internal temperature value by continuously processing the input signal; finally, when the internal temperature value of the component under test reaches the target temperature value, the input signal is stopped from being provided to the component under test. Obviously, the above process does not require the intervention of an external temperature box or other heating elements, and avoids the labor cost of multiple adjustments to the temperature value of the external temperature box. For example, the internal temperature value of the environment in which the current measured element is located is 25 degrees Celsius. When the power compensation tool provides an input signal to the measured element, the input signal can be a 24 decibel milliwatt (dBm) tone. The measured element will amplify the tone, and the temperature of the measured element will slowly rise. If the measured element does not directly reach the target temperature value by processing a tone with 24dBm once, the number of test iterations can be set so that the measured element generates enough heat to raise the temperature of the measured element to the target temperature value after continuously processing multiple tones with 24dBm. It is known to those skilled in the art that the number of iterations can be set according to actual conditions, and this application does not limit this.

[0038] In some embodiments, since the RF power generated by the DUT is affected by temperature, different RF powers are generated in different stages of processing the input signal, that is, in environments with different internal temperature values. Furthermore, at each stage when the DUT generates heat due to processing the input signal, the actual RF power of the DUT at each internal temperature value is collected.

[0039] In some embodiments, after collecting the internal temperature values ​​within a certain temperature range and the actual RF power of the measured element corresponding to them, a temperature compensation curve is constructed to characterize the corresponding relationship between each internal temperature value and the actual RF power of the measured element. It should be noted that since the relationship between the internal temperature values ​​within a certain temperature range and the actual RF power of the measured element corresponding to them is not a linear relationship, it is impossible to simply use a smooth curve or a straight line to define the relationship between the two. However, it can be imagined that when the numerical values ​​of the two internal temperature values ​​are infinitely close, the magnitude of the actual RF power of the measured element corresponding to them will also be infinitely close. Therefore, in the temperature interval formed by two adjacent internal temperature values, the relationship between the internal temperature value and the actual RF power of the measured element can be approximated as a linear relationship. In the present application, 1 degree Celsius is used as the temperature difference accuracy between adjacent internal temperature values ​​for collecting internal temperature values. Of course, a higher temperature difference accuracy can be set according to demand for collecting internal temperature values, which is not limited here.

[0040] Furthermore, a rectangular coordinate system is constructed with RF power (in decibel milliwatts dBm) as the vertical axis and internal temperature value (in degrees Celsius °C) as the horizontal axis, and multiple temperature compensation points consisting of each internal temperature value and its corresponding actual RF power of the measured element are determined in the rectangular coordinate system. Since the relationship between the internal temperature value and the actual RF power of the measured element in the same temperature interval can be approximately expressed as a linear relationship, in order to accurately describe the temperature compensation curve within a certain temperature range, the temperature range between two internal temperature values ​​with adjacent numerical values ​​can be taken as a temperature interval, and the curves of each temperature interval are drawn separately. Based on the above, when the temperature difference accuracy meets the requirements, the relationship between the internal temperature value and the actual RF power of the measured element in the same temperature interval can be approximately expressed as a linear relationship, that is, the temperature compensation points corresponding to the two end points of each temperature value interval can be connected, and the line segment corresponding to the connection line can represent the corresponding relationship between each internal temperature value in the corresponding temperature interval and the actual RF power of the measured element, and the slope of the line segment is the temperature compensation slope of the temperature interval. Finally, the set of line segments in each temperature interval that characterize the correspondence between the internal temperature value and the actual RF power of the corresponding measured element is the temperature compensation curve of the temperature range. It should be noted that the temperature compensation slope can be positive or negative.

[0041] In some embodiments, according to different power amplification requirements for the input signal, the RF power output by the measured element can be high power output or low power output. Of course, the measured element can also generate receiving gain in a closed-loop scenario. Therefore, in different demand scenarios, even in the same temperature range, the RF power values ​​of the measured element corresponding to each internal temperature value are different. In addition, since different regions use different frequency bands, for example, some regions use low frequency and some regions use medium frequency, there are different RF paths inside the measured element. Different RF paths can correspond to different temperature compensations. Even in the same RF power scenario and the same internal temperature value, the actual RF power values ​​of the measured element corresponding to each internal temperature value will result in different results.

[0042] Figure 2 This is a schematic diagram of the corresponding relationship between RF power and temperature in a high-power scenario; Figure 3 is a schematic diagram of the corresponding relationship between RF power and temperature in a low-power scenario; and Figure 4 This is a schematic diagram of the corresponding relationship between RF power and temperature in a closed-loop scenario.

[0043] like Figure 2 As shown in the figure, it is the corresponding relationship between RF power and temperature in a high-power scenario. The detected temperature range is 31°C to 50°C. Corresponding to each internal temperature value within this temperature range, the actual RF power of the measured component fluctuates between 22.34dBm and 22.77dBm. For example, when the internal temperature value is 31°C, the actual RF power of the measured component is 22.77dBm. When the internal temperature value is 48°C, 49°C or 50°C, the actual RF power of the measured component is 22.34dBm, etc., which are not listed here one by one. Figure 3 As shown in the figure, it is the corresponding relationship between RF power and temperature in low-power scenarios. The detected temperature range is 32℃ to 34℃. Corresponding to each internal temperature value within this temperature range, the actual RF power of the measured component fluctuates between -1.59dBm and -1.55dBm. For example, when the internal temperature value is 32℃, the actual RF power of the measured component is -1.55dBm, and when the internal temperature value is 33℃, the actual RF power of the measured component is -1.59dBm, etc., which are not listed here one by one. Figure 4 The figure shows the corresponding relationship between RF power and temperature in a closed-loop scenario. The detected temperature range is 31°C to 50°C. Corresponding to the internal temperature values ​​within this temperature range, the actual RF power of the measured component fluctuates between -19.14dBm and -18.82dBm. For example, when the internal temperature value is 43°C, the actual RF power of the measured component is -19.01dBm, and when the internal temperature value is 49°C, the actual RF power of the measured component is -19.14dBm, etc., which are not listed here one by one.

[0044] It should be noted that this application only lists the corresponding relationship between each internal temperature value and the actual RF power in high-power scenarios, low-power scenarios and closed-loop scenarios, to show that even the actual RF power corresponding to the same internal temperature value in different power scenarios has different values. Therefore, not all the intermediate frequency signal channels and low-frequency signal channels corresponding to different scenarios are listed and processed. However, in the actual test process, the temperature compensation slope of each temperature range will produce six different values ​​for different power scenarios and different signal channels. Subsequently, the six different temperature compensation slopes need to be processed separately according to different power scenarios and different signal channels, and then the power offset corresponding to different power scenarios and different signal channels at the same internal temperature value can be obtained to compensate the actual RF power according to the actual situation.

[0045] In some embodiments, the temperature compensation slopes of each temperature interval in the temperature compensation curve are respectively input into a computer-side power compensation tool, and the power compensation tool calculates the power offset corresponding to each internal temperature value based on the temperature compensation slopes of each internal temperature value and the temperature interval in which it is located, wherein the power compensation tool uses a power offset formula when calculating the power offset.

[0046] In some implementations, the power offset formula may be expressed as:

[0047]

[0048] In formula (1), M is the temperature compensation slope, T 1 is the normal temperature value, T 2 is the internal temperature value, D is the measured element at T 2 The power offset at .

[0049] For example, let the normal temperature value T 1 is 25℃, if the current internal temperature value T 2 If the temperature is 55℃, obtain T 2 The corresponding temperature compensation value M is -43, and then the measured component can be calculated by formula (1) at T 2 The power offset D is +1.26 dB. Of course, this example is the result in a high power scenario.

[0050] In some embodiments, the actual RF power is compensated by the power offset so that the measured element outputs the target RF power at each internal temperature value. For example, if the current actual RF power is 23dBm and the power offset is +1.26dB, the actual RF power is compensated by the power offset to obtain a target RF power of 24.26dBm.

[0051] In some embodiments, due to individual differences in the internal components of the measured element, multiple measured elements can be used for testing when obtaining the temperature compensation value. For example, 2 to 3 measured elements are selected, and the average of the temperature compensation values ​​of the multiple measured elements is used as the final temperature compensation value of this type of measured element. Exemplarily, the final temperature compensation value of the measured element can also be stored. In subsequent tests, the same type of measured elements can directly use the stored temperature compensation value to avoid repeated calculations, which is also conducive to improving the efficiency of temperature compensation.

[0052] According to a temperature compensation method of the present application, an input signal is provided to the element under test to increase the temperature of the element under test, thereby obtaining the power offset of the element under test in different temperature ranges, thereby eliminating the intervention cost of an external temperature box and alleviating the tedious process of manually adjusting the external temperature box to obtain multiple internal temperature values.

The acquisition module 210 is used to acquire multiple internal temperature values ​​when the measured element processes an input signal, and the actual RF power of the measured element corresponding to each internal temperature value. The power offset calculation module 220 is used to calculate the power offset of the measured element at each internal temperature value according to each internal temperature value and its corresponding actual RF power. The compensation module 230 is used to perform power compensation on the measured element at different temperatures based on the power offset, so that the measured element maintains the output target RF power at different temperatures.

[0055] In some embodiments, the execution steps of the power offset calculation module 220 include: constructing a temperature compensation curve for characterizing the correspondence between the internal temperature value and the actual RF power based on each internal temperature value and its corresponding actual RF power; determining the temperature compensation slope of each temperature interval in the temperature compensation curve, wherein the temperature interval is used to characterize the temperature range between two internal temperature values ​​with adjacent values; and calculating the power offset of the measured element when it is at each internal temperature value based on each temperature compensation slope and its corresponding internal temperature value.

[0056] In some implementations, the power offset formula may be expressed as: Where M is the temperature compensation slope, T 1 is the normal temperature value, T 2 is the internal temperature value, D is the measured element at T 2 The power offset at .

[0057] In some embodiments, an input signal generating module (not shown) is further included, which is used to transmit an input signal of preset power to the measured element multiple times, so that the measured element generates multiple continuous internal temperature values ​​when processing the input signal.

[0059] According to a temperature compensation system of the present application, an input signal is provided to the element under test to increase the temperature of the element under test, thereby obtaining the power offset of the element under test in different temperature ranges, thereby eliminating the intervention cost of an external temperature box and alleviating the tedious process of manually adjusting the external temperature box to obtain multiple internal temperature values.
