Description

Technical Field

[0001] This utility model relates to the field of signal transmitting equipment technology, specifically to a 1:1 whole-machine hot backup power amplifier. Background Technology

[0002] Power amplifiers are crucial components of microwave transmission systems. Their function is to amplify useful low-power signals to a certain power level before they are transmitted via antennas. Power amplifiers have always been key microwave devices in electronic systems such as wireless communication, electronic warfare, and microwave measurement, and have extensive military and civilian applications.

[0003] In a complete communication system, the power amplifier plays a crucial role as a vital component and key module. However, the low efficiency and high heat generation of power amplifiers limit their inherently low reliability, significantly reducing the overall system reliability. As wireless communication demands ever-increasing system reliability, improving the reliability of power amplifiers has become both a key focus and a significant challenge.

[0004] There is currently no effective solution to the above problems. Utility Model Content

[0005] In view of the above-mentioned technical problems in related technologies, this utility model proposes a 1:1 whole-machine hot backup power amplifier, which can overcome the above-mentioned shortcomings of the prior art.

[0006] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:

[0007] A 1:1 whole-system hot-backup power amplifier includes a first switching module for RF signal input, which is connected to the beginning of a first path and a second path respectively. The end of the first path and the end of the second path are both connected to a second switching module. The second switching module is connected to a reflection power detection module for RF signal output through a filter module. The first path is communicatively connected to a first path status detection module, and the second path is communicatively connected to a second path status detection module. Both the first path status detection module and the second path status detection module are connected to a data processing module. The first path and the second path have the same structure and connection relationship.

[0008] Furthermore, the first path consists of, from beginning to end, a first path small signal amplification module, a first path filtering module one, a first path drive amplification module, a first path filtering module two, a first path high power amplification module, and a first path forward output power detection module.

[0009] Furthermore, the second path consists of, from beginning to end, the second path small signal amplification module II, the second path filtering module I, the second path drive amplification module II, the second path filtering module II, the second path high power amplification module II, and the second path forward output power detection module II.

[0010] Furthermore, the first path is the primary path, and the second path is the backup path. When the first path is abnormal, the data processing module will automatically switch the device to work on the second path.

[0011] The beneficial effects of this utility model are as follows: By implementing a 1:1 hot backup for the power amplifier, this utility model reduces the risk of failure when the whole system is performing tasks due to the low reliability of the power amplifier, thereby improving the reliability of the whole system.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0016] like Figure 1As shown in the embodiment of this utility model, a 1:1 whole-machine hot backup power amplifier includes a first switch module 1 for radio frequency signal input. The first switch module 1 is connected to the beginning of a first path and a second path respectively. The end of the first path and the end of the second path are both connected to a second switch module 14. The second switch module 14 is connected to a reflection power detection module 16 for radio frequency signal output through a filter module 15. The first path is communicatively connected to a first path status detection module, and the second path is communicatively connected to a second path status detection module. Both the first path status detection module and the second path status detection module are connected to a data processing module 17. The first path and the second path have the same structure and connection relationship.

[0017] The first path consists of, from beginning to end, the first path small signal amplification module 2, the first path filtering module one 3, the first path drive amplification module 4, the first path filtering module two 5, the first path high power amplification module 6, and the first path forward output power detection module 7.

[0018] The second path consists of, from beginning to end, the second path small signal amplification module 2 8, the second path filtering module 1 9, the second path drive amplification module 2 10, the second path filtering module 2 11, the second path high power amplification module 2 12, and the second path forward output power detection module 2 13.

[0019] The first path status detection module includes operating voltage detection, operating current detection, operating temperature detection, forward output power detection, and reflected power detection. The second path status detection module includes operating voltage detection, operating current detection, operating temperature detection, forward output power detection, and reflected power detection.

[0020] The RF signal input passes through the first switch and is sent to the first path. After passing through the first path small signal amplification module, the first path filter module one, the first path drive amplification module, the first path filter module two, the first path high power amplification module, and the first path forward output power detection module, it is sent to the second switch module. The filter module then passes through the reflection power detection module for RF signal output.

[0021] When the first path malfunctions, the system switches to the second path. The RF signal input passes through the first switch and is sent to the second path. After passing through the second path small signal amplification module, the second path filter module one, the second path drive amplification module, the second path filter module two, the second path high power amplification module, and the second path forward output power detection module, the signal is sent to the second switch module. The filter module then passes through the reflection power detection module for RF signal output.

[0022] The data processing module collects the status detection data of the first path and the status detection data of the second path.

[0023] The first path is the primary path, and the second path is the backup path. The primary path takes priority. When the data processing module detects an abnormality in the first path, the device automatically switches to the second path and reports the abnormal status of the first path to the upstream device. The status of the first and second paths includes operating voltage, operating current, operating temperature, forward output power, and reflected power. If the first path malfunctions, the device switches to the second path within a very short time.

[0024] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.

[0025] In practical use, according to the 1:1 whole-machine hot backup power amplifier described in this utility model, the RF signal input passes through the first switching module 1, and is sent to the first channel small signal amplification module 2. It then sequentially passes through the first channel filter module 1 3, the first channel drive amplification module 4, the first channel filter module 2 5, the first channel high-power amplification module 6, and the first channel forward output power detection module 7. Finally, it passes through the second switching module 14, the filter module 15, and the reflection power detection module 16 before the RF signal is output. When an abnormal state occurs in the first channel, the data processing module sends the RF signal input through the first switching module 1 to the second channel small signal amplification module 8. This then sequentially passes through the second channel filter module 1 9, the second channel drive amplification module 10, the second channel filter module 2 11, the second channel high-power amplification module 12, and the second channel forward output power detection module 13. Finally, it passes through the second switching module 14, the filter module 15, and the reflection power detection module 16 before the RF signal is output. The abnormal states of the first channel include: abnormal forward output power, abnormal operating voltage, abnormal operating current, abnormal operating temperature, and abnormal reflection power.

[0026] In summary, by utilizing the above-mentioned technical solution of this utility model, this utility model reduces the risk of failure of the whole system when performing tasks due to the low reliability of the power amplifier by using a 1:1 hot backup of the power amplifier, thereby improving the reliability of the whole system.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
