Description

technical field [0001] The invention relates to the field of microwave and millimeter wave solid-state power amplifiers, in particular to an adjustable power equalizer with combined links. Background technique [0002] The development of microwave and millimeter-wave solid-state power amplifier technology has put forward higher requirements for power equalization technology. Not only does the equalizer need to achieve power equalization at more frequency points, it needs to have a larger power amplitude equalization range, but also requires the ability to balance power The signal transmission phase of the equalizer can be effectively adjusted, which brings greater challenges to the design of the equalizer. Due to problems such as material consistency, there is often a certain deviation between the measured results of the equalizer and the simulated results, and it is difficult to adjust the finished product. Therefore, it often takes multiple board tests to obtain the final ...

Problems solved by technology

Due to problems such as material consistency, there is often a certain deviation between the measured results of the equalizer and the simulated results, and it is difficult to adjust the finished product. Therefore, it often takes multiple board tests to obtain the final required equalizer indicators, resulting in a lot of repetitive work and increasing design cost

[0003] Conventional power equalizers generally adopt one-time processing and forming, and the adjustable range is limited, such as figure 1 As shown, in general, it is only possible to fine-tune by connecting the branch extension line with a gold mesh. Due to consistency problems such as materials and assembly, there is often a large deviation between the equalizer simulation and the actual test results. Therefore, in order to obtain the ideal equalization effect, It is often necessary to repeatedly put into production several times according to the actual test to obtain the required equalizer. This experiment and debugging process has caused a lot of repeated work and increased the cost of the design.

Traditional finished equalizers are difficult to effectively adjust the equalization frequency, amplitude and phase, and the universal applicability is poor
