The present invention relates to the technical field of radome electrical performance test and to an X-band test module structure. The module structure includes a power amplifier and an absorbing structure; the power amplifier is connected to an output of a vector network analyzer, and the power amplifier uniformly amplifies power of intermediate frequency signals sent by the vector network analyzer; the absorbing structure and the output of the power amplifier is connected, and the absorbing structure outputs signals amplified by the power amplifier to 0 to 6 dB in the X-band; an intermediatefrequency unit mixer is connected to an output end of the absorbing structure, and output signals of the absorbing structure enter the intermediate frequency unit mixer to make signals of the mixer reach a stable working state. The structure makes power of the X-band enter the intermediate frequency unit mixer between 0 and 6 dB, to satisfies a power range of the intermediate frequency unit mixer, make test signals more stable, achieve an ideal test state, and to make test data more accurate and reliable.
Description
technical field [0001] The invention belongs to the technical field of radome electrical performance testing and relates to an X-band testing module structure. Background technique [0002] In the process of testing a radome, the intermediate frequency signal sent by the test system from the vector network analyzer enters through the intermediate frequency unit mixer; the intermediate frequency signal acts as a reference, allowing it to reach a relative ratio, making the signal more stable. However, the intermediate frequency signal sent by the vector network analyzer is very small, which cannot reach the ideal range (0 ~ 6dB) of the signal received by the intermediate frequency unit mixer, so it cannot play its due reference role. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an X-band test module structure, which converts the intermediate frequency signal sent by the vector network analyzer to between 0 and 6...
