Conditioning device for transmitting excitation signal in T/R assembly test system

Abstract

The invention provides a conditioning device for a transmitting excitation signal in a T/R assembly test system. The conditioning device comprises a T/R assembly, a switch network, a vector network analyzer and a signal generator. The switch network is connected with the signal generator, the vector network analyzer and the T/R assembly; the switch network comprises an amplifier, a control module and a plurality of switches; and the control module is connected with the amplifier and the switches. A jumper wire connected at source ports of the vector network analyzer is disassembled; the source output end and the source input end of the vector network analyzer are connected through two single-pole double-throw switches; a second amplifier is connected between the two single-pole double-throw switches; in such mode, the amplifier is introduced to the input end of a reference directional coupler arranged in the vector network analyzer, so that when the vector network analyzer is an emission source of the excitation signal, the power of the output excitation signal is enlarged, and meanwhile, calibration of the full two-ports and test of reflection parameters are guaranteed, and accuracy of the transmission parameter test is improved favorably.

Description

technical field [0001] The invention relates to the field of T / R component testing, in particular to a conditioning device for transmitting excitation signals in a T / R component testing system. Background technique [0002] T / R components are generally composed of one or more signal transceiving channels. T / R components are located in the RF microwave front-end of phased array electronic information equipment such as radar and electronic countermeasures. An important class of microwave components, which has a vital impact on the performance of the entire equipment, is also a typical representative of the field of microwave components. In addition, from the perspective of testing, it is a type of microwave component with the most testing parameters and the most complicated testing implementation. [0003] When testing the performance parameters of T / R components in the emission state, the power of the emission excitation signal is often insufficient due to the insufficient o...

Problems solved by technology

[0009] For the existing T / R component test system, when the source in the vector network analyzer is used as the excitation source, full dual two-port calibration cannot be performed, accurate transmission parameter test results cannot be obtained, and no power amplification is required at the system source output When the amplifier needs to be removed manually, the test efficiency is low and the cost is high.
