The Study Of Dedicated Wireless PA Module For Shock Wave Test Systems

Blast weapons are an important anti-factors and weapons testing study. The wire- less technology used in the field of shock wave memory test has its advantages. In the field of shock wave wireless system, transmission distance is important parameters. So the power amplifier and receiver low-noise power amplifier circuit is necessary. The power amplifier module is to enhance the launch of the main signal power to increase the effective transmission distance and lower noise; low-noise amplifier circuit module to receive weak signals from the channel, improve system sensitivity. The effectiveness has a positive impact on the transmission distance.In order to avoid the skin effect, radiation effect, the impact of parasitic capacitance inductance,make the transmitter to the maximum energy transfer to the receiving end and increase effective transmission distance, the device external matching circuit is especially necessary.Based on the 2.4GHz low-noise amplifier parts, designing the external matching for low-noise amplifier, analyzing the effectiveness of the match circuit; finally under different conditions, Vector Network Analyzer instrument is made use of testing its low-noise power amplifier module performance. We also test the Power amplifier module by the vector network analyzer to get measurement parameters.Analysis shows that matching circuits improve circuit performance, improving the market explosion shock wave in wireless transceiver system has great significance.
