Embodiment Construction
[0022] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0023] Such as figure 1 Shown, a kind of multi-channel digital TR assembly, it comprises FPGA chip, system clock network, ADC chip, DAC digital-to-analog conversion chip, gain controller, receiving interface and transmitting interface, and described receiving interface receives intermediate frequency signal and transmits to The ADC chip converts the digital signal and transmits it to the FPGA chip. The FPGA chip completes the digital down-conversion processing of the 8-channel received signal, and finally sends out the processed signal; at the same time, the FPGA chip receives the digital beamforming signal and completes the comprehensive processing of the 8-channel transmitted signal. , Send the digital signal to 2 DAC digital-to-analog co...
