AI Technical Summary

Problems solved by technology

[0005] 1. The traditional transceiver front-end is divided into three independent modules: receiving, transmitting, and local oscillator. Each module has a single function, low integration, large system volume, and complicated circuit assembly;

[0006] 2. Traditional transceiver front-end devices have many types and quantities, and various assembly methods, which pose great challenges to reliability and stability in complex use environments;

[0007] 3. The local oscillator signal of the traditional transceiver front-end is generated by the conventional phase-locked loop mode, and the phase noise is low, which cannot meet the test requirements for the target test under the multi-beam test condition;

[0008] 4. The traditional way of sending and receiving has fewer front-end channels and a narrow range of use, so it cannot achieve multi-target and wide-scenario testing
