摘要
A phased-array transmitter includes a first PLL for transmission, a control circuit, a plurality of transmission units, a delay circuit, and a second PLL for self-test. The first PLL is configured to generate a reference transmission signal, and the control circuit is configured to control the first PLL. The transmission units are configured to receive the reference transmission signal, and perform amplification and phase control to output unit transmission waves, respectively. The delay circuit is configured to delay a signal based on the reference transmission signal, and the second PLL is configured to receive an output signal of the delay circuit, and generate a self-test signal for performing self-test.
