We propose a 1 &#x00D7; 32 silicon photonics transceiver integrated optical phased array (OPA) with a large scanning angle. It can process receive and transmit signals simultaneously, which effectively increases the on-chip signal transmission efficiency. The simulation shows that the phase-tuned 62.2&#x00B0; lateral beam steering without grating lobe and the wavelength-tuned 31.2&#x00B0; longitudinal beam steering can be achieved in the transmitting mode, and the overall optical loss is less than 9.1 dB. In the receiving mode, the combination of the two detection methods reduces the complexity of the system while ensuring the sensitivity of the system. According to statistics, an effective collection area of 43.3&#x0025; per unit area can be achieved in the receiving mode, which provides a reliable guarantee for subsequent high-quality signal processing.
