Design of an S Band Single-chip Digital Transceiver Unit

The digital radar transceiver includes functional units such as radio frequency transceiver frequency conversion, segmented filtering, radio frequency signal amplification and attenuation, digital to analog signal conversion etc. It has characteristics of high power, high bandwidth and array applications. The encapsulation of channel units will be beneficial for the assembly and debugging of radar transceiver equipment, and can reduce costs while achieving equipment miniaturization and light weighting. According to the requirements of S band single-chip radar transceiver, a design scheme of single-chip broadband digital transceiver unit is proposed in this paper, combined with system-in-package (SiP) technology, integrated passive device technology, and on-chip system technology. Based on that, the design of S band single-chip broadband digital transceiver unit is introduced. The design adopts various integration technologies such as chip integration, passive integration, SiP system integration, replacing the printed circuit board circuit originally composed of dozens of discrete components, which greatly reduces the types and quantities of components and improves digital transmission and reception performance.
