Problems solved by technology
[0004] Due to the complex functions and many circuits involved, the volume and weight of T / R components are difficult to meet the requirements when using traditional discrete device methods for circuit design.
Moreover, due to the large demand and complex production process, it is difficult to ensure consistency in the design, processing, production, and assembly processes, so the performance consistency of T / R components is poor

Embodiment Construction
[0010] The analog channel module is the core component of the entire T / R assembly, which consists of two channels: receiving and transmitting. The radio frequency weak signal received by the antenna is sent to the back-end AD through the circulator, limiting amplification, frequency selection filter bank, double frequency conversion amplification, intermediate frequency filtering and differential conversion circuit output with a certain amplitude differential intermediate frequency signal; transmit the intermediate frequency signal First, it is transformed into a single-ended signal through differential synthesis, then through intermediate frequency filtering, double frequency conversion amplification, frequency selection filter bank, and finally through power amplification and circulator, output RF signal to the antenna.
[0011] attached figure 1 It is a block diagram for the realization of the principle of the transceiver channel of the TR component, and the interior is div...

The invention relates to a system-on-a-chip integrated design method for an S-band 16-channel T / R module. By the adoption of the system-on-a-chip integrated design method for designing the S-band 16-channel T / R module, the internal functions of the T / R module are partitioned, some functions are integrated, and then the some functions are achieved on the same the chip through the system-on-a-chip integrated design method. By using the method for designing the module, the number of devices is reduced, the size of a module circuit is reduced, the weight is reduced, and circuits produced in a mass mode are good in uniformity; meanwhile, as the number of the devices is reduced, interconnection of the circuit devices is reduced, and the reliability of the module is improved; in comparison with the method of adopting a discrete device for designing the module, by the adoption of the system-on-a-chip integrated design, the size of the T / R module is reduced by 50%, and the weight is reduced by 60%.
Description
technical field [0001] The invention belongs to the design method technology of TR components in a phased array radar, and relates to an S-band 16-channel T / R component on-chip system integration design method. Background technique [0002] With the increase of the types of radar observation targets, the target parameters measured by radar are required to increase continuously and the ability of radar electronic countermeasures and target recognition is improved. Active digital phased array radar (APAR) is an important direction of radar development at present, and T / The R component is the core component of the phased array radar. [0003] In order to improve the overall performance of the radar, a phased array radar contains thousands or even tens of thousands of T / R components. As an important part of the radar, the volume, weight, performance, cost and reliability of the T / R components directly determine performance of the entire radar. Driven by the demand for an inte...
