数模转换器和调制器接口电路的设计

Mobile terminal test set needs high performance RF transmitter. The DAC modulator interface circuit should be designed carefully. The DAC princeple was introduced firstly in this article. Secondly, based on the specific requirements, a DAC modulator interface circuit design solution based on the DAC chip was introduced, consists of requirement analysis, coupling selection, DC bias and resistance match, filter selection and the simulation result.
