射频与混合信号
R2026bMATLAB® 和 Simulink® 产品为工程师提供了更高层的抽象，可以在统一平台上以更高的速度和保真度实现射频和混合信号系统。工程师可以：
使用 S 参数、物理属性或规格书等测量数据，对射频和天线单元、射频收发机和前端以及 RF PCB 进行建模。
开发模拟和混合信号组件，如 ADC、DAC、PLL、电源转换器和 SerDes 系统，并为高速数字互连生成 IBIS-AMI 模型。
生成并分析方向图失真，计算阻抗不匹配，执行射频预算分析，拟合 S 参数数据，并可视化天线覆盖率。
观察 ISI、抖动、噪声、插入损耗、回波损耗和串扰的影响，验证通道是否符合 IEEE 802.3、OIF、PCle 和 DDR 等行业标准。
