AWR6843AOP数据手册开发板套件编程器的射频评估开发套件开发板规格书PDF

描述 Description

The AWR6843AOP is an Antenna-on-Package (AOP) device that is an evolution within the single-chip radar device family from Texas Instruments (TI). This device enables unprecedented levels of integration in an extremely small form factor and is an ideal solution for low power, self-monitored, ultra-accurate radar systems in the Automtive space.Multiple automotive qualified variants are currently available including Functional Safety-Compliant targeted devices and non-functional safety devices.
