MMWCAS-RF-EVM: MMWCAS-RF-EVM(awr2243P)最大检测距离与IFmax和ADC_sample_rate的关系?

Part Number: MMWCAS-RF-EVM
Other Parts Discussed in Thread: AWR2243

www.ti.com/.../swra553a.pdf Range的描述如下:

其中描述到,在complex 1x采样模式下,IFmax受限于0.9*ADC_sample_rate,那是否意味着在实际计算Range_max的公式中IFmax=min(20MHz, 0.9*ADC_sample_rate)?而不是取IFmax=ADC_sample_rate?因为在TI的其他文档中,如下图所示,常常使用IFmax=ADC_sample_rate,是否这里引起了混淆?

在AWR2243芯片手册https://www.ti.com/lit/ds/symlink/awr2243.pdf?ts=1625747946527&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FAWR2243中可查询:

是否意味着:当我设置ADC_sample_rate至最大22.5Msps, 在计算Rmax的时候,IFmax=min(20MHz, 0.9*22.5Msps=20.25Msps)=20MHz?
