Hi,
I find out a good tool in TI; https://www.ti.com/tool/FREQ-DDC-FILTER-CALC
I set Fs=2900MHz, Interleave=1, Fc=2050MHz, BW=1MHz.
I get: Rx band=850MHz, HD2=1200MHz, HD3=350MHz, HD4=500MHz, HD5=1350MHz
"slyt738.pdf" The TI doc. show HD2 is 2nd harmonic. I'm confuse it; Fc=2050MHz, 2nd Harmonic= 4100MHz. Does it correct??
Could you share how to calculate the frequency of Rx band, HD2~HD5, HD2 ~HD3 image, IL??
Could I use the tool to design the under-sampling ADC ??
