I have a signal with a DC voltage around 2V ( as it's used in receiver side, the DC is determined by power detector output and is varying between 0.2 to 2 V) the freequency is 200kHz-10MHz and the AC voltage is 13-15mV . I want to retrieve the pulse using an ADC. I want to know which ADC (or comparator) can be used? The attachment you can find one example of my signal at the output of RF front-end. In this example, the signal at the input RF front-end is a 200KHz pulse with 50% duty cycle. The desired output would be with VH=1.2V and VL=0 V. I tried to use AD8611 with dc bloc cap (1uF) but It didn't work...
Thanks in advance,
