Hello.

 

I have the next  hardware configuration:

 

AD8331 + AD8333 + AD8021 + Buffer + ADC (PCM4220).

 

Buffer schematic:

My device must  works with input signal level (~  - 120dBm).

 

1) Tell me please, buffer  hardware configuration is optimal for matching AD8021 and PCM4220 ?

2) Сan I get sensitivity near -120 dBm with using AD8333 demodulator ?

 

I am hope for your help.

Thanks.
