Hi Team,
Generally speaking, receivers have some related indicators, such as adjacent channel suppression, and in-band blocking. For superheterodyne, low-IF or zero-IF receivers, the signals in the RF band can be filtered by IF filters. But for direct RF sampling, how can we solve this problem? For example, AFE7686 is RF direct sampling. When it is used in 3G or 4G, how can we meet the technical indicators required by the specification?
Thanks.
