we have been using BFU790F for our design since 2019. the weird thing we noticed is the board to board variation is too much. our LNA cant get consistent performance at all. did anyone see this problem? is this a known problem which has been fixed recently?
We are not aware about any problem with the BFU790F that would cause any performance degradation. Please note, the board performance may depend not only on the BFU790F itself but also on other components and your hardware design. We suggest our customers to go through one of our dedicated RF distributors such as Richardson RFPD and RFMW. We rely on their support for these types of inquiries as they would become more involved in the full design of the product.
