Hi, here you can see 3-stage LNA circuit. I want to know information about two chips(6 pins) with R8 mark at the top. Also, 4 chips with D4 mark with 3 pins at right side. Is there anyone who has a good intuition of this?

\$\begingroup\$ Can you tell us about the part that these components are in? Perhaps a manufacturer and model number for the overall board/assembly? \$\endgroup\$– nanofaradMar 11, 2019 at 2:13
