13
  The ADL8113 is a 10MHz to 12GHz Low Noise Amplifier with integrated bypass

14
  switches controlled by two GPIO pins (VA and VB). The device supports four

15
  operation modes:

16
    - Internal Amplifier: VA=0, VB=0 - Signal passes through the internal LNA

17
    - Internal Bypass: VA=1, VB=1 - Signal bypasses through internal path

18
    - External Bypass A: VA=0, VB=1 - Signal routes from RFIN to OUT_A and from IN_A to RFOUT

19
    - External Bypass B: VA=1, VB=0 - Signal routes from RFIN to OUT_B and from IN_B to RFOUT
