title: Analog Devices ADL8113 Low Noise Amplifier with integrated bypass switches

maintainers:
  - Antoniu Miclaus <antoniu.miclaus@analog.com>

description: |
  The ADL8113 is a 10MHz to 12GHz Low Noise Amplifier with integrated bypass
  switches controlled by two GPIO pins (VA and VB). The device supports four
  operation modes:
    - Internal Amplifier: VA=0, VB=0 - Signal passes through the internal LNA
    - Internal Bypass: VA=1, VB=1 - Signal bypasses through internal path
    - External Bypass A: VA=0, VB=1 - Signal routes from RFIN to OUT_A and from IN_A to RFOUT
    - External Bypass B: VA=1, VB=0 - Signal routes from RFIN to OUT_B and from IN_B to RFOUT

  adi,external-bypass-a-gain-db:
    description:
      Gain in dB of external amplifier connected to bypass path A (OUT_A/IN_A).
      When specified, this gain value becomes selectable via the hardwaregain
      attribute and automatically routes through the external A path.

  adi,external-bypass-b-gain-db:
    description:
      Gain in dB of external amplifier connected to bypass path B (OUT_B/IN_B).
      When specified, this gain value becomes selectable via the hardwaregain
      attribute and automatically routes through the external B path.
