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
