A multi-layer PCB with a solid ground plane and a separate power plane is recommended. Use a star-grounding scheme and keep the signal traces away from the power traces to minimize noise and radiation.
Use the device's built-in bias tees and adjust the bias voltage and current to optimize the amplifier's performance for the desired frequency range. Consult the application note AN-60-014 for more information.
The maximum safe operating temperature for the GALI-S66+ is 85°C. Operating the device above this temperature may reduce its reliability and lifespan.
Yes, the GALI-S66+ can be used in a push-pull configuration to improve its linearity and reduce distortion. However, this requires careful impedance matching and biasing to ensure optimal performance.
Check the PCB layout and grounding scheme for any issues. Ensure that the device is properly biased and that the input and output impedances are matched. Consult the application note AN-60-014 for troubleshooting guidelines.
