Video Amps And Modules Procurement Notes

Verify the specific revision status of the datasheet before design implementation, as product specifications may change over time. Confirm that the application environment does not exceed the absolute maximum ratings defined in the limiting values section. Ensure proper thermal management is provided for the mounting base temperature, which ranges from -20°C to +100°C during operation. Validate that the 24 V DC supply aligns with the system requirements.

Video Amps And Modules Selection Notes

Select this component for applications requiring a compact hybrid amplifier solution with adjustable bias current. The SOT115AE package facilitates mounting via vertical holes and includes an aluminum flange for heat dissipation. Consider the specific impedance matching requirements, as the device is designed for 75 Ω source and load impedances. Evaluate the noise figure and distortion metrics against the CATV signal quality standards required for the target deployment.
