Video Amps And Modules Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest product specification to ensure compatibility with required packaging or tape-and-reel configurations. Confirm that the device status remains active for production use, as datasheet revisions may impact availability or minor physical attributes. Cross-reference the SOT115J package dimensions during PCB layout finalization.

Video Amps And Modules Selection Notes

Select this module for applications requiring high gain and low noise in cable TV infrastructure. Ensure the design accommodates a 24 V DC supply capable of delivering up to 340 mA. Verify thermal management capabilities, as the mounting base temperature must remain within specified limits. Confirm system impedance matches the 75-ohm requirement for optimal return loss performance.
