RF Amplifiers Feature Summary

• Push-pull architecture designed for cable television applications
• High linearity performance with superior third-order intercept point
• GaAs technology ensuring stable operation at elevated temperatures

RF Amplifiers Applications

• Cable Television (CATV) signal distribution systems
• RF amplification stages in broadband networks
• Headend equipment requiring wideband linear amplification

RF Amplifiers Procurement Notes

Verify the specific package variant against the official datasheet, as distributor listings may reference alternative form factors like QFN despite the primary specification indicating SOIC-8. Confirm RoHS compliance status directly with the manufacturer documentation prior to integration. Ensure that the supply voltage requirements align with the system design, as the device operates at 24 V. Cross-reference the part number suffix to confirm tape and reel packaging specifications if automated assembly is planned.

RF Amplifiers Selection Notes

Select this component for designs requiring wideband amplification between 47 MHz and 1.218 GHz with high linearity. The 28 dB gain and 49.3 dBm OIP3 make it suitable for maintaining signal integrity in CATV infrastructure. Consider the 24 V operating voltage when designing power management circuits. The extended temperature range up to 100°C supports robust deployment in demanding environmental conditions typical of outdoor or industrial headend locations.
