1. SA18H-09 Substitution Conclusion A direct, fully feasible, and performance-enhanced substitute. The SA18H-09 is fully consistent with the original LCAT1002-09 in all core electrical parameters (9dB attenuation, 2W power handling, 50Ω impedance) and mechanical package (SMA feedthrough module). Its key advantage lies in significantly extending the frequency range from DC-3GHz to DC-18GHz. The SA18H-09 provides fully compatible performance within the original design's sub-3GHz requirement, while the wider operational bandwidth offers the system additional frequency margin and potential for future upgrades to higher-frequency applications, typically without added cost. It is an ideal upgrade replacement.

2. FMAT1013 Substitution Conclusion A direct, fully feasible, and performance-equivalent substitute. The FMAT1013 matches all key specifications of the original LCAT1002-09—including attenuation value, power handling, impedance, and connector type—ensuring a drop-in replacement and functional consistency within the target system (operating below 3GHz). The difference is the extended frequency range from DC-3GHz to DC-6GHz. This extension provides improved performance margin (e.g., potentially better VSWR and accuracy stability) within the original 3GHz application band, while also supporting higher-frequency use cases. It offers a moderate frequency upgrade path for the system and represents a cost-effective alternative.
