1. SA18E-09 Substitution Conclusion The SA18E-09 is a fully qualified substitute for the original LCAT1001-09. Both parts share identical core specifications: 9dB attenuation, 2W power handling, 50Ω impedance, and SMA connectors. The key distinction is the frequency range: the SA18E-09 operates from DC to 18 GHz, significantly wider than the original's DC to 3 GHz range. The SA18E-09 maintains its rated attenuation performance and impedance matching up to 18 GHz. Its superior bandwidth performance means it will deliver equivalent or better electrical characteristics within the original part's operational range of 3 GHz and below. Compatibility and reliability are assured, making it a high-performance replacement option.

2. FMAT7467-9 Substitution Conclusion The FMAT7467-9 is also a complete and direct replacement for the original LCAT1001-09. Its core electrical specifications (9dB, 2W, 50Ω, SMA) are identical to the original. The primary difference is its extended frequency range of DC to 12 GHz, compared to the original's DC to 3 GHz. This indicates the FMAT7467-9 is optimized for performance over a wider bandwidth, particularly in the 3 GHz to 12 GHz range. Within the original's operating band of 3 GHz and below, its attenuation accuracy, VSWR, and other key parameters are expected to meet or exceed the original requirements, ensuring full downward compatibility. It serves as a reliable drop-in replacement while providing additional bandwidth headroom for potential future system upgrades.
