1. SA18H-09 Substitution Conclusion Substitution is viable. The SA18H-09 is fully equivalent to the original FMAT7467-9 part in core parameters (attenuation value, impedance, power rating). Its primary technical advantage lies in its extended operational frequency range of 0-18 GHz, which completely covers and surpasses the original part's 0-12 GHz range. The SA18H-09 offers guaranteed performance in high-frequency applications up to 18 GHz and delivers equivalent or superior performance within the original design's sub-12 GHz spectrum. This constitutes a direct upgrade replacement, offering higher compatibility and reliability.

2. FMAT1013 Substitution Conclusion Substitution is feasible only under specific conditions and carries a downgrade risk. The key difference between the FMAT1013 and the original part is its operational frequency range, limited to 0-6 GHz, which is significantly narrower than the original's 0-12 GHz. If the host circuit operates above 6 GHz (even within the 12 GHz limit), using the FMAT1013 will likely cause abnormal signal attenuation, performance degradation, or even device failure. It may only be considered as a lower-cost downgrade alternative if it is definitively confirmed that the entire system's operational frequency never exceeds 6 GHz. Otherwise, substitution is not recommended.
