1. FMAT7467-6 Substitution Conclusion The FMAT7467-6 matches the original AT-106V in all key parameters—attenuation (6 dB), power rating (2 W), and impedance (50 Ω). However, its operational frequency range (0–12 GHz) is narrower than that of the original part (0–18 GHz). This substitute can only be used in systems operating at or below 12 GHz. If the system operates between 12 GHz and 18 GHz, using this part will introduce unpredictable additional insertion loss and performance degradation, which may lead to signal distortion or failure to meet system specifications.

2. FMAT1012 Substitution Conclusion The FMAT1012 aligns with the original part in static parameters such as attenuation, power handling, and impedance. Nevertheless, its frequency range (0–6 GHz) is significantly narrower than the original’s 0–18 GHz. This substitute is only suitable for low-frequency applications (≤6 GHz), and its applicability is very limited. In any system operating above 6 GHz—including common bands such as C‑band satellite communications or X‑band radar—this replacement cannot guarantee proper attenuation accuracy and impedance matching, making system failure highly likely.
