1. FMAT7467-7 Substitution Conclusion The FMAT7467-7 can serve as a substitute for the original part FMAT7620-7, subject to a strict frequency band limitation. The core difference lies in its operational frequency range, which is reduced from DC~18 GHz (original) to DC~12 GHz. This substitution is therefore only viable for systems with a maximum operating frequency not exceeding 12 GHz. If deployed within the 12 GHz to 18 GHz band, performance parameters such as attenuation accuracy and VSWR cannot be guaranteed, potentially leading to degraded system performance. In all other aspects—nominal attenuation value (7dB), impedance (50Ω), power handling capacity (2W), and connector interface (SMA In-Line)—the two parts are identical. Within the sub-12 GHz spectrum, it can be considered a direct drop-in replacement.
