1. FMAT7620-10 Substitution Conclusion From the perspective of core electrical parameters and mechanical specifications, the FMAT7620-10 can serve as a direct replacement for the FMAT7467-10. Both parts are identical in key attributes: attenuation value (10 dB), rated power (2W), impedance (50 Ω), and package type (SMA inline module), ensuring functional equivalence. The primary technical distinction lies in the frequency range: the FMAT7620-10 extends the upper limit from 12 GHz to 18 GHz. The new part offers superior broadband RF performance, maintaining specified attenuation accuracy and matching characteristics up to the higher frequency band (12–18 GHz), whereas the original part's performance in this range may not be specified or may degrade. Substitution is not only feasible but represents an electrical performance upgrade, provided the connector gender (SMA male) matches the corresponding interface in the existing system for seamless integration.
