1. FMAT7620-8 Substitution Conclusion The FMAT7620-8 can serve as a complete drop-in replacement for the original FMAT7467-8 part. Both devices share identical core parameters, including an attenuation value of 8 dB, power rating of 2 W, 50 Ω impedance, and package footprint. Moreover, the FMAT7620-8 offers a frequency range of 0 Hz to 18 GHz, which fully covers and exceeds the original part’s range of 0 Hz to 12 GHz. This extended bandwidth enhances the substitute’s suitability for higher‑frequency applications, allowing it to be used not only in all existing scenarios but also potentially in systems operating at elevated frequencies. All other electrical characteristics and physical interfaces remain compatible, ensuring no performance degradation after substitution while providing improved bandwidth adaptability.
