1. FMAT7620-3 Substitution Conclusion The FMAT7620-3 can fully replace the original part FMAT7466-3, as both share identical core parameters (3 dB attenuation, 2 W power handling, 50 Ω impedance, and package form). However, the FMAT7620-3 offers an extended frequency range up to 18 GHz, compared to the original part’s 12 GHz. This improvement enables the FMAT7620-3 to maintain performance at higher frequencies while remaining fully backward compatible with all original application scenarios. The difference only broadens the usable frequency range without imposing constraints on other characteristics. Therefore, the substitution is highly feasible and may enhance the system’s bandwidth adaptability.
