1. FMAT7626-6 Substitution Conclusion The FMAT7626-6 is a fully qualified drop-in replacement for the original SA6S10W-06 attenuator. Both units share identical core electrical and mechanical specifications: an attenuation value of 6 dB, a power rating of 10W, a 50Ω impedance, and an SMA in-line module package. This ensures direct compatibility in both electrical performance and physical mounting. The most significant technical distinction lies in the frequency range. The original part supports 0-6 GHz, whereas the FMAT7626-6 extends the upper frequency limit to 18 GHz. This represents a performance upgrade, as the substitute maintains specified performance across this wider bandwidth while fully encompassing the original unit's operational range. For systems operating at or below 6 GHz—the original part's intended range—the FMAT7626-6 provides equivalent functionality. Its extended frequency capability also offers potential for wider application. It is recommended to perform circuit verification prior to implementation to ensure no anomalies are introduced.
