1. FMAT7467-9 Substitution Conclusion
The attenuation, power handling, and impedance of this part are identical to the original part, and it shares the same SMA through‑module package. Therefore, it can serve as a functional equivalent for basic operation from DC to 12 GHz. The key distinction is its upper frequency limit of 12 GHz, which is notably lower than the original’s 18 GHz. If your application frequency exceeds 12 GHz—for instance, in Ku‑band or certain radar and test‑and‑measurement scenarios—this part is unsuitable and may introduce unknown insertion loss and performance degradation. It constitutes a frequency‑downgraded substitute. Replacement is acceptable only if the system’s maximum operating frequency is confirmed not to exceed 12 GHz; otherwise, it is not viable.
2. SA6H‑09 Substitution Conclusion
This part matches the original in core parameters such as attenuation, power rating, and impedance. However, its maximum operating frequency is only 6 GHz, representing a significant reduction from the original’s 18 GHz. It is suitable solely for mid‑to‑low‑frequency applications such as UHF, cellular communications, and WiFi. For any system operating in C‑band (4–8 GHz) or above, including Ku‑band (12–18 GHz), this part will either fail to function or exhibit severely degraded performance, making it a heavily frequency‑downgraded substitute. It cannot be used as a replacement unless the application is strictly confirmed to remain below 6 GHz.
