1. FMAT7467-10 Substitution Conclusion
The FMAT7467-10 matches the original AT-110V part in core specifications such as power handling and impedance. However, a key difference lies in the operational frequency range: the FMAT7467-10 covers 0–12 GHz, whereas the AT-110V supports 0–18 GHz. If your application operates below 12 GHz, the FMAT7467-10 serves as a viable drop-in replacement with no significant performance degradation. For systems operating above 12 GHz up to 18 GHz, using this substitute will lead to unstable attenuation, performance degradation, or outright failure; therefore, it is not a suitable replacement in this higher frequency band. Additionally, note that its interface is described as “JACK-PLUG,” which may differ in gender or configuration from the original module’s connector. Verify mechanical compatibility during installation.
2. SA3SR-10 Substitution Conclusion
The SA3SR-10 aligns with the original AT-110V in attenuation value, power rating, and impedance. Its operational frequency range, however, is limited to 0–3 GHz, significantly lower than the original part’s 18 GHz. The SA3SR-10 is only suitable for low-frequency applications, such as general RF communications or low-frequency testing. If used in circuits or systems operating at higher frequencies—especially above 3 GHz—it will introduce unacceptable insertion loss and performance deterioration, completely failing to replicate the high-frequency performance of the original part. Consequently, it is not a feasible substitute for high-frequency applications. Similarly, its “PLUG-JACK” interface configuration may differ from that of the original part; physical connector compatibility should be verified prior to substitution.
