1. FMAT7620-3 Substitution Conclusion The FMAT7620-3 can serve as a viable electrical substitute for the FMAT7467-3, though mechanical compatibility requires careful evaluation. Key differences include: - Frequency range: The FMAT7620-3 supports 0 Hz to 18 GHz, exceeding the original part’s 0 Hz to 12 GHz. This provides wider bandwidth and potential performance benefits in higher-frequency applications, making it suitable for system upgrades beyond 12 GHz. - Connector type: The FMAT7620-3 is specified as “SMA MALE,” whereas the original part is listed as “JACK-PLUG SMA 1.35.” This may indicate a difference in connector gender or configuration (e.g., male versus a male–female assembly). Actual interface matching should be verified to avoid physical connection issues during installation. Other parameters—including attenuation (3 dB), power rating (2 W), and impedance (50 Ω)—remain identical, ensuring direct replacement for basic electrical functionality. Provided connector compatibility is confirmed, substitution is feasible and can leverage the extended frequency capability.
