1. FMAT7611-12 Substitution Conclusion
From a core electrical parameter standpoint, the FMAT7611-12 is a fully qualified substitute for the original FMAT1014 part. The key difference lies in its extended frequency range of 0-18 GHz (compared to 0-6 GHz for the original). This part maintains the specified 12dB attenuation accuracy and 2W power handling capability even at higher frequencies, such as in Ku-band applications, while offering full backward compatibility with no performance degradation in the original sub-6GHz operating range. Additionally, its interface is explicitly defined as an SMA Male connector. In contrast, the original part was described as "PLUG-JACK," typically indicating a structure with one male pin and one female jack. This mechanical interface difference necessitates verification of connector gender compatibility within the existing link during direct substitution. Failure to do so may require the use of an appropriate adapter or a change in the connection scheme.
2. FMAT7620-12 Substitution Conclusion
The FMAT7620-12 is also an electrically suitable replacement for the original FMAT1014. Its parameters are identical to those of the FMAT7611-12, with the differences similarly being the wider frequency range (0-18 GHz) and the SMA Male interface form factor. The frequency extension makes this component suitable for a broader range of RF and microwave applications, while its performance remains equivalent to the original within the 6GHz and lower bands. The interface type discrepancy requires confirmation of physical connection compatibility during the design substitution. If the original system utilized the conversion functionality of a "PLUG-JACK" structure, directly implementing an SMA Male attenuator may alter the connection path, necessitating evaluation of an appropriate adaptation solution.
