1. LCAT1002-07 Substitution Conclusion
The substitution of the LCAT1002-07 for the original part is subject to limitations. The key deviation lies in its frequency range (0–3 GHz), which is significantly narrower than the original part's 0–12 GHz. Within the 3 GHz to 12 GHz operating band, the LCAT1002-07 may exhibit severe degradation in attenuation accuracy, impedance matching, and power handling capability. This could lead to system signal distortion, increased reflection, or potential device damage. Therefore, it can only safely replace the original part in low-frequency applications not exceeding 3 GHz. Substitution is not viable beyond this range.
2. FMAT7620-7 Substitution Conclusion
The FMAT7620-7 serves as a direct and superior replacement for the original part. Its primary technical advantage is a frequency range (0–18 GHz) that fully covers and exceeds the original part's 0–12 GHz. Across the entire operational bandwidth of the original part, the FMAT7620-7 delivers equivalent or better electrical performance, such as in attenuation flatness and VSWR, while offering potential for extended use in higher frequency applications (12–18 GHz). Both parts are identical in attenuation value, power rating, and interface configuration. Consequently, the FMAT7620-7 represents an ideal, upward-compatible substitute.
