1. FMAT7467-8 Substitution Conclusion
The FMAT7467-8 can serve as a substitute for the original FMAT7620-8, with the primary limitation being its narrower applicable frequency range. Specifically, both parts share identical attenuation (8 dB), power handling (2 W), impedance (50 Ω), and connector type (SMA In‑Line). The key difference lies in the frequency coverage: the FMAT7467-8 operates from 0 to 12 GHz, whereas the original part supports 0–18 GHz. If the application involves frequencies above 12 GHz (e.g., portions of the Ku‑band), the substitute may introduce additional insertion‑loss deviation or VSWR degradation, adversely affecting high‑frequency system performance. For operation below 12 GHz, direct substitution is acceptable.
2. LCAT1002-08 Substitution Conclusion
The LCAT1002-08 is not a practical substitute for the original FMAT7620-8, primarily due to its substantially reduced frequency range. While attenuation, power rating, and interface are the same, the LCAT1002-08 is limited to 0–3 GHz, far below the original’s 0–18 GHz coverage. This part is only suitable for low‑frequency or narrowband applications (such as cellular or WiFi). If used at higher frequencies (e.g., C‑, X‑, or Ku‑band), its attenuation accuracy, impedance matching, and power‑handling capability may deviate significantly from specified values, leading to signal distortion, increased reflection, or even device failure. Therefore, it is not recommended for direct replacement in broadband or high‑frequency systems.
