1. FMAT7467-1 Substitution Conclusion
Based on core electrical parameters and mechanical interface, the FMAT7467-1 is a fully compatible substitute for the original LCAT1000-01 part. Both units are identical in their attenuation value (1 dB), power handling (2 W), impedance (50 Ω), and connector interface (SMA male-to-female in-line module). The key difference lies in the frequency range: the FMAT7467-1 supports 0–12 GHz, which is superior to the original part's 0–6 GHz. The substitute part maintains its specified attenuation accuracy and VSWR performance up to 12 GHz, whereas the original unit's performance may degrade beyond 6 GHz. Within the common operating band of up to 6 GHz, the substitute will deliver equivalent or better performance. Therefore, the substitution is not only feasible but also offers a performance enhancement.
2. LCAT1005-01 Substitution Conclusion
The LCAT1005-01, being an upgraded product from the original manufacturer L-com within the same series, represents a direct and superior replacement option. Its attenuation value, power rating, impedance, and interface are identical to those of the original part. The critical improvement is a significant extension of the frequency range, increased from 0–6 GHz to 0–18 GHz. This part incorporates a more refined internal structure and materials to maintain good impedance matching and attenuation flatness across the wider bandwidth. For applications below 6 GHz, it provides performance comparable to or more stable than the original. Furthermore, it enables operation in higher frequency bands—such as microwave communications and radar systems—where the original part was not capable. This substitute is fully compatible both electrically and mechanically and delivers a substantial upgrade in technical performance.
