1. FMAT1010 Substitution Conclusion The FMAT1010 can serve as a full and direct replacement for the original LCAT1000-03 part. Its key electrical and mechanical specifications—including 3 dB attenuation, a frequency range of DC-6 GHz, 2W power handling, 50Ω impedance, and SMA coaxial construction—are identical to those of the original part. Within the target application band (up to 6 GHz), it provides equivalent electrical performance, power handling capability, and connector compatibility, enabling a lossless substitution as a drop-in replacement of the same specification.

2. FMAT7466-3 Substitution Conclusion The FMAT7466-3 is a suitable replacement for the original LCAT1000-03, offering additional performance margin. The primary difference lies in its extended frequency range of up to 12 GHz, which significantly exceeds the original part’s 6 GHz limit. Its internal circuit design and materials provide enhanced high-frequency signal handling capability. When used within the original 6 GHz and lower frequency bands, the FMAT7466-3 delivers higher performance headroom. Mechanical interfaces and fundamental electrical parameters—attenuation, power rating, and impedance—remain unchanged, ensuring full system compatibility. This substitution also offers greater bandwidth adaptability for future requirements.
