1. LCAT1001-06 Substitution Conclusion
The LCAT1001-06 is not a direct drop-in replacement for the original AT-106V. While both components are identical in attenuation value (6 dB), power handling (2 W), impedance (50 Ω), and connector type (SMA), their core difference lies in the frequency range: the LCAT1001-06 is only specified for 0–3 GHz, whereas the original part supports up to 18 GHz. Within the 3 GHz to 18 GHz band, the performance of the LCAT1001-06 cannot be guaranteed. Its attenuation may deviate significantly from the nominal value, VSWR may degrade, and additional insertion loss or signal distortion may be introduced. This can lead to substandard or even complete failure of the high-frequency link performance.
2. FMAT7620-6 Substitution Conclusion
The FMAT7620-6 is a viable direct replacement for the original AT-106V in terms of both electrical and mechanical specifications. All key parameters are fully matched, including attenuation (6 dB), frequency range (0–18 GHz), power handling (2 W), impedance (50 Ω), and interface type (SMA In-Line Module). Given this consistency, the FMAT7620-6 can deliver equivalent RF performance to the original part in the vast majority of applications—such as attenuation accuracy, frequency flatness, and power handling capability—without requiring circuit redesign or re-evaluation of the link budget.
