1. LCAT1006-07 Substitution Conclusion The LCAT1006-07 is a direct and viable substitute for the original AT-107V, as it fully matches all key performance parameters. Both parts feature 7 dB attenuation, 2 W power handling, and 50 Ω impedance. Their frequency range identically covers DC to 18 GHz, and they share the same SMA straight-through module package. From an electrical performance and mechanical interface perspective, the LCAT1006-07 can be considered a functionally equivalent replacement. The primary difference lies in the manufacturer brand (L-com versus Hirose), which may impact supply chain availability and cost, but core functionality and performance are effectively identical.
