1. FMAT7620-7 Substitution Conclusion The FMAT7620-7 can fully replace the original part LCAT1000-07. Its core advantage lies in extending the effective operating frequency range from 0–6 GHz to 0–18 GHz. This device adopts a higher-frequency broadband design, superior RF materials, and a more precise internal structure, enabling stable attenuation performance and impedance matching up to 18 GHz in the millimeter-wave band. Within the common operating range of 6 GHz and below, both parts exhibit identical key parameters—including attenuation (7 dB), power handling (2 W), and impedance (50 Ω)—and share the same SMA male in-line module interface, ensuring direct physical and electrical compatibility. The FMAT7620-7 not only covers all application scenarios of the original part (such as wireless communications and test systems), but is also suitable for higher-frequency microwave systems, representing a direct performance upgrade and replacement.
