Alternative Part
1. FMAT7611-12 Substitution Conclusion
From the perspective of core electrical parameters and mechanical interface, the FMAT7611-12 can serve as a replacement for the original SA6H-12 part. Both components share identical specifications for attenuation value (12 dB), impedance (50 Ω), rated power (2 W), and package type (straight SMA module), ensuring direct compatibility for basic functionality. The key difference lies in the frequency range. The FMAT7611-12 supports 0-18 GHz, which is significantly wider than the original part's 0-6 GHz range. It performs equivalently to the original part at 6 GHz and below, while also possessing the capability to operate normally at higher frequencies (6-18 GHz). Typically, performance metrics such as Voltage Standing Wave Ratio (VSWR) in these higher bands are superior to those of the original part, which was only designed up to 6 GHz. Therefore, the substitution is technically fully viable and offers a redundant improvement in bandwidth performance.
2. FMAT7620-12 Substitution Conclusion
The FMAT7620-12 also presents a viable direct replacement for the original SA6H-12. Its critical parameters—attenuation, impedance, power rating, and interface—are identical to the original part, guaranteeing seamless substitution for the core functionality. The primary distinction, similar to the FMAT7611-12, is its wider operational frequency range (0-18 GHz versus 0-6 GHz). While fully covering and compatible with all application frequencies of the original part, the FMAT7620-12 offers the flexibility to extend into higher frequency bands. Furthermore, its design typically features more optimized and flatter attenuation and VSWR characteristics across the entire DC-18 GHz range. This part is not only a feasible direct replacement but also represents a performance upgrade in terms of bandwidth.
