1. SA26B-09 Substitution Conclusion The SA26B-09 can serve as a full drop-in replacement for the original part number FMAT7467-9. The key difference lies in the frequency range: the SA26B-09 supports 0 Hz to 26 GHz, whereas the original part is specified for 0 Hz to 12 GHz. Within the original application band of up to 12 GHz, the SA26B-09 exhibits identical electrical performance—including 9 dB attenuation, 50 Ω impedance, and 2 W power handling—and mechanical compatibility (SMA In-Line Module package). This ensures a direct replacement without modification. Moreover, the wider frequency range offers increased bandwidth margin, which enhances design flexibility and extends potential application to future systems that may require operation at higher frequencies, without introducing performance degradation or compatibility issues.

2. SA18E-09 Substitution Conclusion Similarly, the SA18E-09 is fully interchangeable with the original FMAT7467-9. The primary variation is in frequency coverage: the SA18E-09 supports 0 Hz to 18 GHz, compared to the original’s 0 Hz to 12 GHz. Across the original operating band up to 12 GHz, the attenuation, power rating, impedance, and package of the SA18E-09 match those of the original part, guaranteeing plug-and-play compatibility. The extended frequency range up to 18 GHz provides headroom for system upgrades or potential high-frequency applications, while maintaining existing performance levels. This allows for improved future applicability without compromising current compatibility.
