1. AT-101V Substitution Conclusion
The substitution of the AT-101V for the original part is conditional, with the primary risk being insufficient frequency range. The operating frequency range of the AT-101V (0-18 GHz) is significantly lower than the original part's 32 GHz. Within the 18 GHz to 32 GHz band—commonly used in high-end microwave communications, radar, satellite, or test and measurement applications—the AT-101V will be unusable or may introduce unpredictable insertion loss and VSWR degradation, potentially leading to degraded system performance. Substitution is feasible if the actual application frequency is below 18 GHz and provided that key parameters such as power rating (2W), impedance (50Ω), and interface (SMA) are compatible.
2. SA26B-01 Substitution Conclusion
The substitution of the SA26B-01 for the original part is a highly viable, near-equivalent replacement, though verification is still recommended. The core discrepancy lies in the upper frequency limit. While the SA26B-01's frequency range (0-26 GHz) is superior to that of the AT-101V, it remains 6 GHz below the original part's 32 GHz capability. This gap could impact system bandwidth or measurement accuracy in extreme high-frequency applications, such as millimeter-wave front-end links. If the actual operating band is within 26 GHz, its electrical parameters (1dB attenuation, 2W power handling, 50Ω impedance) and mechanical form factor (SMA feed-through module) align with the original specifications, allowing it to be considered a direct substitute. However, it is advisable to validate its performance near the 26 GHz point at the system level to ensure it meets all requirements.
