Effects of DUT mismatch on the noise figure characterization: A comparative analysis of two Y-factor techniques

摘要

Device mismatch seriously degrades accuracy inudnoise figure characterization. The suitability of corrections to the gain definitions for a more precise noise figure evaluation for mismatched devices is investigated and compared to classical techniques. The effects of device mismatch on the noise figure ofudthe noise-meter receiver and its impact on the final accuracy are analyzed.
