On-wafer noise figure measurements of millimeter-wave LNA and mixer

An on-wafer measurement technique is performed to characterize the noise figure (NF) at millimeter-wave (MMW) band. Two NF-measurement techniques are reviewed, and the Y-factor method is discussed in detail. The measurement principles and considerations are proposed for the device under test (DUT) at MMW band. The test procedure and setups are performed to measure the V-band amplifier and mixer. The experimental results confirm the validity with high accuracy by comparing with the simulations.
