|RF-IV sensor base kit for the N2PK VNA. Use instead of T1-6T reflection bridge to expand impedance measurement range, increase measurements accuracy and calibration stability. Includes a PCB, two binocular cores for the RF transformers, and two lengths of #36 and #30 wire to wind the transformers - $20 including shipping worldwide by Airmail. Requires a few extra parts - download Digikey Bill of Materials. To learn more about the RF-IV method, download Paul N2PK's design documentation, and Agilent papers.|
|S-Parameters Test Set PCB for the N2PK VNA. Uses solid state RF switch ICs to change direction of the VNA RF output, allowing for measuring forward and reverse S-Parameters without reversing the DUT. This is a bare PCB - $15 including shipping worldwide by Airmail. Download build documentation.|
