Zusammenfassung	We report on the development of a new single-stage high-frequency inductive voltage divider (HF-IVD) for Quantum Hall Resistance measurements at frequencies up to 2 MHz. The design, construction and testing of the HF-IVD are detailed, including effects of switching on any spike voltages and settling times after switching are found to be only a few micro-seconds. Measurements over the 200 kHz to 2 MHz range show that both the in-phase and quadrature relative voltage deviations are less than 2% at 2 MHz. These measurements will also be compared to an electrical HF equivalent circuit model of the HF-IVD and presented at the CPEM 2024.
