Abstract

The commercialization of millimeter wave frequencies for the 5G New Radio standard requires time and cost -effective testing equipment. The over-the-air measurement setup developed at the TU Delft (ADome) is able to reduce measurement time, by positioning multiple fixed sensing nodes around the antenna-under-test. To expand the system capabilities of the ADome, this work researches the possibilities of measuring signal quality by down-converting the high-frequency modulated signal to an intermediate frequency. This includes analysis on distributing the local oscillator to the sensing nodes, a proposed design and simulation of a passive single-balanced diode mixer circuit and simulated system EVM performance.
