In our experimental study, we investigated the performance of an electronically tunable phase shifter, operated by applying variable voltages, as depicted in Figure ) (device, constructed according to the description outlined in the Methods section (ref. 4.1)). A notable finding was the dependency of the phase shift on the applied voltage within the 25-40 GHz frequency range. We observed a linear relationship between the phase shift and increasing voltage, indicating significant tunability. Specifically, at 40 V, the device achieved a maximum differential phase shift of 28 In addition, we evaluate the insertion and return losses across the voltage spectrum. The insertion loss consistently remained below -4 dB, indicating efficient signal transmission. Up to 40 V, the return loss remained better than -23 dB, with a slight performance degradation observed at higher voltages. By analyzing the frequency response of the phase shifter in the 30 to 40 GHz range, we observed consistent performance, with minor deviations in the phase shift and loss parameters, underscoring its versatility across a broad frequency spectrum.
