A phased array antenna includes several antenna elements and a signal feed entry from or to which a signal is transmitted to or from the antenna elements. A phase shifting device modifies a phase difference of the signal that is transmitted from the signal feed network to the respective antenna element or that is transmitted from the respective antenna element to the signal feed network to adjust the preferred direction of radiation of the phased array antenna. A bias voltage is applied to each phase shifting device via two bias voltage electrode lines that are connected to a bias voltage driver. The bias voltage driver has several output channel terminal pairs with two output channel terminals to apply a tunable output channel voltage difference to each terminal pair. The two bias voltage electrode lines of each phase shifting device are connected to a respective terminal pair.
