In the course of the Joint Research Activity BRAND (BRoad-bAND) of RadioNet4 we intend to develop the prototype of a true wide-band VLBI receiver for prime focus operation in the European VLBI Network (EVN). It will cover the frequency range of about 1.5 GHz to 15.5 GHz. The receiver will have a single wide-band feed and amplifier. The analogue signal will not be mixed, but sampled directly for further processing. We will describe the project together with some of the science drivers.
