A ganged circulator device for isolating a transmitter and increasing the power level, isolation performance, and input VSWR performance of an IBOC combiner module is provided. The ganged circulator device includes an input power divider, a ganged circulator module, and an output power combiner. The input power divider includes a first input port, a second input port, and a plurality of output ports. The ganged circulator module includes a plurality of circulators and a plurality of load resistors. The module also includes input ports corresponding to and electrically connected to the plurality of output ports on the input power divider. The output power combiner includes a first output port, a second output port, and plurality of input ports corresponding to and electrically connected to a plurality of output ports of the ganged circulator module. An input signal is applied at the first input port of the input power divider, and an output signal is transmitted from the second output port of the power combiner. A first load resistor is electrically connected to the second input port of the power divider, and a second load resistor is connected to the first output port of the power combiner.
