Abstract
Systems are disclosed for providing a DC-bias network for a RF distributed amplifier. One embodiment may include a DC-bias network comprising a planar substrate having an input port configured to receive a DC input signal and provide a DC bias at an output port, a microstrip line mounted to the planar substrate and interconnecting the input port and the output port, and a plurality of RF resonators coupled to the microstrip line. Each of the plurality of RF resonators are configured to provide a substantially constant impedance for a respective portion of the frequency band of the RF signal.
