Bias networks with radio frequency (RF) chokes can be implemented using different microstrip elements. They can have different advantages in terms of bandwidth and occupied area. However, sharp discontinuities of the transfer functions have been observed in these types of bias networks. In this paper they are explained by resonances generated within the DC path of the bias network. As the resonance behavior degrades the performance of broadband RF circuits, the robustness of different bias networks against resonance was investigated. Different bias networks were fabricated and measured. Both simulation and experimental results show that broadband microstrip bias networks can be optimized to avoid or reduce the resonance phenomena.
