Abstract :
A new time-varying matching network is proposed for pulse-based systems with RC loads. In the proposed design, the capacitors in the matching network and the load are pre-charged and connected to the system via switches when a pulse signal arrives. Compared with the conventional matching network that is limited by the gain-bandwidth restriction, the switched capacitor design of the proposed matching network greatly improves the matching performance in that 7-8 dB increase/decrease in the transmitted/reflected energy as well as little pulse-widening are observed in the experiments.
