Design and analysis on power synthesis of all-solid-state pulse source with fast-edge

All-solid-state pulse source with fast-edge requires the feature of miniature, high stability, high repeatability and low power. In order to overcome low power of each pulser, the power synthesis with multi-pitch serpentine microstrip structure is established using ADS simulation software, the effect of power synthesis is confirmed. Using two high stability pulsers as the input of power synthesis module, the module can combine the two low power fast edge dual-exponential signals into one higher power signal. The test results show that the pulser can produce electromagnetic pulse with less than 2 ns falling time of negative pulse, about 10 ns pulse width and 1.1 kV peak voltage; after the two-signal synthesis, the module can produce pulse with 1.6 kV peak voltage, 2 ns falling time and 18 ns pulse width. The method can be extended to multi-pulser synthesis to obtain higher power.
