Design of Balanced Output High-Voltage Nanosecond Pulse Source for Symmetrical Antenna

Time-domain impulse generator is a very important unit in time-domain ultra-band radar systems. Most time-domain impulse antennas are symmetrically designed which require balanced output pulse generators in order to realize wideband matching. Aiming to solve the compatible problem of high voltage and balanced output, which commonly exists in high-voltage pulse generators, this paper designs a new pulse generator circuit, the cascade Marx circuit with balanced output. With this generator and a loaded bow-tie antenna, a 300 V nanosecond pulse was generated. The measured result validates the effectiveness of the proposed pulse generator.
