Impulse Generator Using UWB Pulse Forming Network

Development of a new nanosecond monocycle pulse generator with pulse forming network is presented along with detailed design and analysis. The developed pulse forming network is simple, compact, and can be realized using planar circuit. Formation of the impulse is a classical technique using the delay-line principle and implemented on microstrip structures. The pulse-shaping network employs a microstrip short-circuited stub. An impulse generation circuit using an SRD was made and the monocycle pulse was produced using the microstrip pulse forming network. The measured pulses have good symmetry and low ringing level.
