Bipolar Reference Pulse Generation Device for Correlation Processing

This article discusses solutions to the problem of generating multipolar nanosecond pulses of increased amplitude with accurate time reference using simple technical implementations. A generator has been developed that generates bipolar pulses with an amplitude of 90-100V, a duration of 50 ns, and a pulse front of 5 ns. A fully matched and isolated combiner has been developed for the 0-100 MHz band, with an insertion loss of 4.4 dB and an isolation between inputs of at least 20.5 dB. A feature of this adder is the high isolation at low frequencies without the use of ferrite cores in the design.
