A Pulse forming network (PFN) converts direct current or alternating current to continous directional square pulses at high energy levels of high frequency. A pulse forming network circuit for storing energy in a thyratron modulator uses essentially a short section of an artificial transmission line. The output pulse is then applied to an oscillating device, such as a magnetron. Use of transformers in specific numbers can achieve an efficient match between a klystron and the pulse-forming network.
Used for:
Type "E" is the most generally used. Type "E" networks have equal capacitance per mesh. Type "E" networks have mutual inductance between adjacent coils.
