A Novel Method for Synthesizing Blumlein Pulse-Forming Networks to Generate High-Gain Quasi-Rectangular Pulse

In this article, we propose a novel method for synthesizing Blumlein pulse-forming networks (PFNs) to generate high-gain quasi-rectangular pulses. First, a thorough analysis of the output response of Blumlein PFNs circuit is carried out. Next, the ideal output rectangular pulse function is examined and expanded in infinite products. Finally, by employing a finite number of terms in these products as an approximation of the output function and comparing it to the actual output function, the undetermined parameters are determined in the network’s characteristic impedance. Following that, the parameters of each component in the PFNs are derived using the conventional synthesis approach with the Cauer method. The detailed simulations have shown that our design approach is effective, and the designed Blumlein PFNs can achieve the expected results. This makes it a promising technique for applications that require high-gain rectangular pulses. The novel synthesis method presented in this article opens up new avenues for further exploration into additional design techniques, as well as broader application scope of this strategy in various fields.
