“…Essentially, this circuit is identical to the one for the simple case of a straight-cavity MPC (SMPC) as it is presented in [9], [14]. In brief, [14] uses an iterative procedure to calculate the optimal values for the waveguide cavity length, the opening of the inductive iris and the length of the short circuit at the output port of the compressor. The same procedure can be followed here, provided that the load impedance of Eq.…”

“…Such a gain optimization becomes a critical issue, since the increase of the MPC electrical length inherently suppresses the cavity gain [8], [9]. A simple yet effective approach to optimize the dimensions of a waveguide based MPC and maximize the cavity gain has been presented in [9], [14] and [15].…”

A microwave pulse compressor consisting of an iris, a straight waveguide section and a T-junction can be used in order to convert a long pulse with lower power to a shorter pulse with higher power. Provided that the system is designed precisely, a significant compression gain can be achieved. The duration of the compressed pulse is proportional to the cavity length, thus imposing a constraint to the development of mobile systems. In this work we present the circuit/transmission-line based design methodology that we follow in order to fold the cavity (while retaining the same electrical length) by using Tjunction turns. As an example, we design a 1.3 GHz folded compressor and we compare its performance to the corresponding one of a straight-cavity compressor. 3D full-wave simulations with CST Studio Suite and experimental measurements with the developed compressor confirm the accuracy of the proposed design methodology.
