The mm-wave Broadwall couplers are essential components for RF systems. Couplers are normally divided into two categories based on their coupling level: the strong and weak coupling structures. Broadwall coupler falls in the category of weak coupling structures used for test and measurement purposes. Broadwall couplers can either sample in the forward or reverse direction, enabling various applications.

The power combining networks are essential assemblies in radar applications. The coverage range of the radar is limited by the available power. In this project, we aimed to construct a huge assembly to combine 32- power amplifier modules. The number of modules is large to reach 5000 watts of CW power in X-band.
