Abstract :
In the paper, the base device for a frequency division circuit (FDC) system is calculated. Evaluation of the characteristics with maximum approximation to theoretically ideal is carried out. A diplexer for the ground penetration radar is investigated using L and C lumped elements. The diplexer shows very small insertion loss, and the VSWR of less than 2.0 through the all pass-band. The theoretical analysis of the FDC is carried out basing of the differential equation method. The standard strategy of filter synthesis is applied for synthesis of the FDC structure.
