Abstract
Military radio frequency (RF) and microwave amplifier system requires high level of reliability so it is implemented in modular structure. In this paper, Ultra high frequency (UHF) amplifier system with two levels and 4 parallel modules is simulated. The proposed system is investigated for better combining network (Gysel and/or Branch coupler). Also it is critically investigated for performance degradation due to failure in one module or more. Analysis of system failure is simulated by turning off one module or more. The results are represented in terms of Scattering parameters and degradation of the system output power versus number of failed modules. Microwave office software have been used for the design and failure analysis of the proposed system.
