Abstract: An analytical approach is presented to achieve the design and development of High power RF Waveguide pressure window. The theroitical calculations are carried out in MATLAB and the simulations are carried out in High frequency structure simulator. This paper presents the detailed developmental work for realization of RF waveguide pressure windows used for Satellite testing applications. In this paper, the design is carried out in the Ka-band frequency with inductive type of iris.Alumina is chosen as dielectric for its high power handling capacity. Silicone gasket is used for attachment ofsubstrate to flange and for providing required level of vacuum sealing. Detailed process of Test and Qualification of Pressure window has been presented in this paper. Waveguide pressure windows have been developed at payload downlinkfrequencies in Ka-band and are being used for characterisation of Communication payload.
