High performance compact microwave filters for space applications

A dual mode dielectric resonator filter is designed, simulated and fabricated for a satellite telecommand receiver where high performance (low loss, high Q and narrow bandwidth filters) is required. Besides this, compact size and light weight is also a requirement. By using dual mode resonators the number of physical cavities is reduced by half and hence the size and mass is reduced. Full wave EM simulations and measurements of the designed filter are performed. Simulated and measured results of the proposed filter show good correlation.
