Objectives
The objective is to demonstrate the low loss, mass and volume reduction for a high power filter at Ku Band using advanced dielectric material, considering all the high power issues associated with self-heating, multipaction, corona breakdown and PIM.
Development of a dielectrically loaded filter for use as a Ku Band High power channel filter will require a combination of proper materials selection and innovative cavity design. Recent advance in dielectric material with excellent microwave characteristics offers the potential of developing Ku dielectric OMUX. Paramount to success is the ability to limit heating and dissipate heat within the resonator assembly.
Challenges
Key issues are:
- Availability of high performance dielectric materials for implementation,
- Mechanical and thermal design of the dielectric loaded resonator filter,
- RF/mechanical/thermal performance optimisation.
Plan
The proposed study work is separated into two phases with five work packages. The first phase covers dielectric high power Ku-band filter design, material and suppliers research and development. The second phase covers Breadboard manufacturing, test and design validation.
Current Status
The project continues on plan and nears completion of formal testing. Significant test events such as mechanical and high power testing are complete. Hardware continues to meet or exceed expectation as the final stages of testing wrap up. Upcoming project events include completion of formal testing and preparation of final project reports. The project is on target for completion as planned.
