Low cost Diplexer for High performance phased array antenna
ABSTRACT: Princeton Microwave Technology [PmT] is proposing the development of compact microstrip based dual mode resonators for the the design of the low cost diplexers for the GDPAA program.Miniature dual mode resonator based diplexers, in which the main feature and advantage lies in the fact that each of the dual mode resonators can be used as a doubly resonant circuit and therefore requires half the number of resonators for an nth degree filter, resulting in a compact configuration. High selectivity is offered by this approach resulting in isolation that will exceed specification at low insertion loss. Other resonator structures, such as balanced to unbalanced , and aperture coupled resonators will also be investigated to justify the choice. The filter structures will be studied for integration with LTCC or LTCC-M technologies . It is expected that the diplexer structures will cost around one dollar in large quantity and the technology will be US based. BENEFIT: The design of the compact diplexer will be very useful for S Band commercial application. These include telephone and tower structure and band selection switches. The technology and filter synthesis can be used up to higher frequencies.
