Abstract
An airline transmission structure in a low temperature co-fired ceramic ('LTCC'). A cavity is made within the LTCC structure. Ground planes surround the cavity. Electronic processing circuitry, such as an airline filter, is suspended within the cavity. Transmission lines are provided to connect the electronic circuitry to the electronic signals (typically microwave) which require processing. Full integration of the airline filter with other electronic circuitry in a single LTCC package is also shown.
