A number of LTCC circuits, modules and antennas have been developed in the past years during several R&D projects. Nearly all activities are related to mobile communication or sensoring application in RF or microwave frequency range. The table below summarises pictures of LTCC modules ordered by increasing frequencies. This gallery makes evident, that LTCC is capable to be used not only in DC and digital applications but also in the mobile communication frequencies like GSM and UMST. Furthermore LTCC has its advantages in wireless data transfer standards like Bluetooth or WLAN. The use for aerospace and space application as well as Radar sensoring has also been demonstrated for GHz- or ISM-band frequencies. For details about selected developments choose one of the following links. Please note, that IMST is a development house. These modules are not products from the shelf. They demonstrate the functionality for the specific application. IMST offers its customers to adapt these developments to their specific requirements or to find an applicable solution.
